+ GNU LIBRARY GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+ 675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL. It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it. You can use it for
+your libraries, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library. If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+\f
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software. To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+ Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs. This
+license, the GNU Library General Public License, applies to certain
+designated libraries. This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+ The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it. Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program. However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+ Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries. We
+concluded that weaker conditions might promote sharing better.
+
+ However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves. This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them. (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.) The hope is that this
+will lead to faster development of free libraries.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+ Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+\f
+ GNU LIBRARY GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License"). Each licensee is
+addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+\f
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+\f
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+\f
+ 6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ c) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ d) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+\f
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+\f
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+\f
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ Appendix: How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Library General Public
+ License as published by the Free Software Foundation; either
+ version 2 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Library General Public License for more details.
+
+ You should have received a copy of the GNU Library General Public
+ License along with this library; if not, write to the Free
+ Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the

+ would cause motion notify events not to be delivered.
+
+Sun Oct 5 18:15:06 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gtk/gtkrc.c (gtk_rc_parse_bg_pixmap): Changed strdup() for
+ g_strdup().
+
+Wed Sep 24 17:16:34 1997 Peter Mattis <pmattis@bjork.inktomi.com>
+
+ * configure.in: Fixed a stupid error in the test for libXext that
+ would cause it to fail if X_EXTRA_LIBS was not empty.
+
+ * gtk/gtkmain.h (gtk-timj-970919.patch):
+ * gtk/gtkmain.c (gtk-timj-970919.patch): new function
+ `gtk_idle_remove_by_data' to remove all idle callbacks that take a
+ specific piece of data as argument. (gtk_get_current_event):
+ remove idles through gtk_idle_remove_by_data.
+
+ * gtk/gtkwidget.c (gtk-timj-970919.patch):
+ (gtk_widget_destroy): remove pending idles for
+ widgets that have GTK_REDRAW_PENDING or GTK_RESIZE_PENDING and
+ GTK_ANCHORED set (only anchored widgets can have a resize queue
+ handler pending). widgets that have GTK_RESIZE_NEEDED will be removed
+ from their anchored toplevels `resize_widgets' list.
+
+ (gtk_widget_queue_draw): let the widget remember the queue handler
+ tag (through `redraw_handler_key') for later call to `gtk_idle_remove'.
+
+ (gtk_widget_queue_resize): let the widget remember the queue handler
+ tag (through `resize_handler_key') for later call to `gtk_idle_remove'.
+ corrected referencing the toplevel widget for which the handler is
+ pending. if a widget is added to the `resize_widgets' list of a
+ toplevel widget, GTK_RESIZE_NEEDED is set and it's referenced.
+
+ (gtk_real_widget_queue_resize): on the deletion of the `resize_widgets'
+ list, unset GTK_RESIZE_NEEDED and unreference the removed widgets.
+
+ * gtk/gtkwindow.c (gtk-timj-970919.patch):
+ (gtk_real_window_move_resize): move `resize_containers = NULL'
+ initialization out of if-statement.
+ while stepping through the `resize_widgets' list, unreference the
+ widgets and clear GTK_RESIZE_NEEDED. if a widget realy needs are
+ resize, they are flagged through GTK_RESIZE_NEEDED now (instead of
+ GTK_RESIZE_PENDING, as this is indicative for a pending handler).
+ added checks to provide segfaulting if a widgets parent pointer
+ is NULL (e.g. on toplevel widgets that have GTK_RESIZE_NEEDED set).
+
+Tue Sep 23 13:23:27 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gdk/gdkimage.c: Applied Tim Janik's patch to mark shm segments
+ as IPC_RMID so that they are automatically removed always.
+
+ * gdk/gdkfont.c: Removed casts from lvalues.
+
+ * gtk/gtkmain.c: Removed GTK_RETLOC_*() (which do a cast) from lvalues.
+
+ * gtk/gtkaccelerator.c (gtk_accelerator_table_remove): Added
+ "const" to the accelerator_key param to be consistent with the
+ declaration in gtkaccelerator.h. The const is not useful in this
+ case, anyway.
+
+Tue Sep 16 13:11:06 1997 Peter Mattis <pmattis@bjork.inktomi.com>
+
+ * gtkpreview.c: Andrew Logan Kieschnick's change to eliminate
+ round-off error when gamma is set to 1.0.
+
+ * gtkrange.c:
+ * gtkviewport.c: Jay Painter's changes to modify the way in which
+ viewports resize.
+
+ * gdkinput.c:
+ * gdkinputgxi.h:
+ * gdkinputxfree.h:
+ * gtk/Makefile.am:
+ * gtk.h:
+ * gtkeventbox.c:
+ * gtkeventbox.h: Owen Taylor's event box widget and fixes for X
+ input support (that I had broken).
+
+ * gdk.h:
+ * gdkwindow.c:
+ * gtksignal.h:
+ * gtksignal.c: Elliot Lee's changes to support Objective C. (id is
+ apparently a reserved word in Objective C).
+
+Sun Sep 14 22:33:15 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c (gtk_widget_queue_resize): If the toplevel container
+ is invisible we simply call "gtk_container_need_resize" on
+ it. This fixes a bug with option menus not redrawing correctly.
+
+ * gtkmenuitem.c (gtk_menu_item_enter): (gtk_menu_item_leave):
+ These functions now simply pass the event on to their parent. This
+ is necessary for menus to work properly due to the change in how
+ grabs are dealts with.
+
+ * gtkwindow.c (gtk_real_window_move_resize): Fixed a bug that
+ caused the GTK_RESIZE_PENDING flag to not be unset in some cases.
+
+Fri Sep 5 20:49:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
+
+ Bug fixes:
+
+ * Makefile.am: Added PATCHES to EXTRA_DIST.
+ * gtk/gtkpixmap.c (gtk_pixmap_new): Move the "pixmap != NULL" test
+ after the allocation of the pixmap.
+
+ To shut up the compiler:
+
+ * gtk/gtkfilesel.c (get_pwdb): Initialize home_dir.
+ * gtk/gtkmain.c (gtk_init): Replace comments around calls to
+ g_set_*_handler with "if (0)".
+ * gtk/gtkrc.c (gtk_rc_get_token): Initialize hex_number and
+ float_number.
+ * gtk/gtkwindow.c (gtk_window_key_press_event): Initialize
+ direction.
+
+ Changes to the type system in gtk/:
+
+ * Makefile.am: Added gtktypebuiltins.h to gtkinclude_HEADERS.
+ Added gtk.defs, runelisp, gentypeinfo.el and gtktypebuiltins.c to
+ EXTRA_DIST. Added rules to generate gtktypebuiltins.* from
+ gtk.defs.
+
+ * runelisp, gentypeinfo.el, gtk.defs: New files.
+
+ * gtkaccelerator.c, gtkaccelerator.h (gtk_accelerator_table_ref):
+ Return the table so that this function can be used as the `copy'
+ function for GTK_TYPE_BOXED values.
+ * gtkstyle.c, gtkstyle.h (gtk_style_ref): Likewise.
+
+ * gtkenums.h: Removed GtkArgType enum.
+
+ * gtkmain.c (gtk_init): Call gtk_type_init to initialize the type
+ system.
+
+ * gtkobject.c (gtk_object_init_type): New function to take over
+ for gtk_object_get_type. (gtk_object_get_type): Just return the
+ constant GTK_TYPE_OBJECT. (gtk_object_collect_args): Do the right
+ thing for the new GTK_TYPE_* types.
+ * gtksignal.c (gtk_params_get): Likewise.
+
+ * gtktypeutils.c: (gtk_type_init_builtin_types): New
+ function. (gtk_type_init): Call it. Also made non-static.
+ (gtk_type_unique): The allocation scheme for numerical ids has
+ changed: The low 8 bits hold the appropriate GtkFundamentalType of
+ a type, the rest is a globally unique sequence number.
+ (gtk_type_hash): Use the sequence number of a key to hash it.
+ (gtk_type_register_builtin): New function.
+
+ * gtktypeutils.h: (GtkFundamentalType): New enumeration of the
+ fundamental types. (GTK_TYPE_MAKE, GTK_FUNDAMENTAL_TYPE,
+ GTK_TYPE_SEQNO): New macros to work with the new id scheme.
+ (GtkArg): Added fields for new types and renamed old ones. GtkArg
+ should now be a mostly opaque structure, except name and type.
+ (GTK_VALUE_*): New macros to access the values of a GtkArg.
+ (GTK_RETLOC_*): New macros to access the location of a return
+ value that is contained in a GtkArg. * gtktypebuiltins.h: New
+ file to access the typeids of the builtin types.
+
+ * gtkwidget.h (GTK_TYPE_WIDGET): New macro to access the type id
+ of the widget class.
+
+ Thru out: Changed GTK_ARG_* to the appropriate GTK_TYPE_*.
+ Changed access to GtkArg structure to the appropriate GTK_VALUE_*
+ or GTK_RETLOC_* macro. Changed GtkArgType to GtkType. Changed
+ some guints to GtkType.
+
+ General changes in gtk/ to support interpreters:
+
+ * gtkradiobutton.c (gtk_radio_button_new_from_widget,
+ gtk_radio_button_new_with_label_from_widget): New functions.
+
+ * gtksignal.c (gtk_signal_connect_no_marshal): New function.
+ (struct _GtkHandler): Added no_marshal and destroy_func fields.
+ (gtk_signal_handler_new): Initialize them.
+ (gtk_signal_connect_by_type): Added no_marshal and destroy_func
+ arguments. Changed all callers.
+ (gtk_signal_destroy): Invoke destroy_func if there is one and the
+ global destroy func does not apply. (gtk_handlers_run): If the
+ handler has no_marshal set, call its function directly without
+ going thru the signal's marshaller.
+
+Wed Sep 3 09:56:22 1997 RHS Linux User <pmattis@bjork.inktomi.com>
+
+ * gtkrange.c: Changed the way the range control focus was drawn so
+ that the range control is drawn correctly when it does not have
+ the focus.
+
+Tue Sep 2 17:41:17 1997 RHS Linux User <pmattis@bjork.inktomi.com>
+
+ * gtkwidget.c: 'gtk_real_widget_queue_resize' should only remove
+ the "resize_widgets" if another resize is not pending.
+
+Mon Sep 1 18:28:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmain.c: Changed the way GDK_DELETE events are handled. Only,
+ if 'gtk_widget_event' returns TRUE is the widget destroyed. By
+ default, 'gtk_widget_event' will return FALSE causing the window
+ to not be destroyed. This prevents segfaults in the GIMP and other
+ programs that do not correctly handle GDK_DELETE events.
+
+ * gtkmain.c: Added modal dialog support by allowing events
+ destined for a child of the grab widget to go to the child instead
+ of the grab widget. (Added 'gtk_widget_is_ancestor' to determine
+ the relationship between the grab widget and the event widget).
+
+ * *.[ch]: Incorprated a whole mess of patches. (Started keeping
+ the ChangeLog up to date again).
+
+Thu Jun 5 17:22:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c:
+ * gtkmenufactory.h: Added 'gtk_menu_factory_remove_*'
+ calls. Removing entries/paths causes the associated widgets to be
+ destroyed.
+
+ * gtkwidget.c:
+ * gtkwidget.h: Calling 'gtk_widget_set_style' is used as an
+ indication that the programmer specifically wants that style to be
+ used. RC-style substitution is disabled for the widget after such
+ a call.
+
+ * gtkpixmap.c:
+ * gtkpixmap.h:
+ * gtkimage.c:
+ * gtkimage.h: Changed to use clip mask and a single pixmap (or
+ image) to deal with transparent areas.
+
+ * gdkpixmap.c: Modified xpm loading routines to optionally return
+ a clip mask.
+
+ * gdkgc.c:
+ * gdkdraw.c:
+ * gdktypes.h: Modifications to allow clip masks to be used with
+ gc's. Clip masks are bitmaps that specify drawable regions.
+
+Thu May 1 03:11:51 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkscrolledwindow.c: Scrolled windows need to have the
+ GTK_NO_WINDOW flag set. Not having it set caused an obscure
+ redrawing bug.
+
+Wed Apr 30 12:38:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkhruler.c:
+ * gtkvruler.c: Fixed a small bug that caused the indicator to be
+ positioned slightly off.
+
+Sun Apr 27 14:28:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c:
+ * gtkmenushell.h:
+ * gtkmenu.c:
+ * gtkmenu.h: Changes so that if a menu is popped up there is a
+ timeout period during which a menu item will not be activated and
+ if the mouse button is released in that period the menu will stay
+ popped up.
+
+ * gtkcurve.c:
+ * gtkcurve.h: Included curve widget courtesy of David
+ Mosberger-Tang (davidm@azstarnet.com).
+
+ * gtkentry.c:
+ * gtkentry.h: Changed "insert" and "delete" signals to
+ "insert_text" and "delete_text" respectively. (The symbol "delete"
+ cannot be used since it is a C++ reserved word).
+
+Sat Apr 19 01:43:49 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c: A path which ends in "<nothing>" will cause an
+ invisible (hidden) menu entry to be created. This is useful for
+ setting an accelerator key for which a corresponding menu entry is
+ not desired.
+
+ * gtktooltips.c: Fixed some problems with destruction of the
+ active tip widget not properly updating the tooltips data
+ structures.
+
+Fri Apr 18 15:09:45 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcontainer.c:
+ * gtklist.c:
+ * gtkwidget.c:
+ * gtkwidget.h: Patch from Owen Taylor (owt1@cornell.edu) which
+ fixes problems with destruction of objects and with destruction of
+ objects which hold the focus.
+
+Thu Apr 17 11:29:15 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c: Incorrect logic in
+ 'gtk_menu_shell_button_release' for deciding when a menu should
+ stay popped up when the mouse button is released.
+
+ * *.c: Miscellaneous fixes from folks on the net.
+
+Tue Apr 15 02:43:17 1997 Peter Mattis <pmattis@localhost>
+
+ * *.c:
+ * gtkwidget.h: Added GTK_BASIC widget flag which when set
+ specifies a widget as "basic". A "basic" widget is one which
+ doesn't take input events. For example, labels, pixmaps, boxes,
+ tables, alignments, etc.
+
+Sat Apr 12 15:23:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcolorsel.c: Add "#include <math.h>" to define M_PI.
+
+ * gtksignal.c: Fixed a bug in 'gtk_signal_emit' which showed up
+ because of the new cast checking macros. The 'object' was being
+ accessed after it had been destroyed.
+
+ * gtkoptionmenu.c: Fixed bug with using 'GTK_BIN' instead of
+ 'GTK_BUTTON' which showed up because of the new cast checking
+ macros.
+
+ * *.h: 'GTK_CHECK_CAST', 'GTK_CHECK_CLASS_CAST' and
+ 'GTK_CHECK_TYPE' used by standard widget macros everywhere.
+
+Wed Apr 9 00:54:17 1997 Peter Mattis <pmattis@localhost>
+
+ * docs/gtk.texi: Started further work on documentation. Major
+ changes and additions are being made.
+
+ * gtkarrow.c:
+ * gtkarrow.h: Removed function 'gtk_arrow_get'.
+
+ * gtkcontainer.c: 'gtk_container_check_resize' no performs
+ additional checking to account for the case where the containers
+ allocation is no longer sufficient because its parent (or its
+ parents parent, etc.) needs to resize its children.
+
+Tue Apr 8 21:15:50 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkstyle.c: Fixed a bug in 'gtk_style_init' in which the font
+ was not ref'd (via 'gdk_font_ref'), but was free'd (via in
+ 'gdk_font_free') in 'gtk_style_destroy'. (David
+ Mosberger-Tang). Also cleaned up 'gtk_style_destroy' while I was
+ at it.
+
+ * gtkmain.c: Fixed a bug in 'gtk_propogate_event' which caused
+ entry widgets (and probably other widgets) not to be destroyed in
+ some instances.
+
+Mon Apr 7 01:20:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkentry.c:
+ * gtkentry.h: Changed the "insert_text", "delete_text" and
+ "changed_text" signals to "insert", "delete", and "changed"
+ respectively. They really should have been named this way
+ originally except the previous signal mechanism prevented
+ duplicate signal names. ("changed" is also used by adjustments).
+
+ * gtkradiomenuitem.c:
+ * gtkradiomenuitem.h: New widget.
+
+ * gtkcheckmenuitem.c:
+ * gtkcheckmenuitem.h: New widget.
+
+ * gtksignal.c: Modified 'gtk_signal_lookup' to require an object
+ type to be passed as a parameter. In addition, signals are now
+ only needed to be uniquely defined in their branch of the class
+ hierarchy. This allows the same signal name to be used in two
+ different branches of the class hierarchy. For instance, the
+ "changed" signal is used both by adjustments and entries...in
+ different ways!
+
+ * gtktypeutils.c: Added 'gtk_type_parent' which returns the parent
+ type for a given type.
+
+Sun Apr 6 22:08:35 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c: If a widget is set insensitive it loses the focus
+ if it had it.
+
+ * gtkcontainer.c: Insensitive widgets no longer participate in tab
+ traversal.
+
+ * gtkscrolledwindow.c: The "viewport" child is now destroyed and a
+ container class "foreach" function was written (which fixes the
+ sensitivity bug).
+
+Sat Apr 5 14:25:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkhscrollbar.c:
+ * gtkvscrollbar.c: Fixed trough size allocation bug.
+
+ * gtkhscale.c:
+ * gtkvscale.c: Fixed trough size allocation and position bug that
+ showed up when scales were placed in notebooks.
+
+Thu Mar 27 17:45:54 1997 David Mosberger-Tang <davidm@azstarnet.com>
+
+ * gtk/gtkmain.c (gtk_handle_idle): Fix appending pending_idles to
+ idle_functions so it works even when idle_functions is empty.
+
+Sat Mar 15 14:15:59 1997 Peter Mattis <pmattis@localhost>
+
+ * *.[ch]: Moved '*_class_init' and '*_init' function declarations
+ for widgets into the source file as those functions no longer had
+ to be public.
+
+ * gtkcheckbutton.c: Fixed redrawing of check button.
+
+ * gtkframe.c: Fixed redrawing of frame when the shadow type is
+ changed.
+
+Sat Mar 8 15:19:23 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkimage.c: Fixed a stupid bug with 'gdk_image_new' which
+ potentially added a NULL image to "image_list" and caused problems
+ when 'gdk_image_exit' was called.
+
+Wed Mar 5 00:40:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkpreview.c: Massively changed the colormap handling used by
+ the preview widget. Gray previews are now dithered. A single
+ visual and colormap is shared by the color and gray previews. A
+ GTK_PREVIEW_INFO property is installed on the root window in
+ certain cases to allow multiple GTK programs to share the system
+ colormap.
+
+Sun Mar 2 05:43:06 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcheckbutton.c: 'gtk_checkbutton_size_allocate' was allocating
+ too much space to its children and not leaving the check button
+ room for the focus border.
+
+ * gtknotebook.c: 'gtk_notebook_size_request' wasn't requesting
+ enough space when the notebook tabs are visible.
+
+Sat Mar 1 01:59:35 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkpreview.c: Fixed a problem with 'gtk_preview_put' when the
+ image byte order is GDK_MSB_FIRST.
+
+ * gtksignal.c:
+ * gtksignal.h: Added 'gtk_signal_connect_after' and
+ 'gtk_signal_connect_object_after' functions. These connect signal
+ handlers which will run after the class function associated with
+ the signal.
+
+ * gtkstyle.c: Fixed a stupid bug in 'gtk_style_new_from_key' that
+ was causing twice as many styles to be created as necesary.
+
+ * gtkwidget.c: 'gtk_real_widget_size_allocate' erases the widgets
+ old allocation if it has the GTK_NO_WINDOW flag set.
+
+ * gtkwidget.c: 'gtk_real_widget_unmap' now erases the widget if it
+ has the GTK_NO_WINDOW flag set.
+
+ * gtklabel.c: Removed 'gtk_label_unmap' as similar functionality
+ was added to gtk_real_widget_unmap.
+
+ * gtkbin.c: Modified 'gtk_bin_map' and 'gtk_bin_unmap' so that it
+ erases and draws the widget if it has the GTK_NO_WINDOW flag set.
+
+ * gtkframe.c: Modified 'gtk_frame_size_allocate' so that it erases
+ the old allocation.
+
+Fri Feb 28 03:27:05 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: 'gtk_window_set_title' now changes the window title
+ if the window is already realized.
+
+ * gtkentry.c: 'gtk_entry_set_text' was emitting both a
+ "delete_text" and a "changed_text" signal. Modified so that it
+ only emits a "changed_text" signal.
+
+ * gtkpreview.c: Modified to work correctly on systems with MSB
+ byte order. The colormap for TRUE and DIRECT color displays is now
+ created if the default visual is not equal to the visual we are
+ using.
+
+ * gtkstyle.c: 'gtk_style_attach' and 'gtk_style_find' weren't
+ working properly in the presence of multiple colormaps are
+ different depth visuals.
+
+ * gtkcontainer.c: Massively improved focus traversal using tab and
+ arrow keys. It now uses the layout of the widgets to determine
+ where to move the focus to.
+
+Mon Feb 24 03:24:02 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c: Set the accelerator table field for menus when
+ they are created.
+
+ * gtkmenu.c:
+ * gtkmenu.h: Added a default accelerator table field to menus so
+ that runtime modification of accelerator keys in menus can work
+ better.
+
+ * gtkrange.c: 'gtk_range_default_{h,v}motion' had faulty logic for
+ deciding what to do when the slider was at the edge of the
+ trough. They previously didn't update the adjustment value event
+ if the value wasn't what it should be when the slider was at the
+ edge of the trough.
+
+ * gtkviewport.c: 'gtk_viewport_size_allocate' and
+ 'gtk_viewport_adjustment_value_changed' both had the potential for
+ performing a divide by 0. Checks are now in place to prevent this.
+
+ * gtkmenu.c: 'gtk_menu_map' now makes sure the menu lies on screen
+ if the position function is NULL.
+
+ * gtkentry.c: Modified selection handling. 'gtk_delete_selection'
+ actually removes the X selection now. 'gtk_entry_destroy' removes
+ the selection as well and relies on the change in "gdk.c" to make
+ sure the selection event will not be sent to a non-existant
+ window.
+
+ * gdk.c: Selection events are only passed on if the selection
+ owner is not NULL.
+
+ * gtkstyle.c: 'gtk_style_detach' and 'gtk_style_destroy' were not
+ destroying the black and white gc's.
+
+Sun Feb 23 19:17:56 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: 'gtk_window_size_request' was setting the window
+ hints. This was also being done in 'gtk_window_map', so the
+ instance being done in 'gtk_window_size_request' was removed.
+
+Fri Feb 21 01:04:01 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c: 'gtk_widget_draw' has to use the widgets allocated
+ position for the drawing rectangle when the widget has the
+ GTK_NO_WINDOW flag set.
+
+ * gtkwidget.c: In 'gtk_widget_init' the visual and colormap were
+ being directly compared against 'default_visual' and
+ 'default_colormap' instead of calling
+ 'gtk_widget_get_default_{visual,colormap}'.
+
+ * gdkrectangle.c: Amazing! There was a bug in the
+ 'gtk_rectangle_intersect' logic. Its been there for near eternity
+ and I never noticed.
+
+ * gtkpreview.c:
+ * gtkpreview.h: Created preview widget which allows drawing to an
+ rgb or grayscale buffer which is automatically displayed on the
+ screen. Performs dithering as necessary.
+
+Thu Feb 20 20:33:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkwindow.c: Modified the logic in 'gdk_window_new' which
+ determined when to add a window to the WM_COLORMAP_WINDOWS
+ property.
+
+Wed Feb 19 19:55:29 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkruler.c: 'gtk_ruler_make_pixmap' was always destroying the
+ old backing store and creating a new one even when it would create
+ a new one of exactly the same size as the old one.
+
+Tue Feb 18 18:32:10 1997 Peter Mattis <pmattis@localhost>
+
+ * gmem.c: 'g_mem_chunk_alloc' was incorrectly modifying the mem
+ areas free mem field when reallocating a previously freed
+ atom. This caused a fairly severe memory leak.
+
+ * gtkmenushell.c: 'gtk_menu_shell_button_release' had a bug in the
+ logic for deciding whether to initiate an X pointer grab or not
+ when the mouse button was released. It now only initiates a grab
+ if the mouse is released within an active menu item.
+
+Fri Feb 14 00:57:40 1997 Peter Mattis <pmattis@localhost>
+
+ * gtknotebook.c: Changed the look of notebook tabs slightly.
+
+ * gtkentry.c:
+ * gtkentry.h: Deleting an entry widget which is holding the X
+ selection presents some difficulties. The X selection must be
+ released, but the widget can't be destroyed until the
+ SELECTION_CLEAR event is received that the X server will send in
+ response to clearing the X selection. There are probably still
+ bugs in the current method of entry widget deletion when the X
+ selection is held.
+
+ * gtkmain.c: 'gtk_propagate_event' was not properly destroying the
+ toplevel window when receiving a key press event.
+
+ * gtkwidget.c: Setting a widget insensitive did not cause it to
+ redraw. It now does.
+
+Thu Feb 13 16:59:07 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkviewport.c: 'gtk_viewport_size_allocate' was allocating its
+ child widget an adjusted allocation. Since the actual scrolling
+ has handled by a subwindow this caused the child to be double
+ scrolled. Modified to always set the child allocations origin to
+ (0, 0).
+
+Wed Feb 12 01:06:48 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkentry.c: Text is now centered vertically. Previously it was
+ pushed up against the top. This problem was only evident when the
+ widget was allocated more vertical space than it requested.
+
+ * gtkfilesel.c: 'gtk_file_selection_key_press' was previously only
+ a stub for tab completion. The actual tab completion call had been
+ left out. (Oops!)
+
+Tue Feb 11 01:43:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtksignal.c: 'gtk_signal_disconnect_by_data' was going into a
+ loop and crashing. Bad logic. Fixed.
+
+ * gtkmain.c: An idle function which returns FALSE will be removed
+ from the list of idle functions. This makes the functioning of
+ idle functions and timeouts more similar.
+
+ * gtkentry.c: 'gtk_entry_get_text' now returns an empty string
+ when the actual text is NULL. This allows "stupid" programs to use
+ the value returned by 'gtk_entry_get_text' blindly (without
+ checking to see if its NULL).
+
+ * gtkradiobutton.c: Modified 'gtk_radio_button_clicked' so that
+ 'gtk_toggle_button_toggled' is called _after_ the widget state is
+ changed.
+
+ * gtksignal.c:
+ * gtksignal.h: Added 'gtk_signal_name' which returns the character
+ string name for a given signal number.
+
+ * gtkwidget.c: 'gtk_widget_set_parent' checks to see if the widget
+ is now "anchored" through the parent chain to a widget which is
+ GTK_ANCHORED. If it is, then it changes the widgets style using
+ 'gtk_rc_get_style' and recursively performs the same operation on
+ the widgets children. This is necessary is 'gtk_rc_get_style' only
+ works properly on "anchored" widgets.
+
+ * gtkwindow.c: Modified GTK_WIN_POS logic so that it is only used
+ immediately after the window has been shown.
+
+ * gtkmenu.c: 'gtk_menu_key_press'. Can now change menu item
+ accelerator keys on the fly. Why? Why not. Cool/useless feature of
+ the day.
+
+ * gtkmenuitem.c: Accelerator key drawing. Somehow that never got
+ finished. (Oops!)
+
+ * gtkdrawingarea.c: 'gtk_drawing_area_size_allocate' was not
+ actually installed during 'gtk_drawing_area_class_init'. (Oops!)
+
+ * gtkframe.c: 'gtk_frame_size_request' fixed size requisition
+ problem caused by unsigned arithmetic.
+
+ * gtkwindow.c: Modified window widget so that it only uses the
+ widget uposition auxiliary information immediately after it has
+ been shown. This prevents the annoying bug which can cause a
+ uposition'ed window to jump back to its original position after
+ the user moves it.
+
+ * gtkwidget.c: Need to ref and unref style in
+ 'gtk_widget_{push,pop}_style' to make sure that a style on the
+ style stack is not destroyed.
+
+ * gtktogglebutton.c: 'gtk_toggle_button_set_state' now calls
+ gtk_button_clicked to actually change the state of the
+ button. In this way, radio buttons can now perform the appropriate
+ actions when the toggle button state is set.
+
+Mon Feb 10 00:27:39 1997 Peter Mattis <pmattis@localhost>
+
+ * gtklist.c: 'gtk_list_select_item' and 'gtk_list_unselect_item'
+ were casting a GList* variable to a a GtkWidget* variable. Bad bad
+ bad. (Tim Janik).
+
+ * gtksignal.c: Modified 'gtk_signal_connect' and
+ 'gtk_signal_connect_object' to warn when a signal type cannot be
+ found.
+
+Sun Feb 9 00:15:30 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkoptionmenu.c:
+ * gtkoptionmenu.h: Changed option menus back to being derived from
+ buttons. This fixes up some screwiness with their user
+ interaction.
+
+ * gtkwindow.c: Modified key press handler to support focus
+ traversal.
+
+ * gtkcontainer.c:
+ * gtkcontainer.h: Added default focus traversal back in.
+
+Sat Feb 8 10:44:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkviewport.h:
+ * gtkviewport.c: Massively sped up viewport scrolling. Used to be
+ reallocating child's size (offset) each time a scrollbar
+ moved. Now a subwindow is moved. All the children are moved
+ automatically by moving the subwindow. Much much much faster.
+
+Tue Feb 4 00:20:44 1997 Peter Mattis <pmattis@localhost>
+
+ * gtree.c: Changed 'g_tree_node_search' to use a loop instead of
+ recursion.
+
+Mon Feb 3 11:30:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkbutton.c: Removed 'parent_destroy' global and replaced it
+ with 'parent_class' global to reflect style used in other
+ widgets.
+
+ * gtknotebook.c: Tab labels were being allocated less than their
+ requested size.
+
+ * gtkrange.c:
+ * gtkrange.h: Moved the "digits" field of scales into the range
+ type. The adjustment value for scales is truncated to the number
+ of visible digits instead of being left untouched.
+
+ * gtree.c: Fixed a bug in the AVL tree implementation. Single
+ rotations were always being performed during insertion. It is
+ sometimes necessary to perform a double rotation.
+
+ * gtklabel.c: Modified 'gtk_label_expose' to only draw the label
+ when the allocated space is greater than or equal to the requested
+ space.
+
+ * gtklabel.c: Added call to 'gtk_widget_unmap' to
+ 'gtk_label_destroy' in order for the label to redraw correctly
+ (erase itself) when destroyed.
+
+ * gtklabel.c: Added 'gtk_label_unmap' call which erases the labels
+ allocation when it gets unmapped.
+
+ * *.h: Removed a few remaining instances of using "class" as a
+ parameter name. (Causes problems for C++).
+
+Fri Jan 31 12:26:50 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcontainer.c: 'gtk_container_enable_resize' needs to call
+ 'gtk_container_check_resize' instead of
+ 'gtk_container_need_resize'.
+
+ * gtkwidget.c: 'gtk_real_widget_show' now maps the widget if its
+ parent is mapped.
+
+ * gtkscrolledwindow.c: Fixed size allocation when the scrollbar
+ policy's are GTK_POLICY_AUTOMATIC. Doing it correctly is harder
+ than I originally thought.
+
+ * gtklist.c: Added 'gtk_list_child_position' to determine the
+ integer position in a list of a child. Filled in the
+ 'gtk_list_item_select' and 'gtk_list_item_unselect' stubs.
+
+Thu Jan 30 16:08:06 1997 Peter Mattis <pmattis@localhost>
+
+ * gmem.c: Changed the implementation of G_ALLOC_AND_FREE mem
+ chunks. They used to allocate SIZEOF_VOID_P extra bytes per atom
+ in order to keep track of which mem area they were allocated
+ from. Now the mem area is determined by searching through an AVL
+ tree of the mem areas for a mem chunk and comparing memory
+ locations. A little slower, but makes G_ALLOC_AND_FREE mem chunks
+ much more attractive.
+
+ * gtree.c: Added an AVL tree implementation to glib.
+
+ * gtksignal.c:
+ * gstring.c: va_arg (arg_list, {char, short}) is
+ invalid. Arguments passed in a variable argument list are
+ promoted. ({char, short}->int). Seemed to work ok before under
+ Linux. Crashed under FreeBSD.
+
+Tue Jan 28 02:27:51 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkwindow.c: Fixed a major slowdown apparent in the file
+ selection dialog which was caused by calling
+ 'gtk_window_add_colormap_windows' way way way too often.
+
+ * *.c: Many widgets called 'gtk_container_need_resize' when
+ something internal changed which would cause the widget to grow or
+ shrink. The assumption was made that the widget would change size
+ and an expose event would be generated. This happens "most" of the
+ time. But its possible for certain widgets to change size without
+ generating expose events, or for its internal geometry to change
+ without a change of size which would mean no expose event was
+ generated. So a wrapper function called
+ 'gtk_container_check_resize' was created and
+ 'gtk_container_need_resize' was modified so that it returns FALSE
+ if a resize was actually generated and TRUE if nothing
+ changed. This allows 'gtk_container_check_resize' to initiate a
+ 'gtk_widget_size_allocate' and 'gtk_widget_draw' to emulate the
+ expose event.
+
+Sat Jan 25 14:17:44 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmain.c: Fixed a bug with propogating key press events. The
+ events were sent 2 times to the toplevel windows which caused the
+ focus widget to be activated twice when the space bar was pressed.
+
+ * */configure.in:
+ * */Makefile.am: Added support for libtool and removed the old
+ shared library configuration craziness.
+
+Fri Jan 24 12:59:22 1997 Peter Mattis <pmattis@localhost>
+
+ * gtktext.c:
+ * gtktext.h: Josh's fixes and additions to the text widget.
+
+ * gtkfill.c:
+ * gtkfill.h: Filler widget useful for filling space in a
+ table. Can specify a minimum size. Used by the canvas widget.
+
+ * gtknotebook.c:
+ * gtknotebook.h: Made outline of notebook widget.
+
+ * gtkcanvas.c:
+ * gtkcanvas.h: Started canvas widget. A composite of 2 rulers (w/
+ an origin), 2 scrolllbars. Guides, grids, snap to.
+
+Sun Jan 19 18:26:45 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkdialog.c:
+ * gtkdialog.h: Created dialog widget which creates a standard
+ looking dialog with buttons along the button and a separator.
+
+ * gtkxid.c: Generalized the window table code for looking up a gdk
+ window based on an XID to work for any XID and a piece of
+ data. Can now look up gdk fonts based on their XID.
+
+ * gtkruler.c:
+ * gtkruler.h:
+ * gtkhruler.c:
+ * gtkhruler.h:
+ * gtkvruler.c:
+ * gtkvruler.h: Started conversion of the ruler widget.
+
+ * gtktext.c:
+ * gtktext.h: Started conversion of the text widget. Scrolling
+ doesn't work.
+
+ * gtkmain.c: Fixed a fairly major bug. The event widget needs to
+ be in a call for the entire duration of handling an event. Not
+ just for when the event widget itself is handling the event.
+
+ * gtkfilesel.c: Fixed up some bugs with resizing.
+
+Fri Jan 10 14:18:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c:
+ * gtkwidget.h:
+ * gtkentry.c:
+ * gtkentry.h: Support for selections.
+
+ * gdkselection.c:
+ * gdk.c:
+ * gdktypes.h:
+ * gdk.h: Gdk support for X selections. Currently only text
+ selections are supported.
+
+ * gtksignal.c: Fixed a major bug which occurred when destroying an
+ object. Memory was being written to after it was freed.
+
+ * gtkfilesel.c:
+ * gtkfilesel.h: Hooked up more functionality to the file selection
+ dialog.
+
+Wed Jan 8 18:13:53 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkfilesel.c:
+ * gtkfilesel.h: Mostly converted old file selection dialog
+ widget. The widget is derived from the GtkWindow class and is
+ quite a bit simpler in the widget code.
+
+ * gtkwidget.c: Fixed 'gtk_widget_grab_focus' and
+ 'gtk_widget_grab_default' to check that the toplevel widget is a
+ type of window (which includes classes derived from windows).
+
+Tue Jan 7 01:12:32 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: Was calling 'gtk_window_resize' twice in a
+ row...why?
+
+ * gtksignal.c:
+ * gtksignal.h:
+ * *.c: Changed 'gtk_signal_new' so that the class function that is
+ called when the signal is emitted can be called either before,
+ after or both before and after the calling of any signal
+ handlers.
+
+ * gtkobject.c:
+ * gtkobject.h: Added 'object_data' mechanism for storing data
+ associated with a character string key in objects. Removed
+ 'user_data' field of objects and changed
+ 'gtk_object_{get,set}_user_data' to use the object data
+ mechanism. Removed 'handlers' field of objects.
+
+ * gtkwidget.c:
+ * gtkwidget.h:
+ * gtkwindow.c: Modified aux info mechanism to use object data
+ mechanism.
+
+ * gtksignal.c: Modified signal mechanism to use object data
+ mechanism instead of 'handlers' field.
+
+
+Mon Jan 6 15:10:16 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c: Fixed up button press handling so as to conform
+ more closely to that used by Motif.
+
+Wed Jan 1 21:27:17 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenu.c:
+ * gtkmenu.h:
+ * gtkmenubar.c:
+ * gtkmenubar.h:
+ * gtkmenushell.c:
+ * gtkmenushell.h: Reorganization of menu-ing code so that code
+ duplication is reduced. The menu shell now contains most of the
+ code for menu-ing interaction while menus and menubars simply layout
+ their child menu items in the appropriate place.
+
+Sun Dec 29 17:48:18 1996 Peter Mattis <pmattis@localhost>
+
+ * gtkmenu.c:
+ * gtkmenubar.c:
+ * gtkmenuitem.h:
+ * gtkmenuitem.c: Modifications so that menu item accelerators and
+ the submenu indicator are drawn correctly and the correct amount
+ of space is allocated.
+
+Sat Dec 28 00:32:13 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkmenufactory.h:
+ * gtkmenufactory.c: Started menu factories as an easy method to
+ create and manipulate menus.
+
+Fri Dec 27 13:17:34 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkmenu.c:
+ * gtkmenu.h:
+ * gtkmenubar.c:
+ * gtkmenubar.h:
+ * gtkmenuitem.c:
+ * gtkmenuitem.h:
+ * gtkmenushell.c:
+ * gtkmenushell.h: Implemented basic menu functionality. Menubars
+ and popup menus work. Submenus work. (Much left to be done).
+
+Wed Dec 18 15:27:05 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtktypeutils.h:
+ * gtktypeutils.c: Added 'gtk_type_from_name' which returns a type
+ identifier given a type name. Implemented using a second hash
+ table keyed by type names.
+
+ * gtkbutton.c:
+ * gtktogglebutton.c: Fixed very small messed-up drawing bug when a
+ button loses its focus.
+
+ * gtkwidget.h:
+ * gtkwidget.c:
+ * gtkbutton.c:
+ * gtkwindow.c: Added default button handling. Default buttons now
+ draw correctly and pressing return or enter causes the default
+ button (if one exists) to be activated.
+
+Tue Dec 17 19:32:21 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkhscale.c:
+ * gtkvscale.c: Overrode 'draw_slider' method of ranges in order to
+ draw the slider of scales with a line in them so as to be closer
+ to the Motif look-and-feel.
+
+ * gtkwindow.c: Modified 'gtk_window_focus_in_event' so that focus
+ in events are only handled when the window is visible. Fixes a bug
+ where spurious focus in events get sent when a window is being
+ hidden.
+
+ * gtkwidget.h: Added 'activate_signal' field to the GtkWidgetClass
+ structure. Added 'gtk_widget_activate' call to emit the activate
+ signal for a widget if it is non-zero.
+
+Tue Dec 10 15:59:45 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkwidget.c: 'gtk_widget_set_name' oops in strdup'ing the old
+ "widget->name" instead of the new one we are setting.
+
+ * gtkrc.c: 'gtk_rc_widget_path' changed to use
+ 'gtk_widget_get_name' instead of accessing the "widget->name"
+ field directly.
+
+ * gtkwidget.c: Added 'gtk_widget_get_name' function which returns
+ the widgets name if it exists and the widgets type name if it does
+ not.
+
+ * gtkcheckbutton.c: Added 'gtk_check_button_draw'
+ function. Modified 'gtk_check_button_expose' to pass an expose
+ event to child instead of callings its draw function.
+
+ * gtkentry.c: 'gtk_entry_draw_text' why was "+1" being added to
+ the font->ascent to calculate the font position? This was wrong
+ and caused some characters in fonts to be clipped. (Notably "g").
+
+ * gtkentry.c: 'gtk_entry_realize' specify GTK_BUTTON1_MOTION_MASK
+ and GTK_POINTER_MOTION_HINT_MASK for _both_ windows.
+
+ * gtkmain.c: 'gtk_propagate_event' needs to set the GTK_IN_CALL
+ flag for the object before calling 'gtk_widget_event' and needs to
+ destroy the object if necessary after 'gtk_widget_event' returns.
+
+ * gtkradiobutton.c: 'gtk_radio_button_clicked' needs to call
+ 'gtk_toggle_button_toggled' when the currently active button is
+ toggled.
+
+ * gtkwidget.c: 'gtk_real_widget_hide' needs to call
+ 'gtk_widget_unmap' if the widget is currently mapped.
+
+ * gtkwindow.c: Prevent automatic resizing after the user has
+ specified a new window size. Add 'handling_resize' flag to
+ windows.
+
+ * gtkscrolledwindow.c: Implement the GTK_POLICY_AUTOMATIC
+ scrollbar policy. Need to connect to the adjustments 'changed'
+ signal and notice when the scrollbars aren't in use.
+
+ * gtkcontainer.c: 'gtk_container_init' must set 'auto_resize' and
+ 'need_resize' fields to TRUE and FALSE respectively.
+
+ * gtkwidget.c: 'gtk_widget_set_parent' must all set a widgets state
+ to its parents state.
+
+Sun Dec 1 01:31:01 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * Started ChangeLog
--- /dev/null

+ * gtkviewport.c: Raph's Mon, 10 Nov 1997 patch to gtk-list
+ to fix some viewport bugs
+
+Mon Nov 17 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtkwidget.c: gtk-ajaborsk-971016-2
+ A little patch again to prevent user to use gtk_widget_set_events()
+ when a widget is already realized.
+ In this case, the gtk_widget_set_events() doesn't work.
+
+Mon Nov 17 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtkwindow.c: gtk-ajaborsk-971016-1
+ This small patch correct position for GTK_WIN_POS_CENTER and
+ GTK_WIN_POS_MOUSE GtkWindow positions.
+
+Sat Nov 15 1997 Jay Painter <jpaint@serv.net>
+ * gdk/gdkgc.c: added function gdk_gc_set_clip_rectangle
+ * gdk/gdk.h: header for above
+
+Sat Nov 15 1997 Jay Painter <jpaint@serv.net>
+ * gdk/gdkgc.c: added function gdk_gc_set_clip_rectangle

+Wed Nov 12 1997 Jay Painter <jpaint@serv.net>
+ * gdk/gdkpixmap.c: Patrice Fortier's patch for transparent pixmaps.
+ * gdk/gdk.h:
+ gdk/gdkdraw.c: Patrice Fortier's patch to add pixel draw function.
+
+Sun Nov 9 1997 Jay Painter <jpaint@serv.net>
+ * Fixed problems with makefiles relating to the bug
+ which required glib to be installed.
+ * Fixed makefiles to incluce the xpm's in gtk+/gtk needed
+ for testgtk.
+ * Updated gtk+ and gtk+/glib to libtool-1.0f
+
+Fri Nov 7 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtktext.c: return char_widths[ch & 0xff]; in line 2152
+
+Thr Nov 5 1997 Jay Painter <jpaint@serv.net>
+ * gtk/testgtk.c: added drag and drop test, removed the test hack
+ from the button test
+
+Tue Nov 4 08:28:57 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gtk/gtkmain.c (gtk_handle_idle): Patch from David Mosberger to
+ avoid crashes when handling idle function (this manifested itself
+ in the Umax and Microtek backends in SANE.
+
+Sun Nov 2 07:34:56 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtkfilesel.c: Small fixes about a segmentation viaolation
+ cause by a double click in the directoy list (introduced by my
+ previous changes).
+
+ * gtk/gtklist.c: Small fixes to gtk_list_add() and gtk_list_remove().
+
+ * gtk/testgtk.c (list_add): Applied Stefan Wille's patch to make this
+ function do something ;).
+
+Fri Oct 31 Jay Painter <jpaint@serv.net>
+ *gdk/gdk.c: reformatted DND code for GTK coding standards
+ *gdk/gdkwindow.c: changed memory allocation for DND to q_mem stuff
+
+Thu Oct 30 Jay Painter <jpaint@serv.net>
+ * gdk/gdkwindow.c:
+ * gdk/gdk/gdk.h:
+ * gtk/gtkwidget.h:

+
+ * gdk/gdkwindow:
+ * gdk/gdk.h:
+ * gtk/gtkwidget.h:
+ * gtk/gtkwidget.c: reformatted the DND code to conform to GTK
+ coding standards
+
+ * gtk/testgtk: massive fixes, SW's shaped window example
+
+Thu Oct 30 07:33:27 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtklistitem.c (gtk_real_list_item_toggle): applied Johannes
+ Keukelaar's <johannes@nada.kth.se> patch for keyboard support in
+ GtkList widgets.
+
+ * gtk/gtkfilesel.c: adapted dir and file list selection
+ behaviour to deal with keyboard selections. this is a little
+ bit tricky: in the dir list it just changes the entrys value on a one
+ button press. but on a keyboard selection via gtk_widget_activate() it
+ does a new population (likewise on a double click) as this seems more
+ obvious.
+
+1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * gdk/gdkcolor.c (gdk_colormap_get_system): Initialize
+ private->ref_count.
+
+Wed Oct 22 09:47:43 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtkwindow.c (gtk_window_key_release_event): Fixed a stupid
+ bug that caused the key_release_event to be propagated twice.
+
+Sun Oct 12 11:01:43 1997 Tim Janik <timj@psynet.net>
+
+ * acconfig.h:
+ * configure.in:
+ * gdk/gdkimage.c: Added configure check for IPC_RMID_DEFERRED_RELEASE,
+ because shmat() fails after a shmctl(..., IPC_RMID,...) for OSF1 V3.2,
+ SunOS 4.1.1, 5.5, 5.5.1, 5.6, IRIX 5.2 and 6.2.
+
+Mon Oct 6 11:59:07 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gdk/gdk.c (gdk_event_translate): In line 1693, fixed typo that
+ would cause motion notify events not to be delivered.
+
+Sun Oct 5 18:15:06 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gtk/gtkrc.c (gtk_rc_parse_bg_pixmap): Changed strdup() for
+ g_strdup().
+
+Wed Sep 24 17:16:34 1997 Peter Mattis <pmattis@bjork.inktomi.com>
+
+ * configure.in: Fixed a stupid error in the test for libXext that
+ would cause it to fail if X_EXTRA_LIBS was not empty.
+
+ * gtk/gtkmain.h (gtk-timj-970919.patch):
+ * gtk/gtkmain.c (gtk-timj-970919.patch): new function
+ `gtk_idle_remove_by_data' to remove all idle callbacks that take a
+ specific piece of data as argument. (gtk_get_current_event):
+ remove idles through gtk_idle_remove_by_data.
+
+ * gtk/gtkwidget.c (gtk-timj-970919.patch):
+ (gtk_widget_destroy): remove pending idles for
+ widgets that have GTK_REDRAW_PENDING or GTK_RESIZE_PENDING and
+ GTK_ANCHORED set (only anchored widgets can have a resize queue
+ handler pending). widgets that have GTK_RESIZE_NEEDED will be removed
+ from their anchored toplevels `resize_widgets' list.
+
+ (gtk_widget_queue_draw): let the widget remember the queue handler
+ tag (through `redraw_handler_key') for later call to `gtk_idle_remove'.
+
+ (gtk_widget_queue_resize): let the widget remember the queue handler
+ tag (through `resize_handler_key') for later call to `gtk_idle_remove'.
+ corrected referencing the toplevel widget for which the handler is
+ pending. if a widget is added to the `resize_widgets' list of a
+ toplevel widget, GTK_RESIZE_NEEDED is set and it's referenced.
+
+ (gtk_real_widget_queue_resize): on the deletion of the `resize_widgets'
+ list, unset GTK_RESIZE_NEEDED and unreference the removed widgets.
+
+ * gtk/gtkwindow.c (gtk-timj-970919.patch):
+ (gtk_real_window_move_resize): move `resize_containers = NULL'
+ initialization out of if-statement.
+ while stepping through the `resize_widgets' list, unreference the
+ widgets and clear GTK_RESIZE_NEEDED. if a widget realy needs are
+ resize, they are flagged through GTK_RESIZE_NEEDED now (instead of
+ GTK_RESIZE_PENDING, as this is indicative for a pending handler).
+ added checks to provide segfaulting if a widgets parent pointer
+ is NULL (e.g. on toplevel widgets that have GTK_RESIZE_NEEDED set).
+
+Tue Sep 23 13:23:27 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gdk/gdkimage.c: Applied Tim Janik's patch to mark shm segments
+ as IPC_RMID so that they are automatically removed always.
+
+ * gdk/gdkfont.c: Removed casts from lvalues.
+
+ * gtk/gtkmain.c: Removed GTK_RETLOC_*() (which do a cast) from lvalues.
+
+ * gtk/gtkaccelerator.c (gtk_accelerator_table_remove): Added
+ "const" to the accelerator_key param to be consistent with the
+ declaration in gtkaccelerator.h. The const is not useful in this
+ case, anyway.
+
+Tue Sep 16 13:11:06 1997 Peter Mattis <pmattis@bjork.inktomi.com>
+
+ * gtkpreview.c: Andrew Logan Kieschnick's change to eliminate
+ round-off error when gamma is set to 1.0.
+
+ * gtkrange.c:
+ * gtkviewport.c: Jay Painter's changes to modify the way in which
+ viewports resize.
+
+ * gdkinput.c:
+ * gdkinputgxi.h:
+ * gdkinputxfree.h:
+ * gtk/Makefile.am:
+ * gtk.h:
+ * gtkeventbox.c:
+ * gtkeventbox.h: Owen Taylor's event box widget and fixes for X
+ input support (that I had broken).
+
+ * gdk.h:
+ * gdkwindow.c:
+ * gtksignal.h:
+ * gtksignal.c: Elliot Lee's changes to support Objective C. (id is
+ apparently a reserved word in Objective C).
+
+Sun Sep 14 22:33:15 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c (gtk_widget_queue_resize): If the toplevel container
+ is invisible we simply call "gtk_container_need_resize" on
+ it. This fixes a bug with option menus not redrawing correctly.
+
+ * gtkmenuitem.c (gtk_menu_item_enter): (gtk_menu_item_leave):
+ These functions now simply pass the event on to their parent. This
+ is necessary for menus to work properly due to the change in how
+ grabs are dealts with.
+
+ * gtkwindow.c (gtk_real_window_move_resize): Fixed a bug that
+ caused the GTK_RESIZE_PENDING flag to not be unset in some cases.
+
+Fri Sep 5 20:49:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
+
+ Bug fixes:
+
+ * Makefile.am: Added PATCHES to EXTRA_DIST.
+ * gtk/gtkpixmap.c (gtk_pixmap_new): Move the "pixmap != NULL" test
+ after the allocation of the pixmap.
+
+ To shut up the compiler:
+
+ * gtk/gtkfilesel.c (get_pwdb): Initialize home_dir.
+ * gtk/gtkmain.c (gtk_init): Replace comments around calls to
+ g_set_*_handler with "if (0)".
+ * gtk/gtkrc.c (gtk_rc_get_token): Initialize hex_number and
+ float_number.
+ * gtk/gtkwindow.c (gtk_window_key_press_event): Initialize
+ direction.
+
+ Changes to the type system in gtk/:
+
+ * Makefile.am: Added gtktypebuiltins.h to gtkinclude_HEADERS.
+ Added gtk.defs, runelisp, gentypeinfo.el and gtktypebuiltins.c to
+ EXTRA_DIST. Added rules to generate gtktypebuiltins.* from
+ gtk.defs.
+
+ * runelisp, gentypeinfo.el, gtk.defs: New files.
+
+ * gtkaccelerator.c, gtkaccelerator.h (gtk_accelerator_table_ref):
+ Return the table so that this function can be used as the `copy'
+ function for GTK_TYPE_BOXED values.
+ * gtkstyle.c, gtkstyle.h (gtk_style_ref): Likewise.
+
+ * gtkenums.h: Removed GtkArgType enum.
+
+ * gtkmain.c (gtk_init): Call gtk_type_init to initialize the type
+ system.
+
+ * gtkobject.c (gtk_object_init_type): New function to take over
+ for gtk_object_get_type. (gtk_object_get_type): Just return the
+ constant GTK_TYPE_OBJECT. (gtk_object_collect_args): Do the right
+ thing for the new GTK_TYPE_* types.
+ * gtksignal.c (gtk_params_get): Likewise.
+
+ * gtktypeutils.c: (gtk_type_init_builtin_types): New
+ function. (gtk_type_init): Call it. Also made non-static.
+ (gtk_type_unique): The allocation scheme for numerical ids has
+ changed: The low 8 bits hold the appropriate GtkFundamentalType of
+ a type, the rest is a globally unique sequence number.
+ (gtk_type_hash): Use the sequence number of a key to hash it.
+ (gtk_type_register_builtin): New function.
+
+ * gtktypeutils.h: (GtkFundamentalType): New enumeration of the
+ fundamental types. (GTK_TYPE_MAKE, GTK_FUNDAMENTAL_TYPE,
+ GTK_TYPE_SEQNO): New macros to work with the new id scheme.
+ (GtkArg): Added fields for new types and renamed old ones. GtkArg
+ should now be a mostly opaque structure, except name and type.
+ (GTK_VALUE_*): New macros to access the values of a GtkArg.
+ (GTK_RETLOC_*): New macros to access the location of a return
+ value that is contained in a GtkArg. * gtktypebuiltins.h: New
+ file to access the typeids of the builtin types.
+
+ * gtkwidget.h (GTK_TYPE_WIDGET): New macro to access the type id
+ of the widget class.
+
+ Thru out: Changed GTK_ARG_* to the appropriate GTK_TYPE_*.
+ Changed access to GtkArg structure to the appropriate GTK_VALUE_*
+ or GTK_RETLOC_* macro. Changed GtkArgType to GtkType. Changed
+ some guints to GtkType.
+
+ General changes in gtk/ to support interpreters:
+
+ * gtkradiobutton.c (gtk_radio_button_new_from_widget,
+ gtk_radio_button_new_with_label_from_widget): New functions.
+
+ * gtksignal.c (gtk_signal_connect_no_marshal): New function.
+ (struct _GtkHandler): Added no_marshal and destroy_func fields.
+ (gtk_signal_handler_new): Initialize them.
+ (gtk_signal_connect_by_type): Added no_marshal and destroy_func
+ arguments. Changed all callers.
+ (gtk_signal_destroy): Invoke destroy_func if there is one and the
+ global destroy func does not apply. (gtk_handlers_run): If the
+ handler has no_marshal set, call its function directly without
+ going thru the signal's marshaller.
+
+Wed Sep 3 09:56:22 1997 RHS Linux User <pmattis@bjork.inktomi.com>
+
+ * gtkrange.c: Changed the way the range control focus was drawn so
+ that the range control is drawn correctly when it does not have
+ the focus.
+
+Tue Sep 2 17:41:17 1997 RHS Linux User <pmattis@bjork.inktomi.com>
+
+ * gtkwidget.c: 'gtk_real_widget_queue_resize' should only remove
+ the "resize_widgets" if another resize is not pending.
+
+Mon Sep 1 18:28:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmain.c: Changed the way GDK_DELETE events are handled. Only,
+ if 'gtk_widget_event' returns TRUE is the widget destroyed. By
+ default, 'gtk_widget_event' will return FALSE causing the window
+ to not be destroyed. This prevents segfaults in the GIMP and other
+ programs that do not correctly handle GDK_DELETE events.
+
+ * gtkmain.c: Added modal dialog support by allowing events
+ destined for a child of the grab widget to go to the child instead
+ of the grab widget. (Added 'gtk_widget_is_ancestor' to determine
+ the relationship between the grab widget and the event widget).
+
+ * *.[ch]: Incorprated a whole mess of patches. (Started keeping
+ the ChangeLog up to date again).
+
+Thu Jun 5 17:22:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c:
+ * gtkmenufactory.h: Added 'gtk_menu_factory_remove_*'
+ calls. Removing entries/paths causes the associated widgets to be
+ destroyed.
+
+ * gtkwidget.c:
+ * gtkwidget.h: Calling 'gtk_widget_set_style' is used as an
+ indication that the programmer specifically wants that style to be
+ used. RC-style substitution is disabled for the widget after such
+ a call.
+
+ * gtkpixmap.c:
+ * gtkpixmap.h:
+ * gtkimage.c:
+ * gtkimage.h: Changed to use clip mask and a single pixmap (or
+ image) to deal with transparent areas.
+
+ * gdkpixmap.c: Modified xpm loading routines to optionally return
+ a clip mask.
+
+ * gdkgc.c:
+ * gdkdraw.c:
+ * gdktypes.h: Modifications to allow clip masks to be used with
+ gc's. Clip masks are bitmaps that specify drawable regions.
+
+Thu May 1 03:11:51 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkscrolledwindow.c: Scrolled windows need to have the
+ GTK_NO_WINDOW flag set. Not having it set caused an obscure
+ redrawing bug.
+
+Wed Apr 30 12:38:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkhruler.c:
+ * gtkvruler.c: Fixed a small bug that caused the indicator to be
+ positioned slightly off.
+
+Sun Apr 27 14:28:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c:
+ * gtkmenushell.h:
+ * gtkmenu.c:
+ * gtkmenu.h: Changes so that if a menu is popped up there is a
+ timeout period during which a menu item will not be activated and
+ if the mouse button is released in that period the menu will stay
+ popped up.
+
+ * gtkcurve.c:
+ * gtkcurve.h: Included curve widget courtesy of David
+ Mosberger-Tang (davidm@azstarnet.com).
+
+ * gtkentry.c:
+ * gtkentry.h: Changed "insert" and "delete" signals to
+ "insert_text" and "delete_text" respectively. (The symbol "delete"
+ cannot be used since it is a C++ reserved word).
+
+Sat Apr 19 01:43:49 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c: A path which ends in "<nothing>" will cause an
+ invisible (hidden) menu entry to be created. This is useful for
+ setting an accelerator key for which a corresponding menu entry is
+ not desired.
+
+ * gtktooltips.c: Fixed some problems with destruction of the
+ active tip widget not properly updating the tooltips data
+ structures.
+
+Fri Apr 18 15:09:45 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcontainer.c:
+ * gtklist.c:
+ * gtkwidget.c:
+ * gtkwidget.h: Patch from Owen Taylor (owt1@cornell.edu) which
+ fixes problems with destruction of objects and with destruction of
+ objects which hold the focus.
+
+Thu Apr 17 11:29:15 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c: Incorrect logic in
+ 'gtk_menu_shell_button_release' for deciding when a menu should
+ stay popped up when the mouse button is released.
+
+ * *.c: Miscellaneous fixes from folks on the net.
+
+Tue Apr 15 02:43:17 1997 Peter Mattis <pmattis@localhost>
+
+ * *.c:
+ * gtkwidget.h: Added GTK_BASIC widget flag which when set
+ specifies a widget as "basic". A "basic" widget is one which
+ doesn't take input events. For example, labels, pixmaps, boxes,
+ tables, alignments, etc.
+
+Sat Apr 12 15:23:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcolorsel.c: Add "#include <math.h>" to define M_PI.
+
+ * gtksignal.c: Fixed a bug in 'gtk_signal_emit' which showed up
+ because of the new cast checking macros. The 'object' was being
+ accessed after it had been destroyed.
+
+ * gtkoptionmenu.c: Fixed bug with using 'GTK_BIN' instead of
+ 'GTK_BUTTON' which showed up because of the new cast checking
+ macros.
+
+ * *.h: 'GTK_CHECK_CAST', 'GTK_CHECK_CLASS_CAST' and
+ 'GTK_CHECK_TYPE' used by standard widget macros everywhere.
+
+Wed Apr 9 00:54:17 1997 Peter Mattis <pmattis@localhost>
+
+ * docs/gtk.texi: Started further work on documentation. Major
+ changes and additions are being made.
+
+ * gtkarrow.c:
+ * gtkarrow.h: Removed function 'gtk_arrow_get'.
+
+ * gtkcontainer.c: 'gtk_container_check_resize' no performs
+ additional checking to account for the case where the containers
+ allocation is no longer sufficient because its parent (or its
+ parents parent, etc.) needs to resize its children.
+
+Tue Apr 8 21:15:50 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkstyle.c: Fixed a bug in 'gtk_style_init' in which the font
+ was not ref'd (via 'gdk_font_ref'), but was free'd (via in
+ 'gdk_font_free') in 'gtk_style_destroy'. (David
+ Mosberger-Tang). Also cleaned up 'gtk_style_destroy' while I was
+ at it.
+
+ * gtkmain.c: Fixed a bug in 'gtk_propogate_event' which caused
+ entry widgets (and probably other widgets) not to be destroyed in
+ some instances.
+
+Mon Apr 7 01:20:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkentry.c:
+ * gtkentry.h: Changed the "insert_text", "delete_text" and
+ "changed_text" signals to "insert", "delete", and "changed"
+ respectively. They really should have been named this way
+ originally except the previous signal mechanism prevented
+ duplicate signal names. ("changed" is also used by adjustments).
+
+ * gtkradiomenuitem.c:
+ * gtkradiomenuitem.h: New widget.
+
+ * gtkcheckmenuitem.c:
+ * gtkcheckmenuitem.h: New widget.
+
+ * gtksignal.c: Modified 'gtk_signal_lookup' to require an object
+ type to be passed as a parameter. In addition, signals are now
+ only needed to be uniquely defined in their branch of the class
+ hierarchy. This allows the same signal name to be used in two
+ different branches of the class hierarchy. For instance, the
+ "changed" signal is used both by adjustments and entries...in
+ different ways!
+
+ * gtktypeutils.c: Added 'gtk_type_parent' which returns the parent
+ type for a given type.
+
+Sun Apr 6 22:08:35 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c: If a widget is set insensitive it loses the focus
+ if it had it.
+
+ * gtkcontainer.c: Insensitive widgets no longer participate in tab
+ traversal.
+
+ * gtkscrolledwindow.c: The "viewport" child is now destroyed and a
+ container class "foreach" function was written (which fixes the
+ sensitivity bug).
+
+Sat Apr 5 14:25:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkhscrollbar.c:
+ * gtkvscrollbar.c: Fixed trough size allocation bug.
+
+ * gtkhscale.c:
+ * gtkvscale.c: Fixed trough size allocation and position bug that
+ showed up when scales were placed in notebooks.
+
+Thu Mar 27 17:45:54 1997 David Mosberger-Tang <davidm@azstarnet.com>
+
+ * gtk/gtkmain.c (gtk_handle_idle): Fix appending pending_idles to
+ idle_functions so it works even when idle_functions is empty.
+
+Sat Mar 15 14:15:59 1997 Peter Mattis <pmattis@localhost>
+
+ * *.[ch]: Moved '*_class_init' and '*_init' function declarations
+ for widgets into the source file as those functions no longer had
+ to be public.
+
+ * gtkcheckbutton.c: Fixed redrawing of check button.
+
+ * gtkframe.c: Fixed redrawing of frame when the shadow type is
+ changed.
+
+Sat Mar 8 15:19:23 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkimage.c: Fixed a stupid bug with 'gdk_image_new' which
+ potentially added a NULL image to "image_list" and caused problems
+ when 'gdk_image_exit' was called.
+
+Wed Mar 5 00:40:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkpreview.c: Massively changed the colormap handling used by
+ the preview widget. Gray previews are now dithered. A single
+ visual and colormap is shared by the color and gray previews. A
+ GTK_PREVIEW_INFO property is installed on the root window in
+ certain cases to allow multiple GTK programs to share the system
+ colormap.
+
+Sun Mar 2 05:43:06 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcheckbutton.c: 'gtk_checkbutton_size_allocate' was allocating
+ too much space to its children and not leaving the check button
+ room for the focus border.
+
+ * gtknotebook.c: 'gtk_notebook_size_request' wasn't requesting
+ enough space when the notebook tabs are visible.
+
+Sat Mar 1 01:59:35 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkpreview.c: Fixed a problem with 'gtk_preview_put' when the
+ image byte order is GDK_MSB_FIRST.
+
+ * gtksignal.c:
+ * gtksignal.h: Added 'gtk_signal_connect_after' and
+ 'gtk_signal_connect_object_after' functions. These connect signal
+ handlers which will run after the class function associated with
+ the signal.
+
+ * gtkstyle.c: Fixed a stupid bug in 'gtk_style_new_from_key' that
+ was causing twice as many styles to be created as necesary.
+
+ * gtkwidget.c: 'gtk_real_widget_size_allocate' erases the widgets
+ old allocation if it has the GTK_NO_WINDOW flag set.
+
+ * gtkwidget.c: 'gtk_real_widget_unmap' now erases the widget if it
+ has the GTK_NO_WINDOW flag set.
+
+ * gtklabel.c: Removed 'gtk_label_unmap' as similar functionality
+ was added to gtk_real_widget_unmap.
+
+ * gtkbin.c: Modified 'gtk_bin_map' and 'gtk_bin_unmap' so that it
+ erases and draws the widget if it has the GTK_NO_WINDOW flag set.
+
+ * gtkframe.c: Modified 'gtk_frame_size_allocate' so that it erases
+ the old allocation.
+
+Fri Feb 28 03:27:05 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: 'gtk_window_set_title' now changes the window title
+ if the window is already realized.
+
+ * gtkentry.c: 'gtk_entry_set_text' was emitting both a
+ "delete_text" and a "changed_text" signal. Modified so that it
+ only emits a "changed_text" signal.
+
+ * gtkpreview.c: Modified to work correctly on systems with MSB
+ byte order. The colormap for TRUE and DIRECT color displays is now
+ created if the default visual is not equal to the visual we are
+ using.
+
+ * gtkstyle.c: 'gtk_style_attach' and 'gtk_style_find' weren't
+ working properly in the presence of multiple colormaps are
+ different depth visuals.
+
+ * gtkcontainer.c: Massively improved focus traversal using tab and
+ arrow keys. It now uses the layout of the widgets to determine
+ where to move the focus to.
+
+Mon Feb 24 03:24:02 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c: Set the accelerator table field for menus when
+ they are created.
+
+ * gtkmenu.c:
+ * gtkmenu.h: Added a default accelerator table field to menus so
+ that runtime modification of accelerator keys in menus can work
+ better.
+
+ * gtkrange.c: 'gtk_range_default_{h,v}motion' had faulty logic for
+ deciding what to do when the slider was at the edge of the
+ trough. They previously didn't update the adjustment value event
+ if the value wasn't what it should be when the slider was at the
+ edge of the trough.
+
+ * gtkviewport.c: 'gtk_viewport_size_allocate' and
+ 'gtk_viewport_adjustment_value_changed' both had the potential for
+ performing a divide by 0. Checks are now in place to prevent this.
+
+ * gtkmenu.c: 'gtk_menu_map' now makes sure the menu lies on screen
+ if the position function is NULL.
+
+ * gtkentry.c: Modified selection handling. 'gtk_delete_selection'
+ actually removes the X selection now. 'gtk_entry_destroy' removes
+ the selection as well and relies on the change in "gdk.c" to make
+ sure the selection event will not be sent to a non-existant
+ window.
+
+ * gdk.c: Selection events are only passed on if the selection
+ owner is not NULL.
+
+ * gtkstyle.c: 'gtk_style_detach' and 'gtk_style_destroy' were not
+ destroying the black and white gc's.
+
+Sun Feb 23 19:17:56 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: 'gtk_window_size_request' was setting the window
+ hints. This was also being done in 'gtk_window_map', so the
+ instance being done in 'gtk_window_size_request' was removed.
+
+Fri Feb 21 01:04:01 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c: 'gtk_widget_draw' has to use the widgets allocated
+ position for the drawing rectangle when the widget has the
+ GTK_NO_WINDOW flag set.
+
+ * gtkwidget.c: In 'gtk_widget_init' the visual and colormap were
+ being directly compared against 'default_visual' and
+ 'default_colormap' instead of calling
+ 'gtk_widget_get_default_{visual,colormap}'.
+
+ * gdkrectangle.c: Amazing! There was a bug in the
+ 'gtk_rectangle_intersect' logic. Its been there for near eternity
+ and I never noticed.
+
+ * gtkpreview.c:
+ * gtkpreview.h: Created preview widget which allows drawing to an
+ rgb or grayscale buffer which is automatically displayed on the
+ screen. Performs dithering as necessary.
+
+Thu Feb 20 20:33:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkwindow.c: Modified the logic in 'gdk_window_new' which
+ determined when to add a window to the WM_COLORMAP_WINDOWS
+ property.
+
+Wed Feb 19 19:55:29 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkruler.c: 'gtk_ruler_make_pixmap' was always destroying the
+ old backing store and creating a new one even when it would create
+ a new one of exactly the same size as the old one.
+
+Tue Feb 18 18:32:10 1997 Peter Mattis <pmattis@localhost>
+
+ * gmem.c: 'g_mem_chunk_alloc' was incorrectly modifying the mem
+ areas free mem field when reallocating a previously freed
+ atom. This caused a fairly severe memory leak.
+
+ * gtkmenushell.c: 'gtk_menu_shell_button_release' had a bug in the
+ logic for deciding whether to initiate an X pointer grab or not
+ when the mouse button was released. It now only initiates a grab
+ if the mouse is released within an active menu item.
+
+Fri Feb 14 00:57:40 1997 Peter Mattis <pmattis@localhost>
+
+ * gtknotebook.c: Changed the look of notebook tabs slightly.
+
+ * gtkentry.c:
+ * gtkentry.h: Deleting an entry widget which is holding the X
+ selection presents some difficulties. The X selection must be
+ released, but the widget can't be destroyed until the
+ SELECTION_CLEAR event is received that the X server will send in
+ response to clearing the X selection. There are probably still
+ bugs in the current method of entry widget deletion when the X
+ selection is held.
+
+ * gtkmain.c: 'gtk_propagate_event' was not properly destroying the
+ toplevel window when receiving a key press event.
+
+ * gtkwidget.c: Setting a widget insensitive did not cause it to
+ redraw. It now does.
+
+Thu Feb 13 16:59:07 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkviewport.c: 'gtk_viewport_size_allocate' was allocating its
+ child widget an adjusted allocation. Since the actual scrolling
+ has handled by a subwindow this caused the child to be double
+ scrolled. Modified to always set the child allocations origin to
+ (0, 0).
+
+Wed Feb 12 01:06:48 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkentry.c: Text is now centered vertically. Previously it was
+ pushed up against the top. This problem was only evident when the
+ widget was allocated more vertical space than it requested.
+
+ * gtkfilesel.c: 'gtk_file_selection_key_press' was previously only
+ a stub for tab completion. The actual tab completion call had been
+ left out. (Oops!)
+
+Tue Feb 11 01:43:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtksignal.c: 'gtk_signal_disconnect_by_data' was going into a
+ loop and crashing. Bad logic. Fixed.
+
+ * gtkmain.c: An idle function which returns FALSE will be removed
+ from the list of idle functions. This makes the functioning of
+ idle functions and timeouts more similar.
+
+ * gtkentry.c: 'gtk_entry_get_text' now returns an empty string
+ when the actual text is NULL. This allows "stupid" programs to use
+ the value returned by 'gtk_entry_get_text' blindly (without
+ checking to see if its NULL).
+
+ * gtkradiobutton.c: Modified 'gtk_radio_button_clicked' so that
+ 'gtk_toggle_button_toggled' is called _after_ the widget state is
+ changed.
+
+ * gtksignal.c:
+ * gtksignal.h: Added 'gtk_signal_name' which returns the character
+ string name for a given signal number.
+
+ * gtkwidget.c: 'gtk_widget_set_parent' checks to see if the widget
+ is now "anchored" through the parent chain to a widget which is
+ GTK_ANCHORED. If it is, then it changes the widgets style using
+ 'gtk_rc_get_style' and recursively performs the same operation on
+ the widgets children. This is necessary is 'gtk_rc_get_style' only
+ works properly on "anchored" widgets.
+
+ * gtkwindow.c: Modified GTK_WIN_POS logic so that it is only used
+ immediately after the window has been shown.
+
+ * gtkmenu.c: 'gtk_menu_key_press'. Can now change menu item
+ accelerator keys on the fly. Why? Why not. Cool/useless feature of
+ the day.
+
+ * gtkmenuitem.c: Accelerator key drawing. Somehow that never got
+ finished. (Oops!)
+
+ * gtkdrawingarea.c: 'gtk_drawing_area_size_allocate' was not
+ actually installed during 'gtk_drawing_area_class_init'. (Oops!)
+
+ * gtkframe.c: 'gtk_frame_size_request' fixed size requisition
+ problem caused by unsigned arithmetic.
+
+ * gtkwindow.c: Modified window widget so that it only uses the
+ widget uposition auxiliary information immediately after it has
+ been shown. This prevents the annoying bug which can cause a
+ uposition'ed window to jump back to its original position after
+ the user moves it.
+
+ * gtkwidget.c: Need to ref and unref style in
+ 'gtk_widget_{push,pop}_style' to make sure that a style on the
+ style stack is not destroyed.
+
+ * gtktogglebutton.c: 'gtk_toggle_button_set_state' now calls
+ gtk_button_clicked to actually change the state of the
+ button. In this way, radio buttons can now perform the appropriate
+ actions when the toggle button state is set.
+
+Mon Feb 10 00:27:39 1997 Peter Mattis <pmattis@localhost>
+
+ * gtklist.c: 'gtk_list_select_item' and 'gtk_list_unselect_item'
+ were casting a GList* variable to a a GtkWidget* variable. Bad bad
+ bad. (Tim Janik).
+
+ * gtksignal.c: Modified 'gtk_signal_connect' and
+ 'gtk_signal_connect_object' to warn when a signal type cannot be
+ found.
+
+Sun Feb 9 00:15:30 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkoptionmenu.c:
+ * gtkoptionmenu.h: Changed option menus back to being derived from
+ buttons. This fixes up some screwiness with their user
+ interaction.
+
+ * gtkwindow.c: Modified key press handler to support focus
+ traversal.
+
+ * gtkcontainer.c:
+ * gtkcontainer.h: Added default focus traversal back in.
+
+Sat Feb 8 10:44:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkviewport.h:
+ * gtkviewport.c: Massively sped up viewport scrolling. Used to be
+ reallocating child's size (offset) each time a scrollbar
+ moved. Now a subwindow is moved. All the children are moved
+ automatically by moving the subwindow. Much much much faster.
+
+Tue Feb 4 00:20:44 1997 Peter Mattis <pmattis@localhost>
+
+ * gtree.c: Changed 'g_tree_node_search' to use a loop instead of
+ recursion.
+
+Mon Feb 3 11:30:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkbutton.c: Removed 'parent_destroy' global and replaced it
+ with 'parent_class' global to reflect style used in other
+ widgets.
+
+ * gtknotebook.c: Tab labels were being allocated less than their
+ requested size.
+
+ * gtkrange.c:
+ * gtkrange.h: Moved the "digits" field of scales into the range
+ type. The adjustment value for scales is truncated to the number
+ of visible digits instead of being left untouched.
+
+ * gtree.c: Fixed a bug in the AVL tree implementation. Single
+ rotations were always being performed during insertion. It is
+ sometimes necessary to perform a double rotation.
+
+ * gtklabel.c: Modified 'gtk_label_expose' to only draw the label
+ when the allocated space is greater than or equal to the requested
+ space.
+
+ * gtklabel.c: Added call to 'gtk_widget_unmap' to
+ 'gtk_label_destroy' in order for the label to redraw correctly
+ (erase itself) when destroyed.
+
+ * gtklabel.c: Added 'gtk_label_unmap' call which erases the labels
+ allocation when it gets unmapped.
+
+ * *.h: Removed a few remaining instances of using "class" as a
+ parameter name. (Causes problems for C++).
+
+Fri Jan 31 12:26:50 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcontainer.c: 'gtk_container_enable_resize' needs to call
+ 'gtk_container_check_resize' instead of
+ 'gtk_container_need_resize'.
+
+ * gtkwidget.c: 'gtk_real_widget_show' now maps the widget if its
+ parent is mapped.
+
+ * gtkscrolledwindow.c: Fixed size allocation when the scrollbar
+ policy's are GTK_POLICY_AUTOMATIC. Doing it correctly is harder
+ than I originally thought.
+
+ * gtklist.c: Added 'gtk_list_child_position' to determine the
+ integer position in a list of a child. Filled in the
+ 'gtk_list_item_select' and 'gtk_list_item_unselect' stubs.
+
+Thu Jan 30 16:08:06 1997 Peter Mattis <pmattis@localhost>
+
+ * gmem.c: Changed the implementation of G_ALLOC_AND_FREE mem
+ chunks. They used to allocate SIZEOF_VOID_P extra bytes per atom
+ in order to keep track of which mem area they were allocated
+ from. Now the mem area is determined by searching through an AVL
+ tree of the mem areas for a mem chunk and comparing memory
+ locations. A little slower, but makes G_ALLOC_AND_FREE mem chunks
+ much more attractive.
+
+ * gtree.c: Added an AVL tree implementation to glib.
+
+ * gtksignal.c:
+ * gstring.c: va_arg (arg_list, {char, short}) is
+ invalid. Arguments passed in a variable argument list are
+ promoted. ({char, short}->int). Seemed to work ok before under
+ Linux. Crashed under FreeBSD.
+
+Tue Jan 28 02:27:51 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkwindow.c: Fixed a major slowdown apparent in the file
+ selection dialog which was caused by calling
+ 'gtk_window_add_colormap_windows' way way way too often.
+
+ * *.c: Many widgets called 'gtk_container_need_resize' when
+ something internal changed which would cause the widget to grow or
+ shrink. The assumption was made that the widget would change size
+ and an expose event would be generated. This happens "most" of the
+ time. But its possible for certain widgets to change size without
+ generating expose events, or for its internal geometry to change
+ without a change of size which would mean no expose event was
+ generated. So a wrapper function called
+ 'gtk_container_check_resize' was created and
+ 'gtk_container_need_resize' was modified so that it returns FALSE
+ if a resize was actually generated and TRUE if nothing
+ changed. This allows 'gtk_container_check_resize' to initiate a
+ 'gtk_widget_size_allocate' and 'gtk_widget_draw' to emulate the
+ expose event.
+
+Sat Jan 25 14:17:44 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmain.c: Fixed a bug with propogating key press events. The
+ events were sent 2 times to the toplevel windows which caused the
+ focus widget to be activated twice when the space bar was pressed.
+
+ * */configure.in:
+ * */Makefile.am: Added support for libtool and removed the old
+ shared library configuration craziness.
+
+Fri Jan 24 12:59:22 1997 Peter Mattis <pmattis@localhost>
+
+ * gtktext.c:
+ * gtktext.h: Josh's fixes and additions to the text widget.
+
+ * gtkfill.c:
+ * gtkfill.h: Filler widget useful for filling space in a
+ table. Can specify a minimum size. Used by the canvas widget.
+
+ * gtknotebook.c:
+ * gtknotebook.h: Made outline of notebook widget.
+
+ * gtkcanvas.c:
+ * gtkcanvas.h: Started canvas widget. A composite of 2 rulers (w/
+ an origin), 2 scrolllbars. Guides, grids, snap to.
+
+Sun Jan 19 18:26:45 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkdialog.c:
+ * gtkdialog.h: Created dialog widget which creates a standard
+ looking dialog with buttons along the button and a separator.
+
+ * gtkxid.c: Generalized the window table code for looking up a gdk
+ window based on an XID to work for any XID and a piece of
+ data. Can now look up gdk fonts based on their XID.
+
+ * gtkruler.c:
+ * gtkruler.h:
+ * gtkhruler.c:
+ * gtkhruler.h:
+ * gtkvruler.c:
+ * gtkvruler.h: Started conversion of the ruler widget.
+
+ * gtktext.c:
+ * gtktext.h: Started conversion of the text widget. Scrolling
+ doesn't work.
+
+ * gtkmain.c: Fixed a fairly major bug. The event widget needs to
+ be in a call for the entire duration of handling an event. Not
+ just for when the event widget itself is handling the event.
+
+ * gtkfilesel.c: Fixed up some bugs with resizing.
+
+Fri Jan 10 14:18:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c:
+ * gtkwidget.h:
+ * gtkentry.c:
+ * gtkentry.h: Support for selections.
+
+ * gdkselection.c:
+ * gdk.c:
+ * gdktypes.h:
+ * gdk.h: Gdk support for X selections. Currently only text
+ selections are supported.
+
+ * gtksignal.c: Fixed a major bug which occurred when destroying an
+ object. Memory was being written to after it was freed.
+
+ * gtkfilesel.c:
+ * gtkfilesel.h: Hooked up more functionality to the file selection
+ dialog.
+
+Wed Jan 8 18:13:53 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkfilesel.c:
+ * gtkfilesel.h: Mostly converted old file selection dialog
+ widget. The widget is derived from the GtkWindow class and is
+ quite a bit simpler in the widget code.
+
+ * gtkwidget.c: Fixed 'gtk_widget_grab_focus' and
+ 'gtk_widget_grab_default' to check that the toplevel widget is a
+ type of window (which includes classes derived from windows).
+
+Tue Jan 7 01:12:32 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: Was calling 'gtk_window_resize' twice in a
+ row...why?
+
+ * gtksignal.c:
+ * gtksignal.h:
+ * *.c: Changed 'gtk_signal_new' so that the class function that is
+ called when the signal is emitted can be called either before,
+ after or both before and after the calling of any signal
+ handlers.
+
+ * gtkobject.c:
+ * gtkobject.h: Added 'object_data' mechanism for storing data
+ associated with a character string key in objects. Removed
+ 'user_data' field of objects and changed
+ 'gtk_object_{get,set}_user_data' to use the object data
+ mechanism. Removed 'handlers' field of objects.
+
+ * gtkwidget.c:
+ * gtkwidget.h:
+ * gtkwindow.c: Modified aux info mechanism to use object data
+ mechanism.
+
+ * gtksignal.c: Modified signal mechanism to use object data
+ mechanism instead of 'handlers' field.
+
+
+Mon Jan 6 15:10:16 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c: Fixed up button press handling so as to conform
+ more closely to that used by Motif.
+
+Wed Jan 1 21:27:17 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenu.c:
+ * gtkmenu.h:
+ * gtkmenubar.c:
+ * gtkmenubar.h:
+ * gtkmenushell.c:
+ * gtkmenushell.h: Reorganization of menu-ing code so that code
+ duplication is reduced. The menu shell now contains most of the
+ code for menu-ing interaction while menus and menubars simply layout
+ their child menu items in the appropriate place.
+
+Sun Dec 29 17:48:18 1996 Peter Mattis <pmattis@localhost>
+
+ * gtkmenu.c:
+ * gtkmenubar.c:
+ * gtkmenuitem.h:
+ * gtkmenuitem.c: Modifications so that menu item accelerators and
+ the submenu indicator are drawn correctly and the correct amount
+ of space is allocated.
+
+Sat Dec 28 00:32:13 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkmenufactory.h:
+ * gtkmenufactory.c: Started menu factories as an easy method to
+ create and manipulate menus.
+
+Fri Dec 27 13:17:34 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkmenu.c:
+ * gtkmenu.h:
+ * gtkmenubar.c:
+ * gtkmenubar.h:
+ * gtkmenuitem.c:
+ * gtkmenuitem.h:
+ * gtkmenushell.c:
+ * gtkmenushell.h: Implemented basic menu functionality. Menubars
+ and popup menus work. Submenus work. (Much left to be done).
+
+Wed Dec 18 15:27:05 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtktypeutils.h:
+ * gtktypeutils.c: Added 'gtk_type_from_name' which returns a type
+ identifier given a type name. Implemented using a second hash
+ table keyed by type names.
+
+ * gtkbutton.c:
+ * gtktogglebutton.c: Fixed very small messed-up drawing bug when a
+ button loses its focus.
+
+ * gtkwidget.h:
+ * gtkwidget.c:
+ * gtkbutton.c:
+ * gtkwindow.c: Added default button handling. Default buttons now
+ draw correctly and pressing return or enter causes the default
+ button (if one exists) to be activated.
+
+Tue Dec 17 19:32:21 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkhscale.c:
+ * gtkvscale.c: Overrode 'draw_slider' method of ranges in order to
+ draw the slider of scales with a line in them so as to be closer
+ to the Motif look-and-feel.
+
+ * gtkwindow.c: Modified 'gtk_window_focus_in_event' so that focus
+ in events are only handled when the window is visible. Fixes a bug
+ where spurious focus in events get sent when a window is being
+ hidden.
+
+ * gtkwidget.h: Added 'activate_signal' field to the GtkWidgetClass
+ structure. Added 'gtk_widget_activate' call to emit the activate
+ signal for a widget if it is non-zero.
+
+Tue Dec 10 15:59:45 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkwidget.c: 'gtk_widget_set_name' oops in strdup'ing the old
+ "widget->name" instead of the new one we are setting.
+
+ * gtkrc.c: 'gtk_rc_widget_path' changed to use
+ 'gtk_widget_get_name' instead of accessing the "widget->name"
+ field directly.
+
+ * gtkwidget.c: Added 'gtk_widget_get_name' function which returns
+ the widgets name if it exists and the widgets type name if it does
+ not.
+
+ * gtkcheckbutton.c: Added 'gtk_check_button_draw'
+ function. Modified 'gtk_check_button_expose' to pass an expose
+ event to child instead of callings its draw function.
+
+ * gtkentry.c: 'gtk_entry_draw_text' why was "+1" being added to
+ the font->ascent to calculate the font position? This was wrong
+ and caused some characters in fonts to be clipped. (Notably "g").
+
+ * gtkentry.c: 'gtk_entry_realize' specify GTK_BUTTON1_MOTION_MASK
+ and GTK_POINTER_MOTION_HINT_MASK for _both_ windows.
+
+ * gtkmain.c: 'gtk_propagate_event' needs to set the GTK_IN_CALL
+ flag for the object before calling 'gtk_widget_event' and needs to
+ destroy the object if necessary after 'gtk_widget_event' returns.
+
+ * gtkradiobutton.c: 'gtk_radio_button_clicked' needs to call
+ 'gtk_toggle_button_toggled' when the currently active button is
+ toggled.
+
+ * gtkwidget.c: 'gtk_real_widget_hide' needs to call
+ 'gtk_widget_unmap' if the widget is currently mapped.
+
+ * gtkwindow.c: Prevent automatic resizing after the user has
+ specified a new window size. Add 'handling_resize' flag to
+ windows.
+
+ * gtkscrolledwindow.c: Implement the GTK_POLICY_AUTOMATIC
+ scrollbar policy. Need to connect to the adjustments 'changed'
+ signal and notice when the scrollbars aren't in use.
+
+ * gtkcontainer.c: 'gtk_container_init' must set 'auto_resize' and
+ 'need_resize' fields to TRUE and FALSE respectively.
+
+ * gtkwidget.c: 'gtk_widget_set_parent' must all set a widgets state
+ to its parents state.
+
+Sun Dec 1 01:31:01 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * Started ChangeLog
--- /dev/null

+ * gtkviewport.c: Raph's Mon, 10 Nov 1997 patch to gtk-list
+ to fix some viewport bugs
+
+Mon Nov 17 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtkwidget.c: gtk-ajaborsk-971016-2
+ A little patch again to prevent user to use gtk_widget_set_events()
+ when a widget is already realized.
+ In this case, the gtk_widget_set_events() doesn't work.
+
+Mon Nov 17 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtkwindow.c: gtk-ajaborsk-971016-1
+ This small patch correct position for GTK_WIN_POS_CENTER and
+ GTK_WIN_POS_MOUSE GtkWindow positions.
+
+Sat Nov 15 1997 Jay Painter <jpaint@serv.net>
+ * gdk/gdkgc.c: added function gdk_gc_set_clip_rectangle
+ * gdk/gdk.h: header for above
+
+Sat Nov 15 1997 Jay Painter <jpaint@serv.net>
+ * gdk/gdkgc.c: added function gdk_gc_set_clip_rectangle

+Wed Nov 12 1997 Jay Painter <jpaint@serv.net>
+ * gdk/gdkpixmap.c: Patrice Fortier's patch for transparent pixmaps.
+ * gdk/gdk.h:
+ gdk/gdkdraw.c: Patrice Fortier's patch to add pixel draw function.
+
+Sun Nov 9 1997 Jay Painter <jpaint@serv.net>
+ * Fixed problems with makefiles relating to the bug
+ which required glib to be installed.
+ * Fixed makefiles to incluce the xpm's in gtk+/gtk needed
+ for testgtk.
+ * Updated gtk+ and gtk+/glib to libtool-1.0f
+
+Fri Nov 7 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtktext.c: return char_widths[ch & 0xff]; in line 2152
+
+Thr Nov 5 1997 Jay Painter <jpaint@serv.net>
+ * gtk/testgtk.c: added drag and drop test, removed the test hack
+ from the button test
+
+Tue Nov 4 08:28:57 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gtk/gtkmain.c (gtk_handle_idle): Patch from David Mosberger to
+ avoid crashes when handling idle function (this manifested itself
+ in the Umax and Microtek backends in SANE.
+
+Sun Nov 2 07:34:56 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtkfilesel.c: Small fixes about a segmentation viaolation
+ cause by a double click in the directoy list (introduced by my
+ previous changes).
+
+ * gtk/gtklist.c: Small fixes to gtk_list_add() and gtk_list_remove().
+
+ * gtk/testgtk.c (list_add): Applied Stefan Wille's patch to make this
+ function do something ;).
+
+Fri Oct 31 Jay Painter <jpaint@serv.net>
+ *gdk/gdk.c: reformatted DND code for GTK coding standards
+ *gdk/gdkwindow.c: changed memory allocation for DND to q_mem stuff
+
+Thu Oct 30 Jay Painter <jpaint@serv.net>
+ * gdk/gdkwindow.c:
+ * gdk/gdk/gdk.h:
+ * gtk/gtkwidget.h:
+ * gtk/gtkwidget.c: Applied Stephan Willie's shaped window patch
+
+ * gdk/gdkwindow:
+ * gdk/gdk.h:
+ * gtk/gtkwidget.h:
+ * gtk/gtkwidget.c: reformatted the DND code to conform to GTK
+ coding standards
+
+ * gtk/testgtk: massive fixes, SW's shaped window example
+
+Thu Oct 30 07:33:27 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtklistitem.c (gtk_real_list_item_toggle): applied Johannes
+ Keukelaar's <johannes@nada.kth.se> patch for keyboard support in
+ GtkList widgets.
+
+ * gtk/gtkfilesel.c: adapted dir and file list selection
+ behaviour to deal with keyboard selections. this is a little
+ bit tricky: in the dir list it just changes the entrys value on a one
+ button press. but on a keyboard selection via gtk_widget_activate() it
+ does a new population (likewise on a double click) as this seems more
+ obvious.
+
+1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * gdk/gdkcolor.c (gdk_colormap_get_system): Initialize
+ private->ref_count.
+
+Wed Oct 22 09:47:43 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtkwindow.c (gtk_window_key_release_event): Fixed a stupid
+ bug that caused the key_release_event to be propagated twice.
+
+Sun Oct 12 11:01:43 1997 Tim Janik <timj@psynet.net>
+
+ * acconfig.h:
+ * configure.in:
+ * gdk/gdkimage.c: Added configure check for IPC_RMID_DEFERRED_RELEASE,
+ because shmat() fails after a shmctl(..., IPC_RMID,...) for OSF1 V3.2,
+ SunOS 4.1.1, 5.5, 5.5.1, 5.6, IRIX 5.2 and 6.2.
+
+Mon Oct 6 11:59:07 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gdk/gdk.c (gdk_event_translate): In line 1693, fixed typo that
+ would cause motion notify events not to be delivered.
+
+Sun Oct 5 18:15:06 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gtk/gtkrc.c (gtk_rc_parse_bg_pixmap): Changed strdup() for
+ g_strdup().
+
+Wed Sep 24 17:16:34 1997 Peter Mattis <pmattis@bjork.inktomi.com>
+
+ * configure.in: Fixed a stupid error in the test for libXext that
+ would cause it to fail if X_EXTRA_LIBS was not empty.
+
+ * gtk/gtkmain.h (gtk-timj-970919.patch):
+ * gtk/gtkmain.c (gtk-timj-970919.patch): new function
+ `gtk_idle_remove_by_data' to remove all idle callbacks that take a
+ specific piece of data as argument. (gtk_get_current_event):
+ remove idles through gtk_idle_remove_by_data.
+
+ * gtk/gtkwidget.c (gtk-timj-970919.patch):
+ (gtk_widget_destroy): remove pending idles for
+ widgets that have GTK_REDRAW_PENDING or GTK_RESIZE_PENDING and
+ GTK_ANCHORED set (only anchored widgets can have a resize queue
+ handler pending). widgets that have GTK_RESIZE_NEEDED will be removed
+ from their anchored toplevels `resize_widgets' list.
+
+ (gtk_widget_queue_draw): let the widget remember the queue handler
+ tag (through `redraw_handler_key') for later call to `gtk_idle_remove'.
+
+ (gtk_widget_queue_resize): let the widget remember the queue handler
+ tag (through `resize_handler_key') for later call to `gtk_idle_remove'.
+ corrected referencing the toplevel widget for which the handler is
+ pending. if a widget is added to the `resize_widgets' list of a
+ toplevel widget, GTK_RESIZE_NEEDED is set and it's referenced.
+
+ (gtk_real_widget_queue_resize): on the deletion of the `resize_widgets'
+ list, unset GTK_RESIZE_NEEDED and unreference the removed widgets.
+
+ * gtk/gtkwindow.c (gtk-timj-970919.patch):
+ (gtk_real_window_move_resize): move `resize_containers = NULL'
+ initialization out of if-statement.
+ while stepping through the `resize_widgets' list, unreference the
+ widgets and clear GTK_RESIZE_NEEDED. if a widget realy needs are
+ resize, they are flagged through GTK_RESIZE_NEEDED now (instead of
+ GTK_RESIZE_PENDING, as this is indicative for a pending handler).
+ added checks to provide segfaulting if a widgets parent pointer
+ is NULL (e.g. on toplevel widgets that have GTK_RESIZE_NEEDED set).
+
+Tue Sep 23 13:23:27 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gdk/gdkimage.c: Applied Tim Janik's patch to mark shm segments
+ as IPC_RMID so that they are automatically removed always.
+
+ * gdk/gdkfont.c: Removed casts from lvalues.
+
+ * gtk/gtkmain.c: Removed GTK_RETLOC_*() (which do a cast) from lvalues.
+
+ * gtk/gtkaccelerator.c (gtk_accelerator_table_remove): Added
+ "const" to the accelerator_key param to be consistent with the
+ declaration in gtkaccelerator.h. The const is not useful in this
+ case, anyway.
+
+Tue Sep 16 13:11:06 1997 Peter Mattis <pmattis@bjork.inktomi.com>
+
+ * gtkpreview.c: Andrew Logan Kieschnick's change to eliminate
+ round-off error when gamma is set to 1.0.
+
+ * gtkrange.c:
+ * gtkviewport.c: Jay Painter's changes to modify the way in which
+ viewports resize.
+
+ * gdkinput.c:
+ * gdkinputgxi.h:
+ * gdkinputxfree.h:
+ * gtk/Makefile.am:
+ * gtk.h:
+ * gtkeventbox.c:
+ * gtkeventbox.h: Owen Taylor's event box widget and fixes for X
+ input support (that I had broken).
+
+ * gdk.h:
+ * gdkwindow.c:
+ * gtksignal.h:
+ * gtksignal.c: Elliot Lee's changes to support Objective C. (id is
+ apparently a reserved word in Objective C).
+
+Sun Sep 14 22:33:15 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c (gtk_widget_queue_resize): If the toplevel container
+ is invisible we simply call "gtk_container_need_resize" on
+ it. This fixes a bug with option menus not redrawing correctly.
+
+ * gtkmenuitem.c (gtk_menu_item_enter): (gtk_menu_item_leave):
+ These functions now simply pass the event on to their parent. This
+ is necessary for menus to work properly due to the change in how
+ grabs are dealts with.
+
+ * gtkwindow.c (gtk_real_window_move_resize): Fixed a bug that
+ caused the GTK_RESIZE_PENDING flag to not be unset in some cases.
+
+Fri Sep 5 20:49:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
+
+ Bug fixes:
+
+ * Makefile.am: Added PATCHES to EXTRA_DIST.
+ * gtk/gtkpixmap.c (gtk_pixmap_new): Move the "pixmap != NULL" test
+ after the allocation of the pixmap.
+
+ To shut up the compiler:
+
+ * gtk/gtkfilesel.c (get_pwdb): Initialize home_dir.
+ * gtk/gtkmain.c (gtk_init): Replace comments around calls to
+ g_set_*_handler with "if (0)".
+ * gtk/gtkrc.c (gtk_rc_get_token): Initialize hex_number and
+ float_number.
+ * gtk/gtkwindow.c (gtk_window_key_press_event): Initialize
+ direction.
+
+ Changes to the type system in gtk/:
+
+ * Makefile.am: Added gtktypebuiltins.h to gtkinclude_HEADERS.
+ Added gtk.defs, runelisp, gentypeinfo.el and gtktypebuiltins.c to
+ EXTRA_DIST. Added rules to generate gtktypebuiltins.* from
+ gtk.defs.
+
+ * runelisp, gentypeinfo.el, gtk.defs: New files.
+
+ * gtkaccelerator.c, gtkaccelerator.h (gtk_accelerator_table_ref):
+ Return the table so that this function can be used as the `copy'
+ function for GTK_TYPE_BOXED values.
+ * gtkstyle.c, gtkstyle.h (gtk_style_ref): Likewise.
+
+ * gtkenums.h: Removed GtkArgType enum.
+
+ * gtkmain.c (gtk_init): Call gtk_type_init to initialize the type
+ system.
+
+ * gtkobject.c (gtk_object_init_type): New function to take over
+ for gtk_object_get_type. (gtk_object_get_type): Just return the
+ constant GTK_TYPE_OBJECT. (gtk_object_collect_args): Do the right
+ thing for the new GTK_TYPE_* types.
+ * gtksignal.c (gtk_params_get): Likewise.
+
+ * gtktypeutils.c: (gtk_type_init_builtin_types): New
+ function. (gtk_type_init): Call it. Also made non-static.
+ (gtk_type_unique): The allocation scheme for numerical ids has
+ changed: The low 8 bits hold the appropriate GtkFundamentalType of
+ a type, the rest is a globally unique sequence number.
+ (gtk_type_hash): Use the sequence number of a key to hash it.
+ (gtk_type_register_builtin): New function.
+
+ * gtktypeutils.h: (GtkFundamentalType): New enumeration of the
+ fundamental types. (GTK_TYPE_MAKE, GTK_FUNDAMENTAL_TYPE,
+ GTK_TYPE_SEQNO): New macros to work with the new id scheme.
+ (GtkArg): Added fields for new types and renamed old ones. GtkArg
+ should now be a mostly opaque structure, except name and type.
+ (GTK_VALUE_*): New macros to access the values of a GtkArg.
+ (GTK_RETLOC_*): New macros to access the location of a return
+ value that is contained in a GtkArg. * gtktypebuiltins.h: New
+ file to access the typeids of the builtin types.
+
+ * gtkwidget.h (GTK_TYPE_WIDGET): New macro to access the type id
+ of the widget class.
+
+ Thru out: Changed GTK_ARG_* to the appropriate GTK_TYPE_*.
+ Changed access to GtkArg structure to the appropriate GTK_VALUE_*
+ or GTK_RETLOC_* macro. Changed GtkArgType to GtkType. Changed
+ some guints to GtkType.
+
+ General changes in gtk/ to support interpreters:
+
+ * gtkradiobutton.c (gtk_radio_button_new_from_widget,
+ gtk_radio_button_new_with_label_from_widget): New functions.
+
+ * gtksignal.c (gtk_signal_connect_no_marshal): New function.
+ (struct _GtkHandler): Added no_marshal and destroy_func fields.
+ (gtk_signal_handler_new): Initialize them.
+ (gtk_signal_connect_by_type): Added no_marshal and destroy_func
+ arguments. Changed all callers.
+ (gtk_signal_destroy): Invoke destroy_func if there is one and the
+ global destroy func does not apply. (gtk_handlers_run): If the
+ handler has no_marshal set, call its function directly without
+ going thru the signal's marshaller.
+
+Wed Sep 3 09:56:22 1997 RHS Linux User <pmattis@bjork.inktomi.com>
+
+ * gtkrange.c: Changed the way the range control focus was drawn so
+ that the range control is drawn correctly when it does not have
+ the focus.
+
+Tue Sep 2 17:41:17 1997 RHS Linux User <pmattis@bjork.inktomi.com>
+
+ * gtkwidget.c: 'gtk_real_widget_queue_resize' should only remove
+ the "resize_widgets" if another resize is not pending.
+
+Mon Sep 1 18:28:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmain.c: Changed the way GDK_DELETE events are handled. Only,
+ if 'gtk_widget_event' returns TRUE is the widget destroyed. By
+ default, 'gtk_widget_event' will return FALSE causing the window
+ to not be destroyed. This prevents segfaults in the GIMP and other
+ programs that do not correctly handle GDK_DELETE events.
+
+ * gtkmain.c: Added modal dialog support by allowing events
+ destined for a child of the grab widget to go to the child instead
+ of the grab widget. (Added 'gtk_widget_is_ancestor' to determine
+ the relationship between the grab widget and the event widget).
+
+ * *.[ch]: Incorprated a whole mess of patches. (Started keeping
+ the ChangeLog up to date again).
+
+Thu Jun 5 17:22:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c:
+ * gtkmenufactory.h: Added 'gtk_menu_factory_remove_*'
+ calls. Removing entries/paths causes the associated widgets to be
+ destroyed.
+
+ * gtkwidget.c:
+ * gtkwidget.h: Calling 'gtk_widget_set_style' is used as an
+ indication that the programmer specifically wants that style to be
+ used. RC-style substitution is disabled for the widget after such
+ a call.
+
+ * gtkpixmap.c:
+ * gtkpixmap.h:
+ * gtkimage.c:
+ * gtkimage.h: Changed to use clip mask and a single pixmap (or
+ image) to deal with transparent areas.
+
+ * gdkpixmap.c: Modified xpm loading routines to optionally return
+ a clip mask.
+
+ * gdkgc.c:
+ * gdkdraw.c:
+ * gdktypes.h: Modifications to allow clip masks to be used with
+ gc's. Clip masks are bitmaps that specify drawable regions.
+
+Thu May 1 03:11:51 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkscrolledwindow.c: Scrolled windows need to have the
+ GTK_NO_WINDOW flag set. Not having it set caused an obscure
+ redrawing bug.
+
+Wed Apr 30 12:38:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkhruler.c:
+ * gtkvruler.c: Fixed a small bug that caused the indicator to be
+ positioned slightly off.
+
+Sun Apr 27 14:28:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c:
+ * gtkmenushell.h:
+ * gtkmenu.c:
+ * gtkmenu.h: Changes so that if a menu is popped up there is a
+ timeout period during which a menu item will not be activated and
+ if the mouse button is released in that period the menu will stay
+ popped up.
+
+ * gtkcurve.c:
+ * gtkcurve.h: Included curve widget courtesy of David
+ Mosberger-Tang (davidm@azstarnet.com).
+
+ * gtkentry.c:
+ * gtkentry.h: Changed "insert" and "delete" signals to
+ "insert_text" and "delete_text" respectively. (The symbol "delete"
+ cannot be used since it is a C++ reserved word).
+
+Sat Apr 19 01:43:49 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c: A path which ends in "<nothing>" will cause an
+ invisible (hidden) menu entry to be created. This is useful for
+ setting an accelerator key for which a corresponding menu entry is
+ not desired.
+
+ * gtktooltips.c: Fixed some problems with destruction of the
+ active tip widget not properly updating the tooltips data
+ structures.
+
+Fri Apr 18 15:09:45 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcontainer.c:
+ * gtklist.c:
+ * gtkwidget.c:
+ * gtkwidget.h: Patch from Owen Taylor (owt1@cornell.edu) which
+ fixes problems with destruction of objects and with destruction of
+ objects which hold the focus.
+
+Thu Apr 17 11:29:15 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c: Incorrect logic in
+ 'gtk_menu_shell_button_release' for deciding when a menu should
+ stay popped up when the mouse button is released.
+
+ * *.c: Miscellaneous fixes from folks on the net.
+
+Tue Apr 15 02:43:17 1997 Peter Mattis <pmattis@localhost>
+
+ * *.c:
+ * gtkwidget.h: Added GTK_BASIC widget flag which when set
+ specifies a widget as "basic". A "basic" widget is one which
+ doesn't take input events. For example, labels, pixmaps, boxes,
+ tables, alignments, etc.
+
+Sat Apr 12 15:23:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcolorsel.c: Add "#include <math.h>" to define M_PI.
+
+ * gtksignal.c: Fixed a bug in 'gtk_signal_emit' which showed up
+ because of the new cast checking macros. The 'object' was being
+ accessed after it had been destroyed.
+
+ * gtkoptionmenu.c: Fixed bug with using 'GTK_BIN' instead of
+ 'GTK_BUTTON' which showed up because of the new cast checking
+ macros.
+
+ * *.h: 'GTK_CHECK_CAST', 'GTK_CHECK_CLASS_CAST' and
+ 'GTK_CHECK_TYPE' used by standard widget macros everywhere.
+
+Wed Apr 9 00:54:17 1997 Peter Mattis <pmattis@localhost>
+
+ * docs/gtk.texi: Started further work on documentation. Major
+ changes and additions are being made.
+
+ * gtkarrow.c:
+ * gtkarrow.h: Removed function 'gtk_arrow_get'.
+
+ * gtkcontainer.c: 'gtk_container_check_resize' no performs
+ additional checking to account for the case where the containers
+ allocation is no longer sufficient because its parent (or its
+ parents parent, etc.) needs to resize its children.
+
+Tue Apr 8 21:15:50 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkstyle.c: Fixed a bug in 'gtk_style_init' in which the font
+ was not ref'd (via 'gdk_font_ref'), but was free'd (via in
+ 'gdk_font_free') in 'gtk_style_destroy'. (David
+ Mosberger-Tang). Also cleaned up 'gtk_style_destroy' while I was
+ at it.
+
+ * gtkmain.c: Fixed a bug in 'gtk_propogate_event' which caused
+ entry widgets (and probably other widgets) not to be destroyed in
+ some instances.
+
+Mon Apr 7 01:20:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkentry.c:
+ * gtkentry.h: Changed the "insert_text", "delete_text" and
+ "changed_text" signals to "insert", "delete", and "changed"
+ respectively. They really should have been named this way
+ originally except the previous signal mechanism prevented
+ duplicate signal names. ("changed" is also used by adjustments).
+
+ * gtkradiomenuitem.c:
+ * gtkradiomenuitem.h: New widget.
+
+ * gtkcheckmenuitem.c:
+ * gtkcheckmenuitem.h: New widget.
+
+ * gtksignal.c: Modified 'gtk_signal_lookup' to require an object
+ type to be passed as a parameter. In addition, signals are now
+ only needed to be uniquely defined in their branch of the class
+ hierarchy. This allows the same signal name to be used in two
+ different branches of the class hierarchy. For instance, the
+ "changed" signal is used both by adjustments and entries...in
+ different ways!
+
+ * gtktypeutils.c: Added 'gtk_type_parent' which returns the parent
+ type for a given type.
+
+Sun Apr 6 22:08:35 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c: If a widget is set insensitive it loses the focus
+ if it had it.
+
+ * gtkcontainer.c: Insensitive widgets no longer participate in tab
+ traversal.
+
+ * gtkscrolledwindow.c: The "viewport" child is now destroyed and a
+ container class "foreach" function was written (which fixes the
+ sensitivity bug).
+
+Sat Apr 5 14:25:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkhscrollbar.c:
+ * gtkvscrollbar.c: Fixed trough size allocation bug.
+
+ * gtkhscale.c:
+ * gtkvscale.c: Fixed trough size allocation and position bug that
+ showed up when scales were placed in notebooks.
+
+Thu Mar 27 17:45:54 1997 David Mosberger-Tang <davidm@azstarnet.com>
+
+ * gtk/gtkmain.c (gtk_handle_idle): Fix appending pending_idles to
+ idle_functions so it works even when idle_functions is empty.
+
+Sat Mar 15 14:15:59 1997 Peter Mattis <pmattis@localhost>
+
+ * *.[ch]: Moved '*_class_init' and '*_init' function declarations
+ for widgets into the source file as those functions no longer had
+ to be public.
+
+ * gtkcheckbutton.c: Fixed redrawing of check button.
+
+ * gtkframe.c: Fixed redrawing of frame when the shadow type is
+ changed.
+
+Sat Mar 8 15:19:23 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkimage.c: Fixed a stupid bug with 'gdk_image_new' which
+ potentially added a NULL image to "image_list" and caused problems
+ when 'gdk_image_exit' was called.
+
+Wed Mar 5 00:40:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkpreview.c: Massively changed the colormap handling used by
+ the preview widget. Gray previews are now dithered. A single
+ visual and colormap is shared by the color and gray previews. A
+ GTK_PREVIEW_INFO property is installed on the root window in
+ certain cases to allow multiple GTK programs to share the system
+ colormap.
+
+Sun Mar 2 05:43:06 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcheckbutton.c: 'gtk_checkbutton_size_allocate' was allocating
+ too much space to its children and not leaving the check button
+ room for the focus border.
+
+ * gtknotebook.c: 'gtk_notebook_size_request' wasn't requesting
+ enough space when the notebook tabs are visible.
+
+Sat Mar 1 01:59:35 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkpreview.c: Fixed a problem with 'gtk_preview_put' when the
+ image byte order is GDK_MSB_FIRST.
+
+ * gtksignal.c:
+ * gtksignal.h: Added 'gtk_signal_connect_after' and
+ 'gtk_signal_connect_object_after' functions. These connect signal
+ handlers which will run after the class function associated with
+ the signal.
+
+ * gtkstyle.c: Fixed a stupid bug in 'gtk_style_new_from_key' that
+ was causing twice as many styles to be created as necesary.
+
+ * gtkwidget.c: 'gtk_real_widget_size_allocate' erases the widgets
+ old allocation if it has the GTK_NO_WINDOW flag set.
+
+ * gtkwidget.c: 'gtk_real_widget_unmap' now erases the widget if it
+ has the GTK_NO_WINDOW flag set.
+
+ * gtklabel.c: Removed 'gtk_label_unmap' as similar functionality
+ was added to gtk_real_widget_unmap.
+
+ * gtkbin.c: Modified 'gtk_bin_map' and 'gtk_bin_unmap' so that it
+ erases and draws the widget if it has the GTK_NO_WINDOW flag set.
+
+ * gtkframe.c: Modified 'gtk_frame_size_allocate' so that it erases
+ the old allocation.
+
+Fri Feb 28 03:27:05 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: 'gtk_window_set_title' now changes the window title
+ if the window is already realized.
+
+ * gtkentry.c: 'gtk_entry_set_text' was emitting both a
+ "delete_text" and a "changed_text" signal. Modified so that it
+ only emits a "changed_text" signal.
+
+ * gtkpreview.c: Modified to work correctly on systems with MSB
+ byte order. The colormap for TRUE and DIRECT color displays is now
+ created if the default visual is not equal to the visual we are
+ using.
+
+ * gtkstyle.c: 'gtk_style_attach' and 'gtk_style_find' weren't
+ working properly in the presence of multiple colormaps are
+ different depth visuals.
+
+ * gtkcontainer.c: Massively improved focus traversal using tab and
+ arrow keys. It now uses the layout of the widgets to determine
+ where to move the focus to.
+
+Mon Feb 24 03:24:02 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c: Set the accelerator table field for menus when
+ they are created.
+
+ * gtkmenu.c:
+ * gtkmenu.h: Added a default accelerator table field to menus so
+ that runtime modification of accelerator keys in menus can work
+ better.
+
+ * gtkrange.c: 'gtk_range_default_{h,v}motion' had faulty logic for
+ deciding what to do when the slider was at the edge of the
+ trough. They previously didn't update the adjustment value event
+ if the value wasn't what it should be when the slider was at the
+ edge of the trough.
+
+ * gtkviewport.c: 'gtk_viewport_size_allocate' and
+ 'gtk_viewport_adjustment_value_changed' both had the potential for
+ performing a divide by 0. Checks are now in place to prevent this.
+
+ * gtkmenu.c: 'gtk_menu_map' now makes sure the menu lies on screen
+ if the position function is NULL.
+
+ * gtkentry.c: Modified selection handling. 'gtk_delete_selection'
+ actually removes the X selection now. 'gtk_entry_destroy' removes
+ the selection as well and relies on the change in "gdk.c" to make
+ sure the selection event will not be sent to a non-existant
+ window.
+
+ * gdk.c: Selection events are only passed on if the selection
+ owner is not NULL.
+
+ * gtkstyle.c: 'gtk_style_detach' and 'gtk_style_destroy' were not
+ destroying the black and white gc's.
+
+Sun Feb 23 19:17:56 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: 'gtk_window_size_request' was setting the window
+ hints. This was also being done in 'gtk_window_map', so the
+ instance being done in 'gtk_window_size_request' was removed.
+
+Fri Feb 21 01:04:01 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c: 'gtk_widget_draw' has to use the widgets allocated
+ position for the drawing rectangle when the widget has the
+ GTK_NO_WINDOW flag set.
+
+ * gtkwidget.c: In 'gtk_widget_init' the visual and colormap were
+ being directly compared against 'default_visual' and
+ 'default_colormap' instead of calling
+ 'gtk_widget_get_default_{visual,colormap}'.
+
+ * gdkrectangle.c: Amazing! There was a bug in the
+ 'gtk_rectangle_intersect' logic. Its been there for near eternity
+ and I never noticed.
+
+ * gtkpreview.c:
+ * gtkpreview.h: Created preview widget which allows drawing to an
+ rgb or grayscale buffer which is automatically displayed on the
+ screen. Performs dithering as necessary.
+
+Thu Feb 20 20:33:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkwindow.c: Modified the logic in 'gdk_window_new' which
+ determined when to add a window to the WM_COLORMAP_WINDOWS
+ property.
+
+Wed Feb 19 19:55:29 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkruler.c: 'gtk_ruler_make_pixmap' was always destroying the
+ old backing store and creating a new one even when it would create
+ a new one of exactly the same size as the old one.
+
+Tue Feb 18 18:32:10 1997 Peter Mattis <pmattis@localhost>
+
+ * gmem.c: 'g_mem_chunk_alloc' was incorrectly modifying the mem
+ areas free mem field when reallocating a previously freed
+ atom. This caused a fairly severe memory leak.
+
+ * gtkmenushell.c: 'gtk_menu_shell_button_release' had a bug in the
+ logic for deciding whether to initiate an X pointer grab or not
+ when the mouse button was released. It now only initiates a grab
+ if the mouse is released within an active menu item.
+
+Fri Feb 14 00:57:40 1997 Peter Mattis <pmattis@localhost>
+
+ * gtknotebook.c: Changed the look of notebook tabs slightly.
+
+ * gtkentry.c:
+ * gtkentry.h: Deleting an entry widget which is holding the X
+ selection presents some difficulties. The X selection must be
+ released, but the widget can't be destroyed until the
+ SELECTION_CLEAR event is received that the X server will send in
+ response to clearing the X selection. There are probably still
+ bugs in the current method of entry widget deletion when the X
+ selection is held.
+
+ * gtkmain.c: 'gtk_propagate_event' was not properly destroying the
+ toplevel window when receiving a key press event.
+
+ * gtkwidget.c: Setting a widget insensitive did not cause it to
+ redraw. It now does.
+
+Thu Feb 13 16:59:07 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkviewport.c: 'gtk_viewport_size_allocate' was allocating its
+ child widget an adjusted allocation. Since the actual scrolling
+ has handled by a subwindow this caused the child to be double
+ scrolled. Modified to always set the child allocations origin to
+ (0, 0).
+
+Wed Feb 12 01:06:48 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkentry.c: Text is now centered vertically. Previously it was
+ pushed up against the top. This problem was only evident when the
+ widget was allocated more vertical space than it requested.
+
+ * gtkfilesel.c: 'gtk_file_selection_key_press' was previously only
+ a stub for tab completion. The actual tab completion call had been
+ left out. (Oops!)
+
+Tue Feb 11 01:43:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtksignal.c: 'gtk_signal_disconnect_by_data' was going into a
+ loop and crashing. Bad logic. Fixed.
+
+ * gtkmain.c: An idle function which returns FALSE will be removed
+ from the list of idle functions. This makes the functioning of
+ idle functions and timeouts more similar.
+
+ * gtkentry.c: 'gtk_entry_get_text' now returns an empty string
+ when the actual text is NULL. This allows "stupid" programs to use
+ the value returned by 'gtk_entry_get_text' blindly (without
+ checking to see if its NULL).
+
+ * gtkradiobutton.c: Modified 'gtk_radio_button_clicked' so that
+ 'gtk_toggle_button_toggled' is called _after_ the widget state is
+ changed.
+
+ * gtksignal.c:
+ * gtksignal.h: Added 'gtk_signal_name' which returns the character
+ string name for a given signal number.
+
+ * gtkwidget.c: 'gtk_widget_set_parent' checks to see if the widget
+ is now "anchored" through the parent chain to a widget which is
+ GTK_ANCHORED. If it is, then it changes the widgets style using
+ 'gtk_rc_get_style' and recursively performs the same operation on
+ the widgets children. This is necessary is 'gtk_rc_get_style' only
+ works properly on "anchored" widgets.
+
+ * gtkwindow.c: Modified GTK_WIN_POS logic so that it is only used
+ immediately after the window has been shown.
+
+ * gtkmenu.c: 'gtk_menu_key_press'. Can now change menu item
+ accelerator keys on the fly. Why? Why not. Cool/useless feature of
+ the day.
+
+ * gtkmenuitem.c: Accelerator key drawing. Somehow that never got
+ finished. (Oops!)
+
+ * gtkdrawingarea.c: 'gtk_drawing_area_size_allocate' was not
+ actually installed during 'gtk_drawing_area_class_init'. (Oops!)
+
+ * gtkframe.c: 'gtk_frame_size_request' fixed size requisition
+ problem caused by unsigned arithmetic.
+
+ * gtkwindow.c: Modified window widget so that it only uses the
+ widget uposition auxiliary information immediately after it has
+ been shown. This prevents the annoying bug which can cause a
+ uposition'ed window to jump back to its original position after
+ the user moves it.
+
+ * gtkwidget.c: Need to ref and unref style in
+ 'gtk_widget_{push,pop}_style' to make sure that a style on the
+ style stack is not destroyed.
+
+ * gtktogglebutton.c: 'gtk_toggle_button_set_state' now calls
+ gtk_button_clicked to actually change the state of the
+ button. In this way, radio buttons can now perform the appropriate
+ actions when the toggle button state is set.
+
+Mon Feb 10 00:27:39 1997 Peter Mattis <pmattis@localhost>
+
+ * gtklist.c: 'gtk_list_select_item' and 'gtk_list_unselect_item'
+ were casting a GList* variable to a a GtkWidget* variable. Bad bad
+ bad. (Tim Janik).
+
+ * gtksignal.c: Modified 'gtk_signal_connect' and
+ 'gtk_signal_connect_object' to warn when a signal type cannot be
+ found.
+
+Sun Feb 9 00:15:30 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkoptionmenu.c:
+ * gtkoptionmenu.h: Changed option menus back to being derived from
+ buttons. This fixes up some screwiness with their user
+ interaction.
+
+ * gtkwindow.c: Modified key press handler to support focus
+ traversal.
+
+ * gtkcontainer.c:
+ * gtkcontainer.h: Added default focus traversal back in.
+
+Sat Feb 8 10:44:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkviewport.h:
+ * gtkviewport.c: Massively sped up viewport scrolling. Used to be
+ reallocating child's size (offset) each time a scrollbar
+ moved. Now a subwindow is moved. All the children are moved
+ automatically by moving the subwindow. Much much much faster.
+
+Tue Feb 4 00:20:44 1997 Peter Mattis <pmattis@localhost>
+
+ * gtree.c: Changed 'g_tree_node_search' to use a loop instead of
+ recursion.
+
+Mon Feb 3 11:30:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkbutton.c: Removed 'parent_destroy' global and replaced it
+ with 'parent_class' global to reflect style used in other
+ widgets.
+
+ * gtknotebook.c: Tab labels were being allocated less than their
+ requested size.
+
+ * gtkrange.c:
+ * gtkrange.h: Moved the "digits" field of scales into the range
+ type. The adjustment value for scales is truncated to the number
+ of visible digits instead of being left untouched.
+
+ * gtree.c: Fixed a bug in the AVL tree implementation. Single
+ rotations were always being performed during insertion. It is
+ sometimes necessary to perform a double rotation.
+
+ * gtklabel.c: Modified 'gtk_label_expose' to only draw the label
+ when the allocated space is greater than or equal to the requested
+ space.
+
+ * gtklabel.c: Added call to 'gtk_widget_unmap' to
+ 'gtk_label_destroy' in order for the label to redraw correctly
+ (erase itself) when destroyed.
+
+ * gtklabel.c: Added 'gtk_label_unmap' call which erases the labels
+ allocation when it gets unmapped.
+
+ * *.h: Removed a few remaining instances of using "class" as a
+ parameter name. (Causes problems for C++).
+
+Fri Jan 31 12:26:50 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcontainer.c: 'gtk_container_enable_resize' needs to call
+ 'gtk_container_check_resize' instead of
+ 'gtk_container_need_resize'.
+
+ * gtkwidget.c: 'gtk_real_widget_show' now maps the widget if its
+ parent is mapped.
+
+ * gtkscrolledwindow.c: Fixed size allocation when the scrollbar
+ policy's are GTK_POLICY_AUTOMATIC. Doing it correctly is harder
+ than I originally thought.
+
+ * gtklist.c: Added 'gtk_list_child_position' to determine the
+ integer position in a list of a child. Filled in the
+ 'gtk_list_item_select' and 'gtk_list_item_unselect' stubs.
+
+Thu Jan 30 16:08:06 1997 Peter Mattis <pmattis@localhost>
+
+ * gmem.c: Changed the implementation of G_ALLOC_AND_FREE mem
+ chunks. They used to allocate SIZEOF_VOID_P extra bytes per atom
+ in order to keep track of which mem area they were allocated
+ from. Now the mem area is determined by searching through an AVL
+ tree of the mem areas for a mem chunk and comparing memory
+ locations. A little slower, but makes G_ALLOC_AND_FREE mem chunks
+ much more attractive.
+
+ * gtree.c: Added an AVL tree implementation to glib.
+
+ * gtksignal.c:
+ * gstring.c: va_arg (arg_list, {char, short}) is
+ invalid. Arguments passed in a variable argument list are
+ promoted. ({char, short}->int). Seemed to work ok before under
+ Linux. Crashed under FreeBSD.
+
+Tue Jan 28 02:27:51 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkwindow.c: Fixed a major slowdown apparent in the file
+ selection dialog which was caused by calling
+ 'gtk_window_add_colormap_windows' way way way too often.
+
+ * *.c: Many widgets called 'gtk_container_need_resize' when
+ something internal changed which would cause the widget to grow or
+ shrink. The assumption was made that the widget would change size
+ and an expose event would be generated. This happens "most" of the
+ time. But its possible for certain widgets to change size without
+ generating expose events, or for its internal geometry to change
+ without a change of size which would mean no expose event was
+ generated. So a wrapper function called
+ 'gtk_container_check_resize' was created and
+ 'gtk_container_need_resize' was modified so that it returns FALSE
+ if a resize was actually generated and TRUE if nothing
+ changed. This allows 'gtk_container_check_resize' to initiate a
+ 'gtk_widget_size_allocate' and 'gtk_widget_draw' to emulate the
+ expose event.
+
+Sat Jan 25 14:17:44 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmain.c: Fixed a bug with propogating key press events. The
+ events were sent 2 times to the toplevel windows which caused the
+ focus widget to be activated twice when the space bar was pressed.
+
+ * */configure.in:
+ * */Makefile.am: Added support for libtool and removed the old
+ shared library configuration craziness.
+
+Fri Jan 24 12:59:22 1997 Peter Mattis <pmattis@localhost>
+
+ * gtktext.c:
+ * gtktext.h: Josh's fixes and additions to the text widget.
+
+ * gtkfill.c:
+ * gtkfill.h: Filler widget useful for filling space in a
+ table. Can specify a minimum size. Used by the canvas widget.
+
+ * gtknotebook.c:
+ * gtknotebook.h: Made outline of notebook widget.
+
+ * gtkcanvas.c:
+ * gtkcanvas.h: Started canvas widget. A composite of 2 rulers (w/
+ an origin), 2 scrolllbars. Guides, grids, snap to.
+
+Sun Jan 19 18:26:45 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkdialog.c:
+ * gtkdialog.h: Created dialog widget which creates a standard
+ looking dialog with buttons along the button and a separator.
+
+ * gtkxid.c: Generalized the window table code for looking up a gdk
+ window based on an XID to work for any XID and a piece of
+ data. Can now look up gdk fonts based on their XID.
+
+ * gtkruler.c:
+ * gtkruler.h:
+ * gtkhruler.c:
+ * gtkhruler.h:
+ * gtkvruler.c:
+ * gtkvruler.h: Started conversion of the ruler widget.
+
+ * gtktext.c:
+ * gtktext.h: Started conversion of the text widget. Scrolling
+ doesn't work.
+
+ * gtkmain.c: Fixed a fairly major bug. The event widget needs to
+ be in a call for the entire duration of handling an event. Not
+ just for when the event widget itself is handling the event.
+
+ * gtkfilesel.c: Fixed up some bugs with resizing.
+
+Fri Jan 10 14:18:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c:
+ * gtkwidget.h:
+ * gtkentry.c:
+ * gtkentry.h: Support for selections.
+
+ * gdkselection.c:
+ * gdk.c:
+ * gdktypes.h:
+ * gdk.h: Gdk support for X selections. Currently only text
+ selections are supported.
+
+ * gtksignal.c: Fixed a major bug which occurred when destroying an
+ object. Memory was being written to after it was freed.
+
+ * gtkfilesel.c:
+ * gtkfilesel.h: Hooked up more functionality to the file selection
+ dialog.
+
+Wed Jan 8 18:13:53 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkfilesel.c:
+ * gtkfilesel.h: Mostly converted old file selection dialog
+ widget. The widget is derived from the GtkWindow class and is
+ quite a bit simpler in the widget code.
+
+ * gtkwidget.c: Fixed 'gtk_widget_grab_focus' and
+ 'gtk_widget_grab_default' to check that the toplevel widget is a
+ type of window (which includes classes derived from windows).
+
+Tue Jan 7 01:12:32 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: Was calling 'gtk_window_resize' twice in a
+ row...why?
+
+ * gtksignal.c:
+ * gtksignal.h:
+ * *.c: Changed 'gtk_signal_new' so that the class function that is
+ called when the signal is emitted can be called either before,
+ after or both before and after the calling of any signal
+ handlers.
+
+ * gtkobject.c:
+ * gtkobject.h: Added 'object_data' mechanism for storing data
+ associated with a character string key in objects. Removed
+ 'user_data' field of objects and changed
+ 'gtk_object_{get,set}_user_data' to use the object data
+ mechanism. Removed 'handlers' field of objects.
+
+ * gtkwidget.c:
+ * gtkwidget.h:
+ * gtkwindow.c: Modified aux info mechanism to use object data
+ mechanism.
+
+ * gtksignal.c: Modified signal mechanism to use object data
+ mechanism instead of 'handlers' field.
+
+
+Mon Jan 6 15:10:16 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c: Fixed up button press handling so as to conform
+ more closely to that used by Motif.
+
+Wed Jan 1 21:27:17 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenu.c:
+ * gtkmenu.h:
+ * gtkmenubar.c:
+ * gtkmenubar.h:
+ * gtkmenushell.c:
+ * gtkmenushell.h: Reorganization of menu-ing code so that code
+ duplication is reduced. The menu shell now contains most of the
+ code for menu-ing interaction while menus and menubars simply layout
+ their child menu items in the appropriate place.
+
+Sun Dec 29 17:48:18 1996 Peter Mattis <pmattis@localhost>
+
+ * gtkmenu.c:
+ * gtkmenubar.c:
+ * gtkmenuitem.h:
+ * gtkmenuitem.c: Modifications so that menu item accelerators and
+ the submenu indicator are drawn correctly and the correct amount
+ of space is allocated.
+
+Sat Dec 28 00:32:13 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkmenufactory.h:
+ * gtkmenufactory.c: Started menu factories as an easy method to
+ create and manipulate menus.
+
+Fri Dec 27 13:17:34 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkmenu.c:
+ * gtkmenu.h:
+ * gtkmenubar.c:
+ * gtkmenubar.h:
+ * gtkmenuitem.c:
+ * gtkmenuitem.h:
+ * gtkmenushell.c:
+ * gtkmenushell.h: Implemented basic menu functionality. Menubars
+ and popup menus work. Submenus work. (Much left to be done).
+
+Wed Dec 18 15:27:05 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtktypeutils.h:
+ * gtktypeutils.c: Added 'gtk_type_from_name' which returns a type
+ identifier given a type name. Implemented using a second hash
+ table keyed by type names.
+
+ * gtkbutton.c:
+ * gtktogglebutton.c: Fixed very small messed-up drawing bug when a
+ button loses its focus.
+
+ * gtkwidget.h:
+ * gtkwidget.c:
+ * gtkbutton.c:
+ * gtkwindow.c: Added default button handling. Default buttons now
+ draw correctly and pressing return or enter causes the default
+ button (if one exists) to be activated.
+
+Tue Dec 17 19:32:21 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkhscale.c:
+ * gtkvscale.c: Overrode 'draw_slider' method of ranges in order to
+ draw the slider of scales with a line in them so as to be closer
+ to the Motif look-and-feel.
+
+ * gtkwindow.c: Modified 'gtk_window_focus_in_event' so that focus
+ in events are only handled when the window is visible. Fixes a bug
+ where spurious focus in events get sent when a window is being
+ hidden.
+
+ * gtkwidget.h: Added 'activate_signal' field to the GtkWidgetClass
+ structure. Added 'gtk_widget_activate' call to emit the activate
+ signal for a widget if it is non-zero.
+
+Tue Dec 10 15:59:45 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkwidget.c: 'gtk_widget_set_name' oops in strdup'ing the old
+ "widget->name" instead of the new one we are setting.
+
+ * gtkrc.c: 'gtk_rc_widget_path' changed to use
+ 'gtk_widget_get_name' instead of accessing the "widget->name"
+ field directly.
+
+ * gtkwidget.c: Added 'gtk_widget_get_name' function which returns
+ the widgets name if it exists and the widgets type name if it does
+ not.
+
+ * gtkcheckbutton.c: Added 'gtk_check_button_draw'
+ function. Modified 'gtk_check_button_expose' to pass an expose
+ event to child instead of callings its draw function.
+
+ * gtkentry.c: 'gtk_entry_draw_text' why was "+1" being added to
+ the font->ascent to calculate the font position? This was wrong
+ and caused some characters in fonts to be clipped. (Notably "g").
+
+ * gtkentry.c: 'gtk_entry_realize' specify GTK_BUTTON1_MOTION_MASK
+ and GTK_POINTER_MOTION_HINT_MASK for _both_ windows.
+
+ * gtkmain.c: 'gtk_propagate_event' needs to set the GTK_IN_CALL
+ flag for the object before calling 'gtk_widget_event' and needs to
+ destroy the object if necessary after 'gtk_widget_event' returns.
+
+ * gtkradiobutton.c: 'gtk_radio_button_clicked' needs to call
+ 'gtk_toggle_button_toggled' when the currently active button is
+ toggled.
+
+ * gtkwidget.c: 'gtk_real_widget_hide' needs to call
+ 'gtk_widget_unmap' if the widget is currently mapped.
+
+ * gtkwindow.c: Prevent automatic resizing after the user has
+ specified a new window size. Add 'handling_resize' flag to
+ windows.
+
+ * gtkscrolledwindow.c: Implement the GTK_POLICY_AUTOMATIC
+ scrollbar policy. Need to connect to the adjustments 'changed'
+ signal and notice when the scrollbars aren't in use.
+
+ * gtkcontainer.c: 'gtk_container_init' must set 'auto_resize' and
+ 'need_resize' fields to TRUE and FALSE respectively.
+
+ * gtkwidget.c: 'gtk_widget_set_parent' must all set a widgets state
+ to its parents state.
+
+Sun Dec 1 01:31:01 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * Started ChangeLog

+ to fix some viewport bugs
+
+Mon Nov 17 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtkwidget.c: gtk-ajaborsk-971016-2
+ A little patch again to prevent user to use gtk_widget_set_events()
+ when a widget is already realized.
+ In this case, the gtk_widget_set_events() doesn't work.
+
+Mon Nov 17 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtkwindow.c: gtk-ajaborsk-971016-1
+ This small patch correct position for GTK_WIN_POS_CENTER and
+ GTK_WIN_POS_MOUSE GtkWindow positions.
+
+Sat Nov 15 1997 Jay Painter <jpaint@serv.net>
+ * gdk/gdkgc.c: added function gdk_gc_set_clip_rectangle
+ * gdk/gdk.h: header for above

+ * gdk/gdkpixmap.c: Patrice Fortier's patch for transparent pixmaps.
+ * gdk/gdk.h:
+ gdk/gdkdraw.c: Patrice Fortier's patch to add pixel draw function.
+
+Sun Nov 9 1997 Jay Painter <jpaint@serv.net>
+ * Fixed problems with makefiles relating to the bug
+ which required glib to be installed.
+ * Fixed makefiles to incluce the xpm's in gtk+/gtk needed
+ for testgtk.
+ * Updated gtk+ and gtk+/glib to libtool-1.0f
+
+Fri Nov 7 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtktext.c: return char_widths[ch & 0xff]; in line 2152
+
+Thr Nov 5 1997 Jay Painter <jpaint@serv.net>
+ * gtk/testgtk.c: added drag and drop test, removed the test hack
+ from the button test
+
+Tue Nov 4 08:28:57 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gtk/gtkmain.c (gtk_handle_idle): Patch from David Mosberger to
+ avoid crashes when handling idle function (this manifested itself
+ in the Umax and Microtek backends in SANE.
+
+Sun Nov 2 07:34:56 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtkfilesel.c: Small fixes about a segmentation viaolation
+ cause by a double click in the directoy list (introduced by my
+ previous changes).
+
+ * gtk/gtklist.c: Small fixes to gtk_list_add() and gtk_list_remove().
+
+ * gtk/testgtk.c (list_add): Applied Stefan Wille's patch to make this
+ function do something ;).
+
+Fri Oct 31 Jay Painter <jpaint@serv.net>
+ *gdk/gdk.c: reformatted DND code for GTK coding standards
+ *gdk/gdkwindow.c: changed memory allocation for DND to q_mem stuff
+
+Thu Oct 30 Jay Painter <jpaint@serv.net>
+ * gdk/gdkwindow.c:

+
+ * gdk/gdkwindow:
+ * gdk/gdk.h:
+ * gtk/gtkwidget.h:
+ * gtk/gtkwidget.c: reformatted the DND code to conform to GTK
+ coding standards
+
+ * gtk/testgtk: massive fixes, SW's shaped window example
+
+Thu Oct 30 07:33:27 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtklistitem.c (gtk_real_list_item_toggle): applied Johannes
+ Keukelaar's <johannes@nada.kth.se> patch for keyboard support in
+ GtkList widgets.
+
+ * gtk/gtkfilesel.c: adapted dir and file list selection
+ behaviour to deal with keyboard selections. this is a little
+ bit tricky: in the dir list it just changes the entrys value on a one
+ button press. but on a keyboard selection via gtk_widget_activate() it
+ does a new population (likewise on a double click) as this seems more
+ obvious.
+
+1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * gdk/gdkcolor.c (gdk_colormap_get_system): Initialize
+ private->ref_count.
+
+Wed Oct 22 09:47:43 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtkwindow.c (gtk_window_key_release_event): Fixed a stupid
+ bug that caused the key_release_event to be propagated twice.
+
+Sun Oct 12 11:01:43 1997 Tim Janik <timj@psynet.net>
+
+ * acconfig.h:
+ * configure.in:
+ * gdk/gdkimage.c: Added configure check for IPC_RMID_DEFERRED_RELEASE,
+ because shmat() fails after a shmctl(..., IPC_RMID,...) for OSF1 V3.2,
+ SunOS 4.1.1, 5.5, 5.5.1, 5.6, IRIX 5.2 and 6.2.
+
+Mon Oct 6 11:59:07 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gdk/gdk.c (gdk_event_translate): In line 1693, fixed typo that
+ would cause motion notify events not to be delivered.
+
+Sun Oct 5 18:15:06 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gtk/gtkrc.c (gtk_rc_parse_bg_pixmap): Changed strdup() for
+ g_strdup().
+
+Wed Sep 24 17:16:34 1997 Peter Mattis <pmattis@bjork.inktomi.com>
+
+ * configure.in: Fixed a stupid error in the test for libXext that
+ would cause it to fail if X_EXTRA_LIBS was not empty.
+
+ * gtk/gtkmain.h (gtk-timj-970919.patch):
+ * gtk/gtkmain.c (gtk-timj-970919.patch): new function
+ `gtk_idle_remove_by_data' to remove all idle callbacks that take a
+ specific piece of data as argument. (gtk_get_current_event):
+ remove idles through gtk_idle_remove_by_data.
+
+ * gtk/gtkwidget.c (gtk-timj-970919.patch):
+ (gtk_widget_destroy): remove pending idles for
+ widgets that have GTK_REDRAW_PENDING or GTK_RESIZE_PENDING and
+ GTK_ANCHORED set (only anchored widgets can have a resize queue
+ handler pending). widgets that have GTK_RESIZE_NEEDED will be removed
+ from their anchored toplevels `resize_widgets' list.
+
+ (gtk_widget_queue_draw): let the widget remember the queue handler
+ tag (through `redraw_handler_key') for later call to `gtk_idle_remove'.
+
+ (gtk_widget_queue_resize): let the widget remember the queue handler
+ tag (through `resize_handler_key') for later call to `gtk_idle_remove'.
+ corrected referencing the toplevel widget for which the handler is
+ pending. if a widget is added to the `resize_widgets' list of a
+ toplevel widget, GTK_RESIZE_NEEDED is set and it's referenced.
+
+ (gtk_real_widget_queue_resize): on the deletion of the `resize_widgets'
+ list, unset GTK_RESIZE_NEEDED and unreference the removed widgets.
+
+ * gtk/gtkwindow.c (gtk-timj-970919.patch):
+ (gtk_real_window_move_resize): move `resize_containers = NULL'
+ initialization out of if-statement.
+ while stepping through the `resize_widgets' list, unreference the
+ widgets and clear GTK_RESIZE_NEEDED. if a widget realy needs are
+ resize, they are flagged through GTK_RESIZE_NEEDED now (instead of
+ GTK_RESIZE_PENDING, as this is indicative for a pending handler).
+ added checks to provide segfaulting if a widgets parent pointer
+ is NULL (e.g. on toplevel widgets that have GTK_RESIZE_NEEDED set).
+
+Tue Sep 23 13:23:27 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gdk/gdkimage.c: Applied Tim Janik's patch to mark shm segments
+ as IPC_RMID so that they are automatically removed always.
+
+ * gdk/gdkfont.c: Removed casts from lvalues.
+
+ * gtk/gtkmain.c: Removed GTK_RETLOC_*() (which do a cast) from lvalues.
+
+ * gtk/gtkaccelerator.c (gtk_accelerator_table_remove): Added
+ "const" to the accelerator_key param to be consistent with the
+ declaration in gtkaccelerator.h. The const is not useful in this
+ case, anyway.
+
+Tue Sep 16 13:11:06 1997 Peter Mattis <pmattis@bjork.inktomi.com>
+
+ * gtkpreview.c: Andrew Logan Kieschnick's change to eliminate
+ round-off error when gamma is set to 1.0.
+
+ * gtkrange.c:
+ * gtkviewport.c: Jay Painter's changes to modify the way in which
+ viewports resize.
+
+ * gdkinput.c:
+ * gdkinputgxi.h:
+ * gdkinputxfree.h:
+ * gtk/Makefile.am:
+ * gtk.h:
+ * gtkeventbox.c:

+ input support (that I had broken).
+
+ * gdk.h:
+ * gdkwindow.c:
+ * gtksignal.h:
+ * gtksignal.c: Elliot Lee's changes to support Objective C. (id is
+ apparently a reserved word in Objective C).
+
+Sun Sep 14 22:33:15 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c (gtk_widget_queue_resize): If the toplevel container
+ is invisible we simply call "gtk_container_need_resize" on
+ it. This fixes a bug with option menus not redrawing correctly.
+
+ * gtkmenuitem.c (gtk_menu_item_enter): (gtk_menu_item_leave):
+ These functions now simply pass the event on to their parent. This
+ is necessary for menus to work properly due to the change in how
+ grabs are dealts with.
+
+ * gtkwindow.c (gtk_real_window_move_resize): Fixed a bug that
+ caused the GTK_RESIZE_PENDING flag to not be unset in some cases.
+
+Fri Sep 5 20:49:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
+
+ Bug fixes:
+
+ * Makefile.am: Added PATCHES to EXTRA_DIST.
+ * gtk/gtkpixmap.c (gtk_pixmap_new): Move the "pixmap != NULL" test
+ after the allocation of the pixmap.
+
+ To shut up the compiler:
+
+ * gtk/gtkfilesel.c (get_pwdb): Initialize home_dir.
+ * gtk/gtkmain.c (gtk_init): Replace comments around calls to
+ g_set_*_handler with "if (0)".
+ * gtk/gtkrc.c (gtk_rc_get_token): Initialize hex_number and
+ float_number.
+ * gtk/gtkwindow.c (gtk_window_key_press_event): Initialize
+ direction.
+
+ Changes to the type system in gtk/:
+
+ * Makefile.am: Added gtktypebuiltins.h to gtkinclude_HEADERS.
+ Added gtk.defs, runelisp, gentypeinfo.el and gtktypebuiltins.c to
+ EXTRA_DIST. Added rules to generate gtktypebuiltins.* from
+ gtk.defs.
+
+ * runelisp, gentypeinfo.el, gtk.defs: New files.
+
+ * gtkaccelerator.c, gtkaccelerator.h (gtk_accelerator_table_ref):
+ Return the table so that this function can be used as the `copy'
+ function for GTK_TYPE_BOXED values.
+ * gtkstyle.c, gtkstyle.h (gtk_style_ref): Likewise.
+
+ * gtkenums.h: Removed GtkArgType enum.
+
+ * gtkmain.c (gtk_init): Call gtk_type_init to initialize the type
+ system.
+
+ * gtkobject.c (gtk_object_init_type): New function to take over
+ for gtk_object_get_type. (gtk_object_get_type): Just return the
+ constant GTK_TYPE_OBJECT. (gtk_object_collect_args): Do the right
+ thing for the new GTK_TYPE_* types.
+ * gtksignal.c (gtk_params_get): Likewise.
+
+ * gtktypeutils.c: (gtk_type_init_builtin_types): New
+ function. (gtk_type_init): Call it. Also made non-static.
+ (gtk_type_unique): The allocation scheme for numerical ids has
+ changed: The low 8 bits hold the appropriate GtkFundamentalType of
+ a type, the rest is a globally unique sequence number.
+ (gtk_type_hash): Use the sequence number of a key to hash it.
+ (gtk_type_register_builtin): New function.
+
+ * gtktypeutils.h: (GtkFundamentalType): New enumeration of the
+ fundamental types. (GTK_TYPE_MAKE, GTK_FUNDAMENTAL_TYPE,
+ GTK_TYPE_SEQNO): New macros to work with the new id scheme.
+ (GtkArg): Added fields for new types and renamed old ones. GtkArg
+ should now be a mostly opaque structure, except name and type.
+ (GTK_VALUE_*): New macros to access the values of a GtkArg.
+ (GTK_RETLOC_*): New macros to access the location of a return
+ value that is contained in a GtkArg. * gtktypebuiltins.h: New
+ file to access the typeids of the builtin types.
+
+ * gtkwidget.h (GTK_TYPE_WIDGET): New macro to access the type id
+ of the widget class.
+
+ Thru out: Changed GTK_ARG_* to the appropriate GTK_TYPE_*.
+ Changed access to GtkArg structure to the appropriate GTK_VALUE_*
+ or GTK_RETLOC_* macro. Changed GtkArgType to GtkType. Changed
+ some guints to GtkType.
+
+ General changes in gtk/ to support interpreters:
+
+ * gtkradiobutton.c (gtk_radio_button_new_from_widget,
+ gtk_radio_button_new_with_label_from_widget): New functions.
+
+ * gtksignal.c (gtk_signal_connect_no_marshal): New function.
+ (struct _GtkHandler): Added no_marshal and destroy_func fields.
+ (gtk_signal_handler_new): Initialize them.
+ (gtk_signal_connect_by_type): Added no_marshal and destroy_func
+ arguments. Changed all callers.
+ (gtk_signal_destroy): Invoke destroy_func if there is one and the
+ global destroy func does not apply. (gtk_handlers_run): If the
+ handler has no_marshal set, call its function directly without
+ going thru the signal's marshaller.
+
+Wed Sep 3 09:56:22 1997 RHS Linux User <pmattis@bjork.inktomi.com>
+
+ * gtkrange.c: Changed the way the range control focus was drawn so
+ that the range control is drawn correctly when it does not have
+ the focus.
+
+Tue Sep 2 17:41:17 1997 RHS Linux User <pmattis@bjork.inktomi.com>
+
+ * gtkwidget.c: 'gtk_real_widget_queue_resize' should only remove
+ the "resize_widgets" if another resize is not pending.
+
+Mon Sep 1 18:28:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmain.c: Changed the way GDK_DELETE events are handled. Only,
+ if 'gtk_widget_event' returns TRUE is the widget destroyed. By
+ default, 'gtk_widget_event' will return FALSE causing the window
+ to not be destroyed. This prevents segfaults in the GIMP and other
+ programs that do not correctly handle GDK_DELETE events.
+
+ * gtkmain.c: Added modal dialog support by allowing events
+ destined for a child of the grab widget to go to the child instead
+ of the grab widget. (Added 'gtk_widget_is_ancestor' to determine
+ the relationship between the grab widget and the event widget).
+
+ * *.[ch]: Incorprated a whole mess of patches. (Started keeping
+ the ChangeLog up to date again).
+
+Thu Jun 5 17:22:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c:
+ * gtkmenufactory.h: Added 'gtk_menu_factory_remove_*'
+ calls. Removing entries/paths causes the associated widgets to be
+ destroyed.
+
+ * gtkwidget.c:
+ * gtkwidget.h: Calling 'gtk_widget_set_style' is used as an
+ indication that the programmer specifically wants that style to be
+ used. RC-style substitution is disabled for the widget after such
+ a call.
+
+ * gtkpixmap.c:
+ * gtkpixmap.h:
+ * gtkimage.c:
+ * gtkimage.h: Changed to use clip mask and a single pixmap (or
+ image) to deal with transparent areas.
+
+ * gdkpixmap.c: Modified xpm loading routines to optionally return
+ a clip mask.
+
+ * gdkgc.c:
+ * gdkdraw.c:
+ * gdktypes.h: Modifications to allow clip masks to be used with
+ gc's. Clip masks are bitmaps that specify drawable regions.
+
+Thu May 1 03:11:51 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkscrolledwindow.c: Scrolled windows need to have the
+ GTK_NO_WINDOW flag set. Not having it set caused an obscure
+ redrawing bug.
+
+Wed Apr 30 12:38:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkhruler.c:
+ * gtkvruler.c: Fixed a small bug that caused the indicator to be
+ positioned slightly off.
+
+Sun Apr 27 14:28:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c:
+ * gtkmenushell.h:
+ * gtkmenu.c:
+ * gtkmenu.h: Changes so that if a menu is popped up there is a
+ timeout period during which a menu item will not be activated and
+ if the mouse button is released in that period the menu will stay
+ popped up.
+
+ * gtkcurve.c:
+ * gtkcurve.h: Included curve widget courtesy of David
+ Mosberger-Tang (davidm@azstarnet.com).
+
+ * gtkentry.c:
+ * gtkentry.h: Changed "insert" and "delete" signals to
+ "insert_text" and "delete_text" respectively. (The symbol "delete"
+ cannot be used since it is a C++ reserved word).
+
+Sat Apr 19 01:43:49 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c: A path which ends in "<nothing>" will cause an
+ invisible (hidden) menu entry to be created. This is useful for
+ setting an accelerator key for which a corresponding menu entry is
+ not desired.
+
+ * gtktooltips.c: Fixed some problems with destruction of the
+ active tip widget not properly updating the tooltips data
+ structures.
+
+Fri Apr 18 15:09:45 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcontainer.c:
+ * gtklist.c:
+ * gtkwidget.c:
+ * gtkwidget.h: Patch from Owen Taylor (owt1@cornell.edu) which
+ fixes problems with destruction of objects and with destruction of
+ objects which hold the focus.
+
+Thu Apr 17 11:29:15 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c: Incorrect logic in
+ 'gtk_menu_shell_button_release' for deciding when a menu should
+ stay popped up when the mouse button is released.
+
+ * *.c: Miscellaneous fixes from folks on the net.
+
+Tue Apr 15 02:43:17 1997 Peter Mattis <pmattis@localhost>
+
+ * *.c:
+ * gtkwidget.h: Added GTK_BASIC widget flag which when set
+ specifies a widget as "basic". A "basic" widget is one which
+ doesn't take input events. For example, labels, pixmaps, boxes,
+ tables, alignments, etc.
+
+Sat Apr 12 15:23:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcolorsel.c: Add "#include <math.h>" to define M_PI.
+
+ * gtksignal.c: Fixed a bug in 'gtk_signal_emit' which showed up
+ because of the new cast checking macros. The 'object' was being
+ accessed after it had been destroyed.
+
+ * gtkoptionmenu.c: Fixed bug with using 'GTK_BIN' instead of
+ 'GTK_BUTTON' which showed up because of the new cast checking
+ macros.
+
+ * *.h: 'GTK_CHECK_CAST', 'GTK_CHECK_CLASS_CAST' and
+ 'GTK_CHECK_TYPE' used by standard widget macros everywhere.
+
+Wed Apr 9 00:54:17 1997 Peter Mattis <pmattis@localhost>
+
+ * docs/gtk.texi: Started further work on documentation. Major
+ changes and additions are being made.
+
+ * gtkarrow.c:
+ * gtkarrow.h: Removed function 'gtk_arrow_get'.
+
+ * gtkcontainer.c: 'gtk_container_check_resize' no performs
+ additional checking to account for the case where the containers
+ allocation is no longer sufficient because its parent (or its
+ parents parent, etc.) needs to resize its children.
+
+Tue Apr 8 21:15:50 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkstyle.c: Fixed a bug in 'gtk_style_init' in which the font
+ was not ref'd (via 'gdk_font_ref'), but was free'd (via in
+ 'gdk_font_free') in 'gtk_style_destroy'. (David
+ Mosberger-Tang). Also cleaned up 'gtk_style_destroy' while I was
+ at it.
+
+ * gtkmain.c: Fixed a bug in 'gtk_propogate_event' which caused
+ entry widgets (and probably other widgets) not to be destroyed in
+ some instances.
+
+Mon Apr 7 01:20:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkentry.c:
+ * gtkentry.h: Changed the "insert_text", "delete_text" and
+ "changed_text" signals to "insert", "delete", and "changed"
+ respectively. They really should have been named this way
+ originally except the previous signal mechanism prevented
+ duplicate signal names. ("changed" is also used by adjustments).
+
+ * gtkradiomenuitem.c:
+ * gtkradiomenuitem.h: New widget.
+
+ * gtkcheckmenuitem.c:
+ * gtkcheckmenuitem.h: New widget.
+
+ * gtksignal.c: Modified 'gtk_signal_lookup' to require an object
+ type to be passed as a parameter. In addition, signals are now
+ only needed to be uniquely defined in their branch of the class
+ hierarchy. This allows the same signal name to be used in two
+ different branches of the class hierarchy. For instance, the
+ "changed" signal is used both by adjustments and entries...in
+ different ways!
+
+ * gtktypeutils.c: Added 'gtk_type_parent' which returns the parent
+ type for a given type.
+
+Sun Apr 6 22:08:35 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c: If a widget is set insensitive it loses the focus
+ if it had it.
+
+ * gtkcontainer.c: Insensitive widgets no longer participate in tab
+ traversal.
+
+ * gtkscrolledwindow.c: The "viewport" child is now destroyed and a
+ container class "foreach" function was written (which fixes the
+ sensitivity bug).
+
+Sat Apr 5 14:25:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkhscrollbar.c:
+ * gtkvscrollbar.c: Fixed trough size allocation bug.
+
+ * gtkhscale.c:
+ * gtkvscale.c: Fixed trough size allocation and position bug that
+ showed up when scales were placed in notebooks.
+
+Thu Mar 27 17:45:54 1997 David Mosberger-Tang <davidm@azstarnet.com>
+
+ * gtk/gtkmain.c (gtk_handle_idle): Fix appending pending_idles to
+ idle_functions so it works even when idle_functions is empty.
+
+Sat Mar 15 14:15:59 1997 Peter Mattis <pmattis@localhost>
+
+ * *.[ch]: Moved '*_class_init' and '*_init' function declarations
+ for widgets into the source file as those functions no longer had
+ to be public.
+
+ * gtkcheckbutton.c: Fixed redrawing of check button.
+
+ * gtkframe.c: Fixed redrawing of frame when the shadow type is
+ changed.
+
+Sat Mar 8 15:19:23 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkimage.c: Fixed a stupid bug with 'gdk_image_new' which
+ potentially added a NULL image to "image_list" and caused problems
+ when 'gdk_image_exit' was called.
+
+Wed Mar 5 00:40:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkpreview.c: Massively changed the colormap handling used by
+ the preview widget. Gray previews are now dithered. A single
+ visual and colormap is shared by the color and gray previews. A
+ GTK_PREVIEW_INFO property is installed on the root window in
+ certain cases to allow multiple GTK programs to share the system
+ colormap.
+
+Sun Mar 2 05:43:06 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcheckbutton.c: 'gtk_checkbutton_size_allocate' was allocating
+ too much space to its children and not leaving the check button
+ room for the focus border.
+
+ * gtknotebook.c: 'gtk_notebook_size_request' wasn't requesting
+ enough space when the notebook tabs are visible.
+
+Sat Mar 1 01:59:35 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkpreview.c: Fixed a problem with 'gtk_preview_put' when the
+ image byte order is GDK_MSB_FIRST.
+
+ * gtksignal.c:
+ * gtksignal.h: Added 'gtk_signal_connect_after' and
+ 'gtk_signal_connect_object_after' functions. These connect signal
+ handlers which will run after the class function associated with
+ the signal.
+
+ * gtkstyle.c: Fixed a stupid bug in 'gtk_style_new_from_key' that
+ was causing twice as many styles to be created as necesary.
+
+ * gtkwidget.c: 'gtk_real_widget_size_allocate' erases the widgets
+ old allocation if it has the GTK_NO_WINDOW flag set.
+
+ * gtkwidget.c: 'gtk_real_widget_unmap' now erases the widget if it
+ has the GTK_NO_WINDOW flag set.
+
+ * gtklabel.c: Removed 'gtk_label_unmap' as similar functionality
+ was added to gtk_real_widget_unmap.
+
+ * gtkbin.c: Modified 'gtk_bin_map' and 'gtk_bin_unmap' so that it
+ erases and draws the widget if it has the GTK_NO_WINDOW flag set.
+
+ * gtkframe.c: Modified 'gtk_frame_size_allocate' so that it erases
+ the old allocation.
+
+Fri Feb 28 03:27:05 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: 'gtk_window_set_title' now changes the window title
+ if the window is already realized.
+
+ * gtkentry.c: 'gtk_entry_set_text' was emitting both a
+ "delete_text" and a "changed_text" signal. Modified so that it
+ only emits a "changed_text" signal.
+
+ * gtkpreview.c: Modified to work correctly on systems with MSB
+ byte order. The colormap for TRUE and DIRECT color displays is now
+ created if the default visual is not equal to the visual we are
+ using.
+
+ * gtkstyle.c: 'gtk_style_attach' and 'gtk_style_find' weren't
+ working properly in the presence of multiple colormaps are
+ different depth visuals.
+
+ * gtkcontainer.c: Massively improved focus traversal using tab and
+ arrow keys. It now uses the layout of the widgets to determine
+ where to move the focus to.
+
+Mon Feb 24 03:24:02 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c: Set the accelerator table field for menus when
+ they are created.
+
+ * gtkmenu.c:
+ * gtkmenu.h: Added a default accelerator table field to menus so
+ that runtime modification of accelerator keys in menus can work
+ better.
+
+ * gtkrange.c: 'gtk_range_default_{h,v}motion' had faulty logic for
+ deciding what to do when the slider was at the edge of the
+ trough. They previously didn't update the adjustment value event
+ if the value wasn't what it should be when the slider was at the
+ edge of the trough.
+
+ * gtkviewport.c: 'gtk_viewport_size_allocate' and
+ 'gtk_viewport_adjustment_value_changed' both had the potential for
+ performing a divide by 0. Checks are now in place to prevent this.
+
+ * gtkmenu.c: 'gtk_menu_map' now makes sure the menu lies on screen
+ if the position function is NULL.
+
+ * gtkentry.c: Modified selection handling. 'gtk_delete_selection'
+ actually removes the X selection now. 'gtk_entry_destroy' removes
+ the selection as well and relies on the change in "gdk.c" to make
+ sure the selection event will not be sent to a non-existant
+ window.
+
+ * gdk.c: Selection events are only passed on if the selection
+ owner is not NULL.
+
+ * gtkstyle.c: 'gtk_style_detach' and 'gtk_style_destroy' were not
+ destroying the black and white gc's.
+
+Sun Feb 23 19:17:56 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: 'gtk_window_size_request' was setting the window
+ hints. This was also being done in 'gtk_window_map', so the
+ instance being done in 'gtk_window_size_request' was removed.
+
+Fri Feb 21 01:04:01 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c: 'gtk_widget_draw' has to use the widgets allocated
+ position for the drawing rectangle when the widget has the
+ GTK_NO_WINDOW flag set.
+
+ * gtkwidget.c: In 'gtk_widget_init' the visual and colormap were
+ being directly compared against 'default_visual' and
+ 'default_colormap' instead of calling
+ 'gtk_widget_get_default_{visual,colormap}'.
+
+ * gdkrectangle.c: Amazing! There was a bug in the
+ 'gtk_rectangle_intersect' logic. Its been there for near eternity
+ and I never noticed.
+
+ * gtkpreview.c:
+ * gtkpreview.h: Created preview widget which allows drawing to an
+ rgb or grayscale buffer which is automatically displayed on the
+ screen. Performs dithering as necessary.
+
+Thu Feb 20 20:33:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkwindow.c: Modified the logic in 'gdk_window_new' which
+ determined when to add a window to the WM_COLORMAP_WINDOWS
+ property.
+
+Wed Feb 19 19:55:29 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkruler.c: 'gtk_ruler_make_pixmap' was always destroying the
+ old backing store and creating a new one even when it would create
+ a new one of exactly the same size as the old one.
+
+Tue Feb 18 18:32:10 1997 Peter Mattis <pmattis@localhost>
+
+ * gmem.c: 'g_mem_chunk_alloc' was incorrectly modifying the mem
+ areas free mem field when reallocating a previously freed
+ atom. This caused a fairly severe memory leak.
+
+ * gtkmenushell.c: 'gtk_menu_shell_button_release' had a bug in the
+ logic for deciding whether to initiate an X pointer grab or not
+ when the mouse button was released. It now only initiates a grab
+ if the mouse is released within an active menu item.
+
+Fri Feb 14 00:57:40 1997 Peter Mattis <pmattis@localhost>
+
+ * gtknotebook.c: Changed the look of notebook tabs slightly.
+
+ * gtkentry.c:
+ * gtkentry.h: Deleting an entry widget which is holding the X
+ selection presents some difficulties. The X selection must be
+ released, but the widget can't be destroyed until the
+ SELECTION_CLEAR event is received that the X server will send in
+ response to clearing the X selection. There are probably still
+ bugs in the current method of entry widget deletion when the X
+ selection is held.
+
+ * gtkmain.c: 'gtk_propagate_event' was not properly destroying the
+ toplevel window when receiving a key press event.
+
+ * gtkwidget.c: Setting a widget insensitive did not cause it to
+ redraw. It now does.
+
+Thu Feb 13 16:59:07 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkviewport.c: 'gtk_viewport_size_allocate' was allocating its
+ child widget an adjusted allocation. Since the actual scrolling
+ has handled by a subwindow this caused the child to be double
+ scrolled. Modified to always set the child allocations origin to
+ (0, 0).
+
+Wed Feb 12 01:06:48 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkentry.c: Text is now centered vertically. Previously it was
+ pushed up against the top. This problem was only evident when the
+ widget was allocated more vertical space than it requested.
+
+ * gtkfilesel.c: 'gtk_file_selection_key_press' was previously only
+ a stub for tab completion. The actual tab completion call had been
+ left out. (Oops!)
+
+Tue Feb 11 01:43:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtksignal.c: 'gtk_signal_disconnect_by_data' was going into a
+ loop and crashing. Bad logic. Fixed.
+
+ * gtkmain.c: An idle function which returns FALSE will be removed
+ from the list of idle functions. This makes the functioning of
+ idle functions and timeouts more similar.
+
+ * gtkentry.c: 'gtk_entry_get_text' now returns an empty string
+ when the actual text is NULL. This allows "stupid" programs to use
+ the value returned by 'gtk_entry_get_text' blindly (without
+ checking to see if its NULL).
+
+ * gtkradiobutton.c: Modified 'gtk_radio_button_clicked' so that
+ 'gtk_toggle_button_toggled' is called _after_ the widget state is
+ changed.
+
+ * gtksignal.c:
+ * gtksignal.h: Added 'gtk_signal_name' which returns the character
+ string name for a given signal number.
+
+ * gtkwidget.c: 'gtk_widget_set_parent' checks to see if the widget
+ is now "anchored" through the parent chain to a widget which is
+ GTK_ANCHORED. If it is, then it changes the widgets style using
+ 'gtk_rc_get_style' and recursively performs the same operation on
+ the widgets children. This is necessary is 'gtk_rc_get_style' only
+ works properly on "anchored" widgets.
+
+ * gtkwindow.c: Modified GTK_WIN_POS logic so that it is only used
+ immediately after the window has been shown.
+
+ * gtkmenu.c: 'gtk_menu_key_press'. Can now change menu item
+ accelerator keys on the fly. Why? Why not. Cool/useless feature of
+ the day.
+
+ * gtkmenuitem.c: Accelerator key drawing. Somehow that never got
+ finished. (Oops!)
+
+ * gtkdrawingarea.c: 'gtk_drawing_area_size_allocate' was not
+ actually installed during 'gtk_drawing_area_class_init'. (Oops!)
+
+ * gtkframe.c: 'gtk_frame_size_request' fixed size requisition
+ problem caused by unsigned arithmetic.
+
+ * gtkwindow.c: Modified window widget so that it only uses the
+ widget uposition auxiliary information immediately after it has
+ been shown. This prevents the annoying bug which can cause a
+ uposition'ed window to jump back to its original position after
+ the user moves it.
+
+ * gtkwidget.c: Need to ref and unref style in
+ 'gtk_widget_{push,pop}_style' to make sure that a style on the
+ style stack is not destroyed.
+
+ * gtktogglebutton.c: 'gtk_toggle_button_set_state' now calls
+ gtk_button_clicked to actually change the state of the
+ button. In this way, radio buttons can now perform the appropriate
+ actions when the toggle button state is set.
+
+Mon Feb 10 00:27:39 1997 Peter Mattis <pmattis@localhost>
+
+ * gtklist.c: 'gtk_list_select_item' and 'gtk_list_unselect_item'
+ were casting a GList* variable to a a GtkWidget* variable. Bad bad
+ bad. (Tim Janik).
+
+ * gtksignal.c: Modified 'gtk_signal_connect' and
+ 'gtk_signal_connect_object' to warn when a signal type cannot be
+ found.
+
+Sun Feb 9 00:15:30 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkoptionmenu.c:
+ * gtkoptionmenu.h: Changed option menus back to being derived from
+ buttons. This fixes up some screwiness with their user
+ interaction.
+
+ * gtkwindow.c: Modified key press handler to support focus
+ traversal.
+
+ * gtkcontainer.c:
+ * gtkcontainer.h: Added default focus traversal back in.
+
+Sat Feb 8 10:44:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkviewport.h:
+ * gtkviewport.c: Massively sped up viewport scrolling. Used to be
+ reallocating child's size (offset) each time a scrollbar
+ moved. Now a subwindow is moved. All the children are moved
+ automatically by moving the subwindow. Much much much faster.
+
+Tue Feb 4 00:20:44 1997 Peter Mattis <pmattis@localhost>
+
+ * gtree.c: Changed 'g_tree_node_search' to use a loop instead of
+ recursion.
+
+Mon Feb 3 11:30:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkbutton.c: Removed 'parent_destroy' global and replaced it
+ with 'parent_class' global to reflect style used in other
+ widgets.
+
+ * gtknotebook.c: Tab labels were being allocated less than their
+ requested size.
+
+ * gtkrange.c:
+ * gtkrange.h: Moved the "digits" field of scales into the range
+ type. The adjustment value for scales is truncated to the number
+ of visible digits instead of being left untouched.
+
+ * gtree.c: Fixed a bug in the AVL tree implementation. Single
+ rotations were always being performed during insertion. It is
+ sometimes necessary to perform a double rotation.
+
+ * gtklabel.c: Modified 'gtk_label_expose' to only draw the label
+ when the allocated space is greater than or equal to the requested
+ space.
+
+ * gtklabel.c: Added call to 'gtk_widget_unmap' to
+ 'gtk_label_destroy' in order for the label to redraw correctly
+ (erase itself) when destroyed.
+
+ * gtklabel.c: Added 'gtk_label_unmap' call which erases the labels
+ allocation when it gets unmapped.
+
+ * *.h: Removed a few remaining instances of using "class" as a
+ parameter name. (Causes problems for C++).
+
+Fri Jan 31 12:26:50 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcontainer.c: 'gtk_container_enable_resize' needs to call
+ 'gtk_container_check_resize' instead of
+ 'gtk_container_need_resize'.
+
+ * gtkwidget.c: 'gtk_real_widget_show' now maps the widget if its
+ parent is mapped.
+
+ * gtkscrolledwindow.c: Fixed size allocation when the scrollbar
+ policy's are GTK_POLICY_AUTOMATIC. Doing it correctly is harder
+ than I originally thought.
+
+ * gtklist.c: Added 'gtk_list_child_position' to determine the
+ integer position in a list of a child. Filled in the
+ 'gtk_list_item_select' and 'gtk_list_item_unselect' stubs.
+
+Thu Jan 30 16:08:06 1997 Peter Mattis <pmattis@localhost>
+
+ * gmem.c: Changed the implementation of G_ALLOC_AND_FREE mem
+ chunks. They used to allocate SIZEOF_VOID_P extra bytes per atom
+ in order to keep track of which mem area they were allocated
+ from. Now the mem area is determined by searching through an AVL
+ tree of the mem areas for a mem chunk and comparing memory
+ locations. A little slower, but makes G_ALLOC_AND_FREE mem chunks
+ much more attractive.
+
+ * gtree.c: Added an AVL tree implementation to glib.
+
+ * gtksignal.c:
+ * gstring.c: va_arg (arg_list, {char, short}) is
+ invalid. Arguments passed in a variable argument list are
+ promoted. ({char, short}->int). Seemed to work ok before under
+ Linux. Crashed under FreeBSD.
+
+Tue Jan 28 02:27:51 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkwindow.c: Fixed a major slowdown apparent in the file
+ selection dialog which was caused by calling
+ 'gtk_window_add_colormap_windows' way way way too often.
+
+ * *.c: Many widgets called 'gtk_container_need_resize' when
+ something internal changed which would cause the widget to grow or
+ shrink. The assumption was made that the widget would change size
+ and an expose event would be generated. This happens "most" of the
+ time. But its possible for certain widgets to change size without
+ generating expose events, or for its internal geometry to change
+ without a change of size which would mean no expose event was
+ generated. So a wrapper function called
+ 'gtk_container_check_resize' was created and
+ 'gtk_container_need_resize' was modified so that it returns FALSE
+ if a resize was actually generated and TRUE if nothing
+ changed. This allows 'gtk_container_check_resize' to initiate a
+ 'gtk_widget_size_allocate' and 'gtk_widget_draw' to emulate the
+ expose event.
+
+Sat Jan 25 14:17:44 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmain.c: Fixed a bug with propogating key press events. The
+ events were sent 2 times to the toplevel windows which caused the
+ focus widget to be activated twice when the space bar was pressed.
+
+ * */configure.in:
+ * */Makefile.am: Added support for libtool and removed the old
+ shared library configuration craziness.
+
+Fri Jan 24 12:59:22 1997 Peter Mattis <pmattis@localhost>
+
+ * gtktext.c:
+ * gtktext.h: Josh's fixes and additions to the text widget.
+
+ * gtkfill.c:
+ * gtkfill.h: Filler widget useful for filling space in a
+ table. Can specify a minimum size. Used by the canvas widget.
+
+ * gtknotebook.c:
+ * gtknotebook.h: Made outline of notebook widget.
+
+ * gtkcanvas.c:
+ * gtkcanvas.h: Started canvas widget. A composite of 2 rulers (w/
+ an origin), 2 scrolllbars. Guides, grids, snap to.
+
+Sun Jan 19 18:26:45 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkdialog.c:
+ * gtkdialog.h: Created dialog widget which creates a standard
+ looking dialog with buttons along the button and a separator.
+
+ * gtkxid.c: Generalized the window table code for looking up a gdk
+ window based on an XID to work for any XID and a piece of
+ data. Can now look up gdk fonts based on their XID.
+
+ * gtkruler.c:
+ * gtkruler.h:
+ * gtkhruler.c:
+ * gtkhruler.h:
+ * gtkvruler.c:
+ * gtkvruler.h: Started conversion of the ruler widget.
+
+ * gtktext.c:
+ * gtktext.h: Started conversion of the text widget. Scrolling
+ doesn't work.
+
+ * gtkmain.c: Fixed a fairly major bug. The event widget needs to
+ be in a call for the entire duration of handling an event. Not
+ just for when the event widget itself is handling the event.
+
+ * gtkfilesel.c: Fixed up some bugs with resizing.
+
+Fri Jan 10 14:18:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c:
+ * gtkwidget.h:
+ * gtkentry.c:
+ * gtkentry.h: Support for selections.
+
+ * gdkselection.c:
+ * gdk.c:
+ * gdktypes.h:
+ * gdk.h: Gdk support for X selections. Currently only text
+ selections are supported.
+
+ * gtksignal.c: Fixed a major bug which occurred when destroying an
+ object. Memory was being written to after it was freed.
+
+ * gtkfilesel.c:
+ * gtkfilesel.h: Hooked up more functionality to the file selection
+ dialog.
+
+Wed Jan 8 18:13:53 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkfilesel.c:
+ * gtkfilesel.h: Mostly converted old file selection dialog
+ widget. The widget is derived from the GtkWindow class and is
+ quite a bit simpler in the widget code.
+
+ * gtkwidget.c: Fixed 'gtk_widget_grab_focus' and
+ 'gtk_widget_grab_default' to check that the toplevel widget is a
+ type of window (which includes classes derived from windows).
+
+Tue Jan 7 01:12:32 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: Was calling 'gtk_window_resize' twice in a
+ row...why?
+
+ * gtksignal.c:
+ * gtksignal.h:
+ * *.c: Changed 'gtk_signal_new' so that the class function that is
+ called when the signal is emitted can be called either before,
+ after or both before and after the calling of any signal
+ handlers.
+
+ * gtkobject.c:
+ * gtkobject.h: Added 'object_data' mechanism for storing data
+ associated with a character string key in objects. Removed
+ 'user_data' field of objects and changed
+ 'gtk_object_{get,set}_user_data' to use the object data
+ mechanism. Removed 'handlers' field of objects.
+
+ * gtkwidget.c:
+ * gtkwidget.h:
+ * gtkwindow.c: Modified aux info mechanism to use object data
+ mechanism.
+
+ * gtksignal.c: Modified signal mechanism to use object data
+ mechanism instead of 'handlers' field.
+
+
+Mon Jan 6 15:10:16 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c: Fixed up button press handling so as to conform
+ more closely to that used by Motif.
+
+Wed Jan 1 21:27:17 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenu.c:
+ * gtkmenu.h:
+ * gtkmenubar.c:
+ * gtkmenubar.h:
+ * gtkmenushell.c:
+ * gtkmenushell.h: Reorganization of menu-ing code so that code
+ duplication is reduced. The menu shell now contains most of the
+ code for menu-ing interaction while menus and menubars simply layout
+ their child menu items in the appropriate place.
+
+Sun Dec 29 17:48:18 1996 Peter Mattis <pmattis@localhost>
+
+ * gtkmenu.c:
+ * gtkmenubar.c:
+ * gtkmenuitem.h:
+ * gtkmenuitem.c: Modifications so that menu item accelerators and
+ the submenu indicator are drawn correctly and the correct amount
+ of space is allocated.
+
+Sat Dec 28 00:32:13 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkmenufactory.h:
+ * gtkmenufactory.c: Started menu factories as an easy method to
+ create and manipulate menus.
+
+Fri Dec 27 13:17:34 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkmenu.c:
+ * gtkmenu.h:
+ * gtkmenubar.c:
+ * gtkmenubar.h:
+ * gtkmenuitem.c:
+ * gtkmenuitem.h:
+ * gtkmenushell.c:
+ * gtkmenushell.h: Implemented basic menu functionality. Menubars
+ and popup menus work. Submenus work. (Much left to be done).
+
+Wed Dec 18 15:27:05 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtktypeutils.h:
+ * gtktypeutils.c: Added 'gtk_type_from_name' which returns a type
+ identifier given a type name. Implemented using a second hash
+ table keyed by type names.
+
+ * gtkbutton.c:
+ * gtktogglebutton.c: Fixed very small messed-up drawing bug when a
+ button loses its focus.
+
+ * gtkwidget.h:
+ * gtkwidget.c:
+ * gtkbutton.c:
+ * gtkwindow.c: Added default button handling. Default buttons now
+ draw correctly and pressing return or enter causes the default
+ button (if one exists) to be activated.
+
+Tue Dec 17 19:32:21 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkhscale.c:
+ * gtkvscale.c: Overrode 'draw_slider' method of ranges in order to
+ draw the slider of scales with a line in them so as to be closer
+ to the Motif look-and-feel.
+
+ * gtkwindow.c: Modified 'gtk_window_focus_in_event' so that focus
+ in events are only handled when the window is visible. Fixes a bug
+ where spurious focus in events get sent when a window is being
+ hidden.
+
+ * gtkwidget.h: Added 'activate_signal' field to the GtkWidgetClass
+ structure. Added 'gtk_widget_activate' call to emit the activate
+ signal for a widget if it is non-zero.
+
+Tue Dec 10 15:59:45 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkwidget.c: 'gtk_widget_set_name' oops in strdup'ing the old
+ "widget->name" instead of the new one we are setting.
+
+ * gtkrc.c: 'gtk_rc_widget_path' changed to use
+ 'gtk_widget_get_name' instead of accessing the "widget->name"
+ field directly.
+
+ * gtkwidget.c: Added 'gtk_widget_get_name' function which returns
+ the widgets name if it exists and the widgets type name if it does
+ not.
+
+ * gtkcheckbutton.c: Added 'gtk_check_button_draw'
+ function. Modified 'gtk_check_button_expose' to pass an expose
+ event to child instead of callings its draw function.
+
+ * gtkentry.c: 'gtk_entry_draw_text' why was "+1" being added to
+ the font->ascent to calculate the font position? This was wrong
+ and caused some characters in fonts to be clipped. (Notably "g").
+
+ * gtkentry.c: 'gtk_entry_realize' specify GTK_BUTTON1_MOTION_MASK
+ and GTK_POINTER_MOTION_HINT_MASK for _both_ windows.
+
+ * gtkmain.c: 'gtk_propagate_event' needs to set the GTK_IN_CALL
+ flag for the object before calling 'gtk_widget_event' and needs to
+ destroy the object if necessary after 'gtk_widget_event' returns.
+
+ * gtkradiobutton.c: 'gtk_radio_button_clicked' needs to call
+ 'gtk_toggle_button_toggled' when the currently active button is
+ toggled.
+
+ * gtkwidget.c: 'gtk_real_widget_hide' needs to call
+ 'gtk_widget_unmap' if the widget is currently mapped.
+
+ * gtkwindow.c: Prevent automatic resizing after the user has
+ specified a new window size. Add 'handling_resize' flag to
+ windows.
+
+ * gtkscrolledwindow.c: Implement the GTK_POLICY_AUTOMATIC
+ scrollbar policy. Need to connect to the adjustments 'changed'
+ signal and notice when the scrollbars aren't in use.
+
+ * gtkcontainer.c: 'gtk_container_init' must set 'auto_resize' and
+ 'need_resize' fields to TRUE and FALSE respectively.
+
+ * gtkwidget.c: 'gtk_widget_set_parent' must all set a widgets state
+ to its parents state.
+
+Sun Dec 1 01:31:01 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * Started ChangeLog

+ * gtkviewport.c: Raph's Mon, 10 Nov 1997 patch to gtk-list
+ to fix some viewport bugs
+
+Mon Nov 17 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtkwidget.c: gtk-ajaborsk-971016-2
+ A little patch again to prevent user to use gtk_widget_set_events()
+ when a widget is already realized.
+ In this case, the gtk_widget_set_events() doesn't work.
+
+Mon Nov 17 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtkwindow.c: gtk-ajaborsk-971016-1
+ This small patch correct position for GTK_WIN_POS_CENTER and
+ GTK_WIN_POS_MOUSE GtkWindow positions.
+
+Sat Nov 15 1997 Jay Painter <jpaint@serv.net>
+ * gdk/gdkgc.c: added function gdk_gc_set_clip_rectangle
+ * gdk/gdk.h: header for above
+
+Sat Nov 15 1997 Jay Painter <jpaint@serv.net>
+ * gdk/gdkgc.c: added function gdk_gc_set_clip_rectangle

+Wed Nov 12 1997 Jay Painter <jpaint@serv.net>
+ * gdk/gdkpixmap.c: Patrice Fortier's patch for transparent pixmaps.
+ * gdk/gdk.h:
+ gdk/gdkdraw.c: Patrice Fortier's patch to add pixel draw function.
+
+Sun Nov 9 1997 Jay Painter <jpaint@serv.net>
+ * Fixed problems with makefiles relating to the bug
+ which required glib to be installed.
+ * Fixed makefiles to incluce the xpm's in gtk+/gtk needed
+ for testgtk.
+ * Updated gtk+ and gtk+/glib to libtool-1.0f
+
+Fri Nov 7 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtktext.c: return char_widths[ch & 0xff]; in line 2152
+
+Thr Nov 5 1997 Jay Painter <jpaint@serv.net>
+ * gtk/testgtk.c: added drag and drop test, removed the test hack
+ from the button test
+
+Tue Nov 4 08:28:57 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gtk/gtkmain.c (gtk_handle_idle): Patch from David Mosberger to
+ avoid crashes when handling idle function (this manifested itself
+ in the Umax and Microtek backends in SANE.
+
+Sun Nov 2 07:34:56 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtkfilesel.c: Small fixes about a segmentation viaolation
+ cause by a double click in the directoy list (introduced by my
+ previous changes).
+
+ * gtk/gtklist.c: Small fixes to gtk_list_add() and gtk_list_remove().
+
+ * gtk/testgtk.c (list_add): Applied Stefan Wille's patch to make this
+ function do something ;).
+
+Fri Oct 31 Jay Painter <jpaint@serv.net>
+ *gdk/gdk.c: reformatted DND code for GTK coding standards
+ *gdk/gdkwindow.c: changed memory allocation for DND to q_mem stuff
+
+Thu Oct 30 Jay Painter <jpaint@serv.net>
+ * gdk/gdkwindow.c:
+ * gdk/gdk/gdk.h:
+ * gtk/gtkwidget.h:
+ * gtk/gtkwidget.c: Applied Stephan Willie's shaped window patch
+
+ * gdk/gdkwindow:
+ * gdk/gdk.h:
+ * gtk/gtkwidget.h:
+ * gtk/gtkwidget.c: reformatted the DND code to conform to GTK
+ coding standards
+
+ * gtk/testgtk: massive fixes, SW's shaped window example
+
+Thu Oct 30 07:33:27 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtklistitem.c (gtk_real_list_item_toggle): applied Johannes
+ Keukelaar's <johannes@nada.kth.se> patch for keyboard support in
+ GtkList widgets.
+
+ * gtk/gtkfilesel.c: adapted dir and file list selection
+ behaviour to deal with keyboard selections. this is a little
+ bit tricky: in the dir list it just changes the entrys value on a one
+ button press. but on a keyboard selection via gtk_widget_activate() it
+ does a new population (likewise on a double click) as this seems more
+ obvious.
+
+1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * gdk/gdkcolor.c (gdk_colormap_get_system): Initialize
+ private->ref_count.
+
+Wed Oct 22 09:47:43 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtkwindow.c (gtk_window_key_release_event): Fixed a stupid
+ bug that caused the key_release_event to be propagated twice.
+
+Sun Oct 12 11:01:43 1997 Tim Janik <timj@psynet.net>
+
+ * acconfig.h:
+ * configure.in:
+ * gdk/gdkimage.c: Added configure check for IPC_RMID_DEFERRED_RELEASE,
+ because shmat() fails after a shmctl(..., IPC_RMID,...) for OSF1 V3.2,
+ SunOS 4.1.1, 5.5, 5.5.1, 5.6, IRIX 5.2 and 6.2.
+
+Mon Oct 6 11:59:07 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gdk/gdk.c (gdk_event_translate): In line 1693, fixed typo that
+ would cause motion notify events not to be delivered.
+
+Sun Oct 5 18:15:06 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gtk/gtkrc.c (gtk_rc_parse_bg_pixmap): Changed strdup() for
+ g_strdup().
+
+Wed Sep 24 17:16:34 1997 Peter Mattis <pmattis@bjork.inktomi.com>
+
+ * configure.in: Fixed a stupid error in the test for libXext that
+ would cause it to fail if X_EXTRA_LIBS was not empty.
+
+ * gtk/gtkmain.h (gtk-timj-970919.patch):
+ * gtk/gtkmain.c (gtk-timj-970919.patch): new function
+ `gtk_idle_remove_by_data' to remove all idle callbacks that take a
+ specific piece of data as argument. (gtk_get_current_event):
+ remove idles through gtk_idle_remove_by_data.
+
+ * gtk/gtkwidget.c (gtk-timj-970919.patch):
+ (gtk_widget_destroy): remove pending idles for
+ widgets that have GTK_REDRAW_PENDING or GTK_RESIZE_PENDING and
+ GTK_ANCHORED set (only anchored widgets can have a resize queue
+ handler pending). widgets that have GTK_RESIZE_NEEDED will be removed
+ from their anchored toplevels `resize_widgets' list.
+
+ (gtk_widget_queue_draw): let the widget remember the queue handler
+ tag (through `redraw_handler_key') for later call to `gtk_idle_remove'.
+
+ (gtk_widget_queue_resize): let the widget remember the queue handler
+ tag (through `resize_handler_key') for later call to `gtk_idle_remove'.
+ corrected referencing the toplevel widget for which the handler is
+ pending. if a widget is added to the `resize_widgets' list of a
+ toplevel widget, GTK_RESIZE_NEEDED is set and it's referenced.
+
+ (gtk_real_widget_queue_resize): on the deletion of the `resize_widgets'
+ list, unset GTK_RESIZE_NEEDED and unreference the removed widgets.
+
+ * gtk/gtkwindow.c (gtk-timj-970919.patch):
+ (gtk_real_window_move_resize): move `resize_containers = NULL'
+ initialization out of if-statement.
+ while stepping through the `resize_widgets' list, unreference the
+ widgets and clear GTK_RESIZE_NEEDED. if a widget realy needs are
+ resize, they are flagged through GTK_RESIZE_NEEDED now (instead of
+ GTK_RESIZE_PENDING, as this is indicative for a pending handler).
+ added checks to provide segfaulting if a widgets parent pointer
+ is NULL (e.g. on toplevel widgets that have GTK_RESIZE_NEEDED set).
+
+Tue Sep 23 13:23:27 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gdk/gdkimage.c: Applied Tim Janik's patch to mark shm segments
+ as IPC_RMID so that they are automatically removed always.
+
+ * gdk/gdkfont.c: Removed casts from lvalues.
+
+ * gtk/gtkmain.c: Removed GTK_RETLOC_*() (which do a cast) from lvalues.
+
+ * gtk/gtkaccelerator.c (gtk_accelerator_table_remove): Added
+ "const" to the accelerator_key param to be consistent with the
+ declaration in gtkaccelerator.h. The const is not useful in this
+ case, anyway.
+
+Tue Sep 16 13:11:06 1997 Peter Mattis <pmattis@bjork.inktomi.com>
+
+ * gtkpreview.c: Andrew Logan Kieschnick's change to eliminate
+ round-off error when gamma is set to 1.0.
+
+ * gtkrange.c:
+ * gtkviewport.c: Jay Painter's changes to modify the way in which
+ viewports resize.
+
+ * gdkinput.c:
+ * gdkinputgxi.h:
+ * gdkinputxfree.h:
+ * gtk/Makefile.am:
+ * gtk.h:
+ * gtkeventbox.c:
+ * gtkeventbox.h: Owen Taylor's event box widget and fixes for X
+ input support (that I had broken).
+
+ * gdk.h:
+ * gdkwindow.c:
+ * gtksignal.h:
+ * gtksignal.c: Elliot Lee's changes to support Objective C. (id is
+ apparently a reserved word in Objective C).
+
+Sun Sep 14 22:33:15 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c (gtk_widget_queue_resize): If the toplevel container
+ is invisible we simply call "gtk_container_need_resize" on
+ it. This fixes a bug with option menus not redrawing correctly.
+
+ * gtkmenuitem.c (gtk_menu_item_enter): (gtk_menu_item_leave):
+ These functions now simply pass the event on to their parent. This
+ is necessary for menus to work properly due to the change in how
+ grabs are dealts with.
+
+ * gtkwindow.c (gtk_real_window_move_resize): Fixed a bug that
+ caused the GTK_RESIZE_PENDING flag to not be unset in some cases.
+
+Fri Sep 5 20:49:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
+
+ Bug fixes:
+
+ * Makefile.am: Added PATCHES to EXTRA_DIST.
+ * gtk/gtkpixmap.c (gtk_pixmap_new): Move the "pixmap != NULL" test
+ after the allocation of the pixmap.
+
+ To shut up the compiler:
+
+ * gtk/gtkfilesel.c (get_pwdb): Initialize home_dir.
+ * gtk/gtkmain.c (gtk_init): Replace comments around calls to
+ g_set_*_handler with "if (0)".
+ * gtk/gtkrc.c (gtk_rc_get_token): Initialize hex_number and
+ float_number.
+ * gtk/gtkwindow.c (gtk_window_key_press_event): Initialize
+ direction.
+
+ Changes to the type system in gtk/:
+
+ * Makefile.am: Added gtktypebuiltins.h to gtkinclude_HEADERS.
+ Added gtk.defs, runelisp, gentypeinfo.el and gtktypebuiltins.c to
+ EXTRA_DIST. Added rules to generate gtktypebuiltins.* from
+ gtk.defs.
+
+ * runelisp, gentypeinfo.el, gtk.defs: New files.
+
+ * gtkaccelerator.c, gtkaccelerator.h (gtk_accelerator_table_ref):
+ Return the table so that this function can be used as the `copy'
+ function for GTK_TYPE_BOXED values.
+ * gtkstyle.c, gtkstyle.h (gtk_style_ref): Likewise.
+
+ * gtkenums.h: Removed GtkArgType enum.
+
+ * gtkmain.c (gtk_init): Call gtk_type_init to initialize the type
+ system.
+
+ * gtkobject.c (gtk_object_init_type): New function to take over
+ for gtk_object_get_type. (gtk_object_get_type): Just return the
+ constant GTK_TYPE_OBJECT. (gtk_object_collect_args): Do the right
+ thing for the new GTK_TYPE_* types.
+ * gtksignal.c (gtk_params_get): Likewise.
+
+ * gtktypeutils.c: (gtk_type_init_builtin_types): New
+ function. (gtk_type_init): Call it. Also made non-static.
+ (gtk_type_unique): The allocation scheme for numerical ids has
+ changed: The low 8 bits hold the appropriate GtkFundamentalType of
+ a type, the rest is a globally unique sequence number.
+ (gtk_type_hash): Use the sequence number of a key to hash it.
+ (gtk_type_register_builtin): New function.
+
+ * gtktypeutils.h: (GtkFundamentalType): New enumeration of the
+ fundamental types. (GTK_TYPE_MAKE, GTK_FUNDAMENTAL_TYPE,
+ GTK_TYPE_SEQNO): New macros to work with the new id scheme.
+ (GtkArg): Added fields for new types and renamed old ones. GtkArg
+ should now be a mostly opaque structure, except name and type.
+ (GTK_VALUE_*): New macros to access the values of a GtkArg.
+ (GTK_RETLOC_*): New macros to access the location of a return
+ value that is contained in a GtkArg. * gtktypebuiltins.h: New
+ file to access the typeids of the builtin types.
+
+ * gtkwidget.h (GTK_TYPE_WIDGET): New macro to access the type id
+ of the widget class.
+
+ Thru out: Changed GTK_ARG_* to the appropriate GTK_TYPE_*.
+ Changed access to GtkArg structure to the appropriate GTK_VALUE_*
+ or GTK_RETLOC_* macro. Changed GtkArgType to GtkType. Changed
+ some guints to GtkType.
+
+ General changes in gtk/ to support interpreters:
+
+ * gtkradiobutton.c (gtk_radio_button_new_from_widget,
+ gtk_radio_button_new_with_label_from_widget): New functions.
+
+ * gtksignal.c (gtk_signal_connect_no_marshal): New function.
+ (struct _GtkHandler): Added no_marshal and destroy_func fields.
+ (gtk_signal_handler_new): Initialize them.
+ (gtk_signal_connect_by_type): Added no_marshal and destroy_func
+ arguments. Changed all callers.
+ (gtk_signal_destroy): Invoke destroy_func if there is one and the
+ global destroy func does not apply. (gtk_handlers_run): If the
+ handler has no_marshal set, call its function directly without
+ going thru the signal's marshaller.
+
+Wed Sep 3 09:56:22 1997 RHS Linux User <pmattis@bjork.inktomi.com>
+
+ * gtkrange.c: Changed the way the range control focus was drawn so
+ that the range control is drawn correctly when it does not have
+ the focus.
+
+Tue Sep 2 17:41:17 1997 RHS Linux User <pmattis@bjork.inktomi.com>
+
+ * gtkwidget.c: 'gtk_real_widget_queue_resize' should only remove
+ the "resize_widgets" if another resize is not pending.
+
+Mon Sep 1 18:28:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmain.c: Changed the way GDK_DELETE events are handled. Only,
+ if 'gtk_widget_event' returns TRUE is the widget destroyed. By
+ default, 'gtk_widget_event' will return FALSE causing the window
+ to not be destroyed. This prevents segfaults in the GIMP and other
+ programs that do not correctly handle GDK_DELETE events.
+
+ * gtkmain.c: Added modal dialog support by allowing events
+ destined for a child of the grab widget to go to the child instead
+ of the grab widget. (Added 'gtk_widget_is_ancestor' to determine
+ the relationship between the grab widget and the event widget).
+
+ * *.[ch]: Incorprated a whole mess of patches. (Started keeping
+ the ChangeLog up to date again).
+
+Thu Jun 5 17:22:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c:
+ * gtkmenufactory.h: Added 'gtk_menu_factory_remove_*'
+ calls. Removing entries/paths causes the associated widgets to be
+ destroyed.
+
+ * gtkwidget.c:
+ * gtkwidget.h: Calling 'gtk_widget_set_style' is used as an
+ indication that the programmer specifically wants that style to be
+ used. RC-style substitution is disabled for the widget after such
+ a call.
+
+ * gtkpixmap.c:
+ * gtkpixmap.h:
+ * gtkimage.c:
+ * gtkimage.h: Changed to use clip mask and a single pixmap (or
+ image) to deal with transparent areas.
+
+ * gdkpixmap.c: Modified xpm loading routines to optionally return
+ a clip mask.
+
+ * gdkgc.c:
+ * gdkdraw.c:
+ * gdktypes.h: Modifications to allow clip masks to be used with
+ gc's. Clip masks are bitmaps that specify drawable regions.
+
+Thu May 1 03:11:51 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkscrolledwindow.c: Scrolled windows need to have the
+ GTK_NO_WINDOW flag set. Not having it set caused an obscure
+ redrawing bug.
+
+Wed Apr 30 12:38:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkhruler.c:
+ * gtkvruler.c: Fixed a small bug that caused the indicator to be
+ positioned slightly off.
+
+Sun Apr 27 14:28:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c:
+ * gtkmenushell.h:
+ * gtkmenu.c:
+ * gtkmenu.h: Changes so that if a menu is popped up there is a
+ timeout period during which a menu item will not be activated and
+ if the mouse button is released in that period the menu will stay
+ popped up.
+
+ * gtkcurve.c:
+ * gtkcurve.h: Included curve widget courtesy of David
+ Mosberger-Tang (davidm@azstarnet.com).
+
+ * gtkentry.c:
+ * gtkentry.h: Changed "insert" and "delete" signals to
+ "insert_text" and "delete_text" respectively. (The symbol "delete"
+ cannot be used since it is a C++ reserved word).
+
+Sat Apr 19 01:43:49 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c: A path which ends in "<nothing>" will cause an
+ invisible (hidden) menu entry to be created. This is useful for
+ setting an accelerator key for which a corresponding menu entry is
+ not desired.
+
+ * gtktooltips.c: Fixed some problems with destruction of the
+ active tip widget not properly updating the tooltips data
+ structures.
+
+Fri Apr 18 15:09:45 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcontainer.c:
+ * gtklist.c:
+ * gtkwidget.c:
+ * gtkwidget.h: Patch from Owen Taylor (owt1@cornell.edu) which
+ fixes problems with destruction of objects and with destruction of
+ objects which hold the focus.
+
+Thu Apr 17 11:29:15 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c: Incorrect logic in
+ 'gtk_menu_shell_button_release' for deciding when a menu should
+ stay popped up when the mouse button is released.
+
+ * *.c: Miscellaneous fixes from folks on the net.
+
+Tue Apr 15 02:43:17 1997 Peter Mattis <pmattis@localhost>
+
+ * *.c:
+ * gtkwidget.h: Added GTK_BASIC widget flag which when set
+ specifies a widget as "basic". A "basic" widget is one which
+ doesn't take input events. For example, labels, pixmaps, boxes,
+ tables, alignments, etc.
+
+Sat Apr 12 15:23:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcolorsel.c: Add "#include <math.h>" to define M_PI.
+
+ * gtksignal.c: Fixed a bug in 'gtk_signal_emit' which showed up
+ because of the new cast checking macros. The 'object' was being
+ accessed after it had been destroyed.
+
+ * gtkoptionmenu.c: Fixed bug with using 'GTK_BIN' instead of
+ 'GTK_BUTTON' which showed up because of the new cast checking
+ macros.
+
+ * *.h: 'GTK_CHECK_CAST', 'GTK_CHECK_CLASS_CAST' and
+ 'GTK_CHECK_TYPE' used by standard widget macros everywhere.
+
+Wed Apr 9 00:54:17 1997 Peter Mattis <pmattis@localhost>
+
+ * docs/gtk.texi: Started further work on documentation. Major
+ changes and additions are being made.
+
+ * gtkarrow.c:
+ * gtkarrow.h: Removed function 'gtk_arrow_get'.
+
+ * gtkcontainer.c: 'gtk_container_check_resize' no performs
+ additional checking to account for the case where the containers
+ allocation is no longer sufficient because its parent (or its
+ parents parent, etc.) needs to resize its children.
+
+Tue Apr 8 21:15:50 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkstyle.c: Fixed a bug in 'gtk_style_init' in which the font
+ was not ref'd (via 'gdk_font_ref'), but was free'd (via in
+ 'gdk_font_free') in 'gtk_style_destroy'. (David
+ Mosberger-Tang). Also cleaned up 'gtk_style_destroy' while I was
+ at it.
+
+ * gtkmain.c: Fixed a bug in 'gtk_propogate_event' which caused
+ entry widgets (and probably other widgets) not to be destroyed in
+ some instances.
+
+Mon Apr 7 01:20:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkentry.c:
+ * gtkentry.h: Changed the "insert_text", "delete_text" and
+ "changed_text" signals to "insert", "delete", and "changed"
+ respectively. They really should have been named this way
+ originally except the previous signal mechanism prevented
+ duplicate signal names. ("changed" is also used by adjustments).
+
+ * gtkradiomenuitem.c:
+ * gtkradiomenuitem.h: New widget.
+
+ * gtkcheckmenuitem.c:
+ * gtkcheckmenuitem.h: New widget.
+
+ * gtksignal.c: Modified 'gtk_signal_lookup' to require an object
+ type to be passed as a parameter. In addition, signals are now
+ only needed to be uniquely defined in their branch of the class
+ hierarchy. This allows the same signal name to be used in two
+ different branches of the class hierarchy. For instance, the
+ "changed" signal is used both by adjustments and entries...in
+ different ways!
+
+ * gtktypeutils.c: Added 'gtk_type_parent' which returns the parent
+ type for a given type.
+
+Sun Apr 6 22:08:35 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c: If a widget is set insensitive it loses the focus
+ if it had it.
+
+ * gtkcontainer.c: Insensitive widgets no longer participate in tab
+ traversal.
+
+ * gtkscrolledwindow.c: The "viewport" child is now destroyed and a
+ container class "foreach" function was written (which fixes the
+ sensitivity bug).
+
+Sat Apr 5 14:25:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkhscrollbar.c:
+ * gtkvscrollbar.c: Fixed trough size allocation bug.
+
+ * gtkhscale.c:
+ * gtkvscale.c: Fixed trough size allocation and position bug that
+ showed up when scales were placed in notebooks.
+
+Thu Mar 27 17:45:54 1997 David Mosberger-Tang <davidm@azstarnet.com>
+
+ * gtk/gtkmain.c (gtk_handle_idle): Fix appending pending_idles to
+ idle_functions so it works even when idle_functions is empty.
+
+Sat Mar 15 14:15:59 1997 Peter Mattis <pmattis@localhost>
+
+ * *.[ch]: Moved '*_class_init' and '*_init' function declarations
+ for widgets into the source file as those functions no longer had
+ to be public.
+
+ * gtkcheckbutton.c: Fixed redrawing of check button.
+
+ * gtkframe.c: Fixed redrawing of frame when the shadow type is
+ changed.
+
+Sat Mar 8 15:19:23 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkimage.c: Fixed a stupid bug with 'gdk_image_new' which
+ potentially added a NULL image to "image_list" and caused problems
+ when 'gdk_image_exit' was called.
+
+Wed Mar 5 00:40:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkpreview.c: Massively changed the colormap handling used by
+ the preview widget. Gray previews are now dithered. A single
+ visual and colormap is shared by the color and gray previews. A
+ GTK_PREVIEW_INFO property is installed on the root window in
+ certain cases to allow multiple GTK programs to share the system
+ colormap.
+
+Sun Mar 2 05:43:06 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcheckbutton.c: 'gtk_checkbutton_size_allocate' was allocating
+ too much space to its children and not leaving the check button
+ room for the focus border.
+
+ * gtknotebook.c: 'gtk_notebook_size_request' wasn't requesting
+ enough space when the notebook tabs are visible.
+
+Sat Mar 1 01:59:35 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkpreview.c: Fixed a problem with 'gtk_preview_put' when the
+ image byte order is GDK_MSB_FIRST.
+
+ * gtksignal.c:
+ * gtksignal.h: Added 'gtk_signal_connect_after' and
+ 'gtk_signal_connect_object_after' functions. These connect signal
+ handlers which will run after the class function associated with
+ the signal.
+
+ * gtkstyle.c: Fixed a stupid bug in 'gtk_style_new_from_key' that
+ was causing twice as many styles to be created as necesary.
+
+ * gtkwidget.c: 'gtk_real_widget_size_allocate' erases the widgets
+ old allocation if it has the GTK_NO_WINDOW flag set.
+
+ * gtkwidget.c: 'gtk_real_widget_unmap' now erases the widget if it
+ has the GTK_NO_WINDOW flag set.
+
+ * gtklabel.c: Removed 'gtk_label_unmap' as similar functionality
+ was added to gtk_real_widget_unmap.
+
+ * gtkbin.c: Modified 'gtk_bin_map' and 'gtk_bin_unmap' so that it
+ erases and draws the widget if it has the GTK_NO_WINDOW flag set.
+
+ * gtkframe.c: Modified 'gtk_frame_size_allocate' so that it erases
+ the old allocation.
+
+Fri Feb 28 03:27:05 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: 'gtk_window_set_title' now changes the window title
+ if the window is already realized.
+
+ * gtkentry.c: 'gtk_entry_set_text' was emitting both a
+ "delete_text" and a "changed_text" signal. Modified so that it
+ only emits a "changed_text" signal.
+
+ * gtkpreview.c: Modified to work correctly on systems with MSB
+ byte order. The colormap for TRUE and DIRECT color displays is now
+ created if the default visual is not equal to the visual we are
+ using.
+
+ * gtkstyle.c: 'gtk_style_attach' and 'gtk_style_find' weren't
+ working properly in the presence of multiple colormaps are
+ different depth visuals.
+
+ * gtkcontainer.c: Massively improved focus traversal using tab and
+ arrow keys. It now uses the layout of the widgets to determine
+ where to move the focus to.
+
+Mon Feb 24 03:24:02 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c: Set the accelerator table field for menus when
+ they are created.
+
+ * gtkmenu.c:
+ * gtkmenu.h: Added a default accelerator table field to menus so
+ that runtime modification of accelerator keys in menus can work
+ better.
+
+ * gtkrange.c: 'gtk_range_default_{h,v}motion' had faulty logic for
+ deciding what to do when the slider was at the edge of the
+ trough. They previously didn't update the adjustment value event
+ if the value wasn't what it should be when the slider was at the
+ edge of the trough.
+
+ * gtkviewport.c: 'gtk_viewport_size_allocate' and
+ 'gtk_viewport_adjustment_value_changed' both had the potential for
+ performing a divide by 0. Checks are now in place to prevent this.
+
+ * gtkmenu.c: 'gtk_menu_map' now makes sure the menu lies on screen
+ if the position function is NULL.
+
+ * gtkentry.c: Modified selection handling. 'gtk_delete_selection'
+ actually removes the X selection now. 'gtk_entry_destroy' removes
+ the selection as well and relies on the change in "gdk.c" to make
+ sure the selection event will not be sent to a non-existant
+ window.
+
+ * gdk.c: Selection events are only passed on if the selection
+ owner is not NULL.
+
+ * gtkstyle.c: 'gtk_style_detach' and 'gtk_style_destroy' were not
+ destroying the black and white gc's.
+
+Sun Feb 23 19:17:56 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: 'gtk_window_size_request' was setting the window
+ hints. This was also being done in 'gtk_window_map', so the
+ instance being done in 'gtk_window_size_request' was removed.
+
+Fri Feb 21 01:04:01 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c: 'gtk_widget_draw' has to use the widgets allocated
+ position for the drawing rectangle when the widget has the
+ GTK_NO_WINDOW flag set.
+
+ * gtkwidget.c: In 'gtk_widget_init' the visual and colormap were
+ being directly compared against 'default_visual' and
+ 'default_colormap' instead of calling
+ 'gtk_widget_get_default_{visual,colormap}'.
+
+ * gdkrectangle.c: Amazing! There was a bug in the
+ 'gtk_rectangle_intersect' logic. Its been there for near eternity
+ and I never noticed.
+
+ * gtkpreview.c:
+ * gtkpreview.h: Created preview widget which allows drawing to an
+ rgb or grayscale buffer which is automatically displayed on the
+ screen. Performs dithering as necessary.
+
+Thu Feb 20 20:33:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkwindow.c: Modified the logic in 'gdk_window_new' which
+ determined when to add a window to the WM_COLORMAP_WINDOWS
+ property.
+
+Wed Feb 19 19:55:29 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkruler.c: 'gtk_ruler_make_pixmap' was always destroying the
+ old backing store and creating a new one even when it would create
+ a new one of exactly the same size as the old one.
+
+Tue Feb 18 18:32:10 1997 Peter Mattis <pmattis@localhost>
+
+ * gmem.c: 'g_mem_chunk_alloc' was incorrectly modifying the mem
+ areas free mem field when reallocating a previously freed
+ atom. This caused a fairly severe memory leak.
+
+ * gtkmenushell.c: 'gtk_menu_shell_button_release' had a bug in the
+ logic for deciding whether to initiate an X pointer grab or not
+ when the mouse button was released. It now only initiates a grab
+ if the mouse is released within an active menu item.
+
+Fri Feb 14 00:57:40 1997 Peter Mattis <pmattis@localhost>
+
+ * gtknotebook.c: Changed the look of notebook tabs slightly.
+
+ * gtkentry.c:
+ * gtkentry.h: Deleting an entry widget which is holding the X
+ selection presents some difficulties. The X selection must be
+ released, but the widget can't be destroyed until the
+ SELECTION_CLEAR event is received that the X server will send in
+ response to clearing the X selection. There are probably still
+ bugs in the current method of entry widget deletion when the X
+ selection is held.
+
+ * gtkmain.c: 'gtk_propagate_event' was not properly destroying the
+ toplevel window when receiving a key press event.
+
+ * gtkwidget.c: Setting a widget insensitive did not cause it to
+ redraw. It now does.
+
+Thu Feb 13 16:59:07 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkviewport.c: 'gtk_viewport_size_allocate' was allocating its
+ child widget an adjusted allocation. Since the actual scrolling
+ has handled by a subwindow this caused the child to be double
+ scrolled. Modified to always set the child allocations origin to
+ (0, 0).
+
+Wed Feb 12 01:06:48 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkentry.c: Text is now centered vertically. Previously it was
+ pushed up against the top. This problem was only evident when the
+ widget was allocated more vertical space than it requested.
+
+ * gtkfilesel.c: 'gtk_file_selection_key_press' was previously only
+ a stub for tab completion. The actual tab completion call had been
+ left out. (Oops!)
+
+Tue Feb 11 01:43:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtksignal.c: 'gtk_signal_disconnect_by_data' was going into a
+ loop and crashing. Bad logic. Fixed.
+
+ * gtkmain.c: An idle function which returns FALSE will be removed
+ from the list of idle functions. This makes the functioning of
+ idle functions and timeouts more similar.
+
+ * gtkentry.c: 'gtk_entry_get_text' now returns an empty string
+ when the actual text is NULL. This allows "stupid" programs to use
+ the value returned by 'gtk_entry_get_text' blindly (without
+ checking to see if its NULL).
+
+ * gtkradiobutton.c: Modified 'gtk_radio_button_clicked' so that
+ 'gtk_toggle_button_toggled' is called _after_ the widget state is
+ changed.
+
+ * gtksignal.c:
+ * gtksignal.h: Added 'gtk_signal_name' which returns the character
+ string name for a given signal number.
+
+ * gtkwidget.c: 'gtk_widget_set_parent' checks to see if the widget
+ is now "anchored" through the parent chain to a widget which is
+ GTK_ANCHORED. If it is, then it changes the widgets style using
+ 'gtk_rc_get_style' and recursively performs the same operation on
+ the widgets children. This is necessary is 'gtk_rc_get_style' only
+ works properly on "anchored" widgets.
+
+ * gtkwindow.c: Modified GTK_WIN_POS logic so that it is only used
+ immediately after the window has been shown.
+
+ * gtkmenu.c: 'gtk_menu_key_press'. Can now change menu item
+ accelerator keys on the fly. Why? Why not. Cool/useless feature of
+ the day.
+
+ * gtkmenuitem.c: Accelerator key drawing. Somehow that never got
+ finished. (Oops!)
+
+ * gtkdrawingarea.c: 'gtk_drawing_area_size_allocate' was not
+ actually installed during 'gtk_drawing_area_class_init'. (Oops!)
+
+ * gtkframe.c: 'gtk_frame_size_request' fixed size requisition
+ problem caused by unsigned arithmetic.
+
+ * gtkwindow.c: Modified window widget so that it only uses the
+ widget uposition auxiliary information immediately after it has
+ been shown. This prevents the annoying bug which can cause a
+ uposition'ed window to jump back to its original position after
+ the user moves it.
+
+ * gtkwidget.c: Need to ref and unref style in
+ 'gtk_widget_{push,pop}_style' to make sure that a style on the
+ style stack is not destroyed.
+
+ * gtktogglebutton.c: 'gtk_toggle_button_set_state' now calls
+ gtk_button_clicked to actually change the state of the
+ button. In this way, radio buttons can now perform the appropriate
+ actions when the toggle button state is set.
+
+Mon Feb 10 00:27:39 1997 Peter Mattis <pmattis@localhost>
+
+ * gtklist.c: 'gtk_list_select_item' and 'gtk_list_unselect_item'
+ were casting a GList* variable to a a GtkWidget* variable. Bad bad
+ bad. (Tim Janik).
+
+ * gtksignal.c: Modified 'gtk_signal_connect' and
+ 'gtk_signal_connect_object' to warn when a signal type cannot be
+ found.
+
+Sun Feb 9 00:15:30 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkoptionmenu.c:
+ * gtkoptionmenu.h: Changed option menus back to being derived from
+ buttons. This fixes up some screwiness with their user
+ interaction.
+
+ * gtkwindow.c: Modified key press handler to support focus
+ traversal.
+
+ * gtkcontainer.c:
+ * gtkcontainer.h: Added default focus traversal back in.
+
+Sat Feb 8 10:44:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkviewport.h:
+ * gtkviewport.c: Massively sped up viewport scrolling. Used to be
+ reallocating child's size (offset) each time a scrollbar
+ moved. Now a subwindow is moved. All the children are moved
+ automatically by moving the subwindow. Much much much faster.
+
+Tue Feb 4 00:20:44 1997 Peter Mattis <pmattis@localhost>
+
+ * gtree.c: Changed 'g_tree_node_search' to use a loop instead of
+ recursion.
+
+Mon Feb 3 11:30:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkbutton.c: Removed 'parent_destroy' global and replaced it
+ with 'parent_class' global to reflect style used in other
+ widgets.
+
+ * gtknotebook.c: Tab labels were being allocated less than their
+ requested size.
+
+ * gtkrange.c:
+ * gtkrange.h: Moved the "digits" field of scales into the range
+ type. The adjustment value for scales is truncated to the number
+ of visible digits instead of being left untouched.
+
+ * gtree.c: Fixed a bug in the AVL tree implementation. Single
+ rotations were always being performed during insertion. It is
+ sometimes necessary to perform a double rotation.
+
+ * gtklabel.c: Modified 'gtk_label_expose' to only draw the label
+ when the allocated space is greater than or equal to the requested
+ space.
+
+ * gtklabel.c: Added call to 'gtk_widget_unmap' to
+ 'gtk_label_destroy' in order for the label to redraw correctly
+ (erase itself) when destroyed.
+
+ * gtklabel.c: Added 'gtk_label_unmap' call which erases the labels
+ allocation when it gets unmapped.
+
+ * *.h: Removed a few remaining instances of using "class" as a
+ parameter name. (Causes problems for C++).
+
+Fri Jan 31 12:26:50 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcontainer.c: 'gtk_container_enable_resize' needs to call
+ 'gtk_container_check_resize' instead of
+ 'gtk_container_need_resize'.
+
+ * gtkwidget.c: 'gtk_real_widget_show' now maps the widget if its
+ parent is mapped.
+
+ * gtkscrolledwindow.c: Fixed size allocation when the scrollbar
+ policy's are GTK_POLICY_AUTOMATIC. Doing it correctly is harder
+ than I originally thought.
+
+ * gtklist.c: Added 'gtk_list_child_position' to determine the
+ integer position in a list of a child. Filled in the
+ 'gtk_list_item_select' and 'gtk_list_item_unselect' stubs.
+
+Thu Jan 30 16:08:06 1997 Peter Mattis <pmattis@localhost>
+
+ * gmem.c: Changed the implementation of G_ALLOC_AND_FREE mem
+ chunks. They used to allocate SIZEOF_VOID_P extra bytes per atom
+ in order to keep track of which mem area they were allocated
+ from. Now the mem area is determined by searching through an AVL
+ tree of the mem areas for a mem chunk and comparing memory
+ locations. A little slower, but makes G_ALLOC_AND_FREE mem chunks
+ much more attractive.
+
+ * gtree.c: Added an AVL tree implementation to glib.
+
+ * gtksignal.c:
+ * gstring.c: va_arg (arg_list, {char, short}) is
+ invalid. Arguments passed in a variable argument list are
+ promoted. ({char, short}->int). Seemed to work ok before under
+ Linux. Crashed under FreeBSD.
+
+Tue Jan 28 02:27:51 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkwindow.c: Fixed a major slowdown apparent in the file
+ selection dialog which was caused by calling
+ 'gtk_window_add_colormap_windows' way way way too often.
+
+ * *.c: Many widgets called 'gtk_container_need_resize' when
+ something internal changed which would cause the widget to grow or
+ shrink. The assumption was made that the widget would change size
+ and an expose event would be generated. This happens "most" of the
+ time. But its possible for certain widgets to change size without
+ generating expose events, or for its internal geometry to change
+ without a change of size which would mean no expose event was
+ generated. So a wrapper function called
+ 'gtk_container_check_resize' was created and
+ 'gtk_container_need_resize' was modified so that it returns FALSE
+ if a resize was actually generated and TRUE if nothing
+ changed. This allows 'gtk_container_check_resize' to initiate a
+ 'gtk_widget_size_allocate' and 'gtk_widget_draw' to emulate the
+ expose event.
+
+Sat Jan 25 14:17:44 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmain.c: Fixed a bug with propogating key press events. The
+ events were sent 2 times to the toplevel windows which caused the
+ focus widget to be activated twice when the space bar was pressed.
+
+ * */configure.in:
+ * */Makefile.am: Added support for libtool and removed the old
+ shared library configuration craziness.
+
+Fri Jan 24 12:59:22 1997 Peter Mattis <pmattis@localhost>
+
+ * gtktext.c:
+ * gtktext.h: Josh's fixes and additions to the text widget.
+
+ * gtkfill.c:
+ * gtkfill.h: Filler widget useful for filling space in a
+ table. Can specify a minimum size. Used by the canvas widget.
+
+ * gtknotebook.c:
+ * gtknotebook.h: Made outline of notebook widget.
+
+ * gtkcanvas.c:
+ * gtkcanvas.h: Started canvas widget. A composite of 2 rulers (w/
+ an origin), 2 scrolllbars. Guides, grids, snap to.
+
+Sun Jan 19 18:26:45 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkdialog.c:
+ * gtkdialog.h: Created dialog widget which creates a standard
+ looking dialog with buttons along the button and a separator.
+
+ * gtkxid.c: Generalized the window table code for looking up a gdk
+ window based on an XID to work for any XID and a piece of
+ data. Can now look up gdk fonts based on their XID.
+
+ * gtkruler.c:
+ * gtkruler.h:
+ * gtkhruler.c:
+ * gtkhruler.h:
+ * gtkvruler.c:
+ * gtkvruler.h: Started conversion of the ruler widget.
+
+ * gtktext.c:
+ * gtktext.h: Started conversion of the text widget. Scrolling
+ doesn't work.
+
+ * gtkmain.c: Fixed a fairly major bug. The event widget needs to
+ be in a call for the entire duration of handling an event. Not
+ just for when the event widget itself is handling the event.
+
+ * gtkfilesel.c: Fixed up some bugs with resizing.
+
+Fri Jan 10 14:18:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c:
+ * gtkwidget.h:
+ * gtkentry.c:
+ * gtkentry.h: Support for selections.
+
+ * gdkselection.c:
+ * gdk.c:
+ * gdktypes.h:
+ * gdk.h: Gdk support for X selections. Currently only text
+ selections are supported.
+
+ * gtksignal.c: Fixed a major bug which occurred when destroying an
+ object. Memory was being written to after it was freed.
+
+ * gtkfilesel.c:
+ * gtkfilesel.h: Hooked up more functionality to the file selection
+ dialog.
+
+Wed Jan 8 18:13:53 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkfilesel.c:
+ * gtkfilesel.h: Mostly converted old file selection dialog
+ widget. The widget is derived from the GtkWindow class and is
+ quite a bit simpler in the widget code.
+
+ * gtkwidget.c: Fixed 'gtk_widget_grab_focus' and
+ 'gtk_widget_grab_default' to check that the toplevel widget is a
+ type of window (which includes classes derived from windows).
+
+Tue Jan 7 01:12:32 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: Was calling 'gtk_window_resize' twice in a
+ row...why?
+
+ * gtksignal.c:
+ * gtksignal.h:
+ * *.c: Changed 'gtk_signal_new' so that the class function that is
+ called when the signal is emitted can be called either before,
+ after or both before and after the calling of any signal
+ handlers.
+
+ * gtkobject.c:
+ * gtkobject.h: Added 'object_data' mechanism for storing data
+ associated with a character string key in objects. Removed
+ 'user_data' field of objects and changed
+ 'gtk_object_{get,set}_user_data' to use the object data
+ mechanism. Removed 'handlers' field of objects.
+
+ * gtkwidget.c:
+ * gtkwidget.h:
+ * gtkwindow.c: Modified aux info mechanism to use object data
+ mechanism.
+
+ * gtksignal.c: Modified signal mechanism to use object data
+ mechanism instead of 'handlers' field.
+
+
+Mon Jan 6 15:10:16 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c: Fixed up button press handling so as to conform
+ more closely to that used by Motif.
+
+Wed Jan 1 21:27:17 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenu.c:
+ * gtkmenu.h:
+ * gtkmenubar.c:
+ * gtkmenubar.h:
+ * gtkmenushell.c:
+ * gtkmenushell.h: Reorganization of menu-ing code so that code
+ duplication is reduced. The menu shell now contains most of the
+ code for menu-ing interaction while menus and menubars simply layout
+ their child menu items in the appropriate place.
+
+Sun Dec 29 17:48:18 1996 Peter Mattis <pmattis@localhost>
+
+ * gtkmenu.c:
+ * gtkmenubar.c:
+ * gtkmenuitem.h:
+ * gtkmenuitem.c: Modifications so that menu item accelerators and
+ the submenu indicator are drawn correctly and the correct amount
+ of space is allocated.
+
+Sat Dec 28 00:32:13 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkmenufactory.h:
+ * gtkmenufactory.c: Started menu factories as an easy method to
+ create and manipulate menus.
+
+Fri Dec 27 13:17:34 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkmenu.c:
+ * gtkmenu.h:
+ * gtkmenubar.c:
+ * gtkmenubar.h:
+ * gtkmenuitem.c:
+ * gtkmenuitem.h:
+ * gtkmenushell.c:
+ * gtkmenushell.h: Implemented basic menu functionality. Menubars
+ and popup menus work. Submenus work. (Much left to be done).
+
+Wed Dec 18 15:27:05 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtktypeutils.h:
+ * gtktypeutils.c: Added 'gtk_type_from_name' which returns a type
+ identifier given a type name. Implemented using a second hash
+ table keyed by type names.
+
+ * gtkbutton.c:
+ * gtktogglebutton.c: Fixed very small messed-up drawing bug when a
+ button loses its focus.
+
+ * gtkwidget.h:
+ * gtkwidget.c:
+ * gtkbutton.c:
+ * gtkwindow.c: Added default button handling. Default buttons now
+ draw correctly and pressing return or enter causes the default
+ button (if one exists) to be activated.
+
+Tue Dec 17 19:32:21 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkhscale.c:
+ * gtkvscale.c: Overrode 'draw_slider' method of ranges in order to
+ draw the slider of scales with a line in them so as to be closer
+ to the Motif look-and-feel.
+
+ * gtkwindow.c: Modified 'gtk_window_focus_in_event' so that focus
+ in events are only handled when the window is visible. Fixes a bug
+ where spurious focus in events get sent when a window is being
+ hidden.
+
+ * gtkwidget.h: Added 'activate_signal' field to the GtkWidgetClass
+ structure. Added 'gtk_widget_activate' call to emit the activate
+ signal for a widget if it is non-zero.
+
+Tue Dec 10 15:59:45 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkwidget.c: 'gtk_widget_set_name' oops in strdup'ing the old
+ "widget->name" instead of the new one we are setting.
+
+ * gtkrc.c: 'gtk_rc_widget_path' changed to use
+ 'gtk_widget_get_name' instead of accessing the "widget->name"
+ field directly.
+
+ * gtkwidget.c: Added 'gtk_widget_get_name' function which returns
+ the widgets name if it exists and the widgets type name if it does
+ not.
+
+ * gtkcheckbutton.c: Added 'gtk_check_button_draw'
+ function. Modified 'gtk_check_button_expose' to pass an expose
+ event to child instead of callings its draw function.
+
+ * gtkentry.c: 'gtk_entry_draw_text' why was "+1" being added to
+ the font->ascent to calculate the font position? This was wrong
+ and caused some characters in fonts to be clipped. (Notably "g").
+
+ * gtkentry.c: 'gtk_entry_realize' specify GTK_BUTTON1_MOTION_MASK
+ and GTK_POINTER_MOTION_HINT_MASK for _both_ windows.
+
+ * gtkmain.c: 'gtk_propagate_event' needs to set the GTK_IN_CALL
+ flag for the object before calling 'gtk_widget_event' and needs to
+ destroy the object if necessary after 'gtk_widget_event' returns.
+
+ * gtkradiobutton.c: 'gtk_radio_button_clicked' needs to call
+ 'gtk_toggle_button_toggled' when the currently active button is
+ toggled.
+
+ * gtkwidget.c: 'gtk_real_widget_hide' needs to call
+ 'gtk_widget_unmap' if the widget is currently mapped.
+
+ * gtkwindow.c: Prevent automatic resizing after the user has
+ specified a new window size. Add 'handling_resize' flag to
+ windows.
+
+ * gtkscrolledwindow.c: Implement the GTK_POLICY_AUTOMATIC
+ scrollbar policy. Need to connect to the adjustments 'changed'
+ signal and notice when the scrollbars aren't in use.
+
+ * gtkcontainer.c: 'gtk_container_init' must set 'auto_resize' and
+ 'need_resize' fields to TRUE and FALSE respectively.
+
+ * gtkwidget.c: 'gtk_widget_set_parent' must all set a widgets state
+ to its parents state.
+
+Sun Dec 1 01:31:01 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>

+ to fix some viewport bugs
+
+Mon Nov 17 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtkwidget.c: gtk-ajaborsk-971016-2
+ A little patch again to prevent user to use gtk_widget_set_events()
+ when a widget is already realized.
+ In this case, the gtk_widget_set_events() doesn't work.
+
+Mon Nov 17 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtkwindow.c: gtk-ajaborsk-971016-1
+ This small patch correct position for GTK_WIN_POS_CENTER and
+ GTK_WIN_POS_MOUSE GtkWindow positions.
+
+Sat Nov 15 1997 Jay Painter <jpaint@serv.net>
+ * gdk/gdkgc.c: added function gdk_gc_set_clip_rectangle
+ * gdk/gdk.h: header for above

+ * gdk/gdkpixmap.c: Patrice Fortier's patch for transparent pixmaps.
+ * gdk/gdk.h:
+ gdk/gdkdraw.c: Patrice Fortier's patch to add pixel draw function.
+
+Sun Nov 9 1997 Jay Painter <jpaint@serv.net>
+ * Fixed problems with makefiles relating to the bug
+ which required glib to be installed.
+ * Fixed makefiles to incluce the xpm's in gtk+/gtk needed
+ for testgtk.
+ * Updated gtk+ and gtk+/glib to libtool-1.0f
+
+Fri Nov 7 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtktext.c: return char_widths[ch & 0xff]; in line 2152
+
+Thr Nov 5 1997 Jay Painter <jpaint@serv.net>
+ * gtk/testgtk.c: added drag and drop test, removed the test hack
+ from the button test
+
+Tue Nov 4 08:28:57 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gtk/gtkmain.c (gtk_handle_idle): Patch from David Mosberger to
+ avoid crashes when handling idle function (this manifested itself
+ in the Umax and Microtek backends in SANE.
+
+Sun Nov 2 07:34:56 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtkfilesel.c: Small fixes about a segmentation viaolation
+ cause by a double click in the directoy list (introduced by my
+ previous changes).
+
+ * gtk/gtklist.c: Small fixes to gtk_list_add() and gtk_list_remove().
+
+ * gtk/testgtk.c (list_add): Applied Stefan Wille's patch to make this
+ function do something ;).
+
+Fri Oct 31 Jay Painter <jpaint@serv.net>
+ *gdk/gdk.c: reformatted DND code for GTK coding standards
+ *gdk/gdkwindow.c: changed memory allocation for DND to q_mem stuff
+
+Thu Oct 30 Jay Painter <jpaint@serv.net>
+ * gdk/gdkwindow.c:
+ * gdk/gdk/gdk.h:
+ * gtk/gtkwidget.h:

+
+ * gdk/gdkwindow:
+ * gdk/gdk.h:
+ * gtk/gtkwidget.h:
+ * gtk/gtkwidget.c: reformatted the DND code to conform to GTK
+ coding standards
+
+ * gtk/testgtk: massive fixes, SW's shaped window example
+
+Thu Oct 30 07:33:27 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtklistitem.c (gtk_real_list_item_toggle): applied Johannes
+ Keukelaar's <johannes@nada.kth.se> patch for keyboard support in
+ GtkList widgets.
+
+ * gtk/gtkfilesel.c: adapted dir and file list selection
+ behaviour to deal with keyboard selections. this is a little
+ bit tricky: in the dir list it just changes the entrys value on a one
+ button press. but on a keyboard selection via gtk_widget_activate() it
+ does a new population (likewise on a double click) as this seems more
+ obvious.
+
+1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * gdk/gdkcolor.c (gdk_colormap_get_system): Initialize
+ private->ref_count.
+
+Wed Oct 22 09:47:43 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtkwindow.c (gtk_window_key_release_event): Fixed a stupid
+ bug that caused the key_release_event to be propagated twice.
+
+Sun Oct 12 11:01:43 1997 Tim Janik <timj@psynet.net>
+
+ * acconfig.h:
+ * configure.in:
+ * gdk/gdkimage.c: Added configure check for IPC_RMID_DEFERRED_RELEASE,
+ because shmat() fails after a shmctl(..., IPC_RMID,...) for OSF1 V3.2,
+ SunOS 4.1.1, 5.5, 5.5.1, 5.6, IRIX 5.2 and 6.2.
+
+Mon Oct 6 11:59:07 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gdk/gdk.c (gdk_event_translate): In line 1693, fixed typo that
+ would cause motion notify events not to be delivered.
+
+Sun Oct 5 18:15:06 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gtk/gtkrc.c (gtk_rc_parse_bg_pixmap): Changed strdup() for
+ g_strdup().
+
+Wed Sep 24 17:16:34 1997 Peter Mattis <pmattis@bjork.inktomi.com>
+
+ * configure.in: Fixed a stupid error in the test for libXext that
+ would cause it to fail if X_EXTRA_LIBS was not empty.
+
+ * gtk/gtkmain.h (gtk-timj-970919.patch):
+ * gtk/gtkmain.c (gtk-timj-970919.patch): new function
+ `gtk_idle_remove_by_data' to remove all idle callbacks that take a
+ specific piece of data as argument. (gtk_get_current_event):
+ remove idles through gtk_idle_remove_by_data.
+
+ * gtk/gtkwidget.c (gtk-timj-970919.patch):
+ (gtk_widget_destroy): remove pending idles for
+ widgets that have GTK_REDRAW_PENDING or GTK_RESIZE_PENDING and
+ GTK_ANCHORED set (only anchored widgets can have a resize queue
+ handler pending). widgets that have GTK_RESIZE_NEEDED will be removed
+ from their anchored toplevels `resize_widgets' list.
+
+ (gtk_widget_queue_draw): let the widget remember the queue handler
+ tag (through `redraw_handler_key') for later call to `gtk_idle_remove'.
+
+ (gtk_widget_queue_resize): let the widget remember the queue handler
+ tag (through `resize_handler_key') for later call to `gtk_idle_remove'.
+ corrected referencing the toplevel widget for which the handler is
+ pending. if a widget is added to the `resize_widgets' list of a
+ toplevel widget, GTK_RESIZE_NEEDED is set and it's referenced.
+
+ (gtk_real_widget_queue_resize): on the deletion of the `resize_widgets'
+ list, unset GTK_RESIZE_NEEDED and unreference the removed widgets.
+
+ * gtk/gtkwindow.c (gtk-timj-970919.patch):
+ (gtk_real_window_move_resize): move `resize_containers = NULL'
+ initialization out of if-statement.
+ while stepping through the `resize_widgets' list, unreference the
+ widgets and clear GTK_RESIZE_NEEDED. if a widget realy needs are
+ resize, they are flagged through GTK_RESIZE_NEEDED now (instead of
+ GTK_RESIZE_PENDING, as this is indicative for a pending handler).
+ added checks to provide segfaulting if a widgets parent pointer
+ is NULL (e.g. on toplevel widgets that have GTK_RESIZE_NEEDED set).
+
+Tue Sep 23 13:23:27 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gdk/gdkimage.c: Applied Tim Janik's patch to mark shm segments
+ as IPC_RMID so that they are automatically removed always.
+
+ * gdk/gdkfont.c: Removed casts from lvalues.
+
+ * gtk/gtkmain.c: Removed GTK_RETLOC_*() (which do a cast) from lvalues.
+
+ * gtk/gtkaccelerator.c (gtk_accelerator_table_remove): Added
+ "const" to the accelerator_key param to be consistent with the
+ declaration in gtkaccelerator.h. The const is not useful in this
+ case, anyway.
+
+Tue Sep 16 13:11:06 1997 Peter Mattis <pmattis@bjork.inktomi.com>
+
+ * gtkpreview.c: Andrew Logan Kieschnick's change to eliminate
+ round-off error when gamma is set to 1.0.
+
+ * gtkrange.c:
+ * gtkviewport.c: Jay Painter's changes to modify the way in which
+ viewports resize.
+
+ * gdkinput.c:
+ * gdkinputgxi.h:
+ * gdkinputxfree.h:
+ * gtk/Makefile.am:
+ * gtk.h:
+ * gtkeventbox.c:
+ * gtkeventbox.h: Owen Taylor's event box widget and fixes for X
+ input support (that I had broken).
+
+ * gdk.h:
+ * gdkwindow.c:
+ * gtksignal.h:
+ * gtksignal.c: Elliot Lee's changes to support Objective C. (id is
+ apparently a reserved word in Objective C).
+
+Sun Sep 14 22:33:15 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c (gtk_widget_queue_resize): If the toplevel container
+ is invisible we simply call "gtk_container_need_resize" on
+ it. This fixes a bug with option menus not redrawing correctly.
+
+ * gtkmenuitem.c (gtk_menu_item_enter): (gtk_menu_item_leave):
+ These functions now simply pass the event on to their parent. This
+ is necessary for menus to work properly due to the change in how
+ grabs are dealts with.
+
+ * gtkwindow.c (gtk_real_window_move_resize): Fixed a bug that
+ caused the GTK_RESIZE_PENDING flag to not be unset in some cases.
+
+Fri Sep 5 20:49:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
+
+ Bug fixes:
+
+ * Makefile.am: Added PATCHES to EXTRA_DIST.
+ * gtk/gtkpixmap.c (gtk_pixmap_new): Move the "pixmap != NULL" test
+ after the allocation of the pixmap.
+
+ To shut up the compiler:
+
+ * gtk/gtkfilesel.c (get_pwdb): Initialize home_dir.
+ * gtk/gtkmain.c (gtk_init): Replace comments around calls to
+ g_set_*_handler with "if (0)".
+ * gtk/gtkrc.c (gtk_rc_get_token): Initialize hex_number and
+ float_number.
+ * gtk/gtkwindow.c (gtk_window_key_press_event): Initialize
+ direction.
+
+ Changes to the type system in gtk/:
+
+ * Makefile.am: Added gtktypebuiltins.h to gtkinclude_HEADERS.
+ Added gtk.defs, runelisp, gentypeinfo.el and gtktypebuiltins.c to
+ EXTRA_DIST. Added rules to generate gtktypebuiltins.* from
+ gtk.defs.
+
+ * runelisp, gentypeinfo.el, gtk.defs: New files.
+
+ * gtkaccelerator.c, gtkaccelerator.h (gtk_accelerator_table_ref):
+ Return the table so that this function can be used as the `copy'
+ function for GTK_TYPE_BOXED values.
+ * gtkstyle.c, gtkstyle.h (gtk_style_ref): Likewise.
+
+ * gtkenums.h: Removed GtkArgType enum.
+
+ * gtkmain.c (gtk_init): Call gtk_type_init to initialize the type
+ system.
+
+ * gtkobject.c (gtk_object_init_type): New function to take over
+ for gtk_object_get_type. (gtk_object_get_type): Just return the
+ constant GTK_TYPE_OBJECT. (gtk_object_collect_args): Do the right
+ thing for the new GTK_TYPE_* types.
+ * gtksignal.c (gtk_params_get): Likewise.
+
+ * gtktypeutils.c: (gtk_type_init_builtin_types): New
+ function. (gtk_type_init): Call it. Also made non-static.
+ (gtk_type_unique): The allocation scheme for numerical ids has
+ changed: The low 8 bits hold the appropriate GtkFundamentalType of
+ a type, the rest is a globally unique sequence number.
+ (gtk_type_hash): Use the sequence number of a key to hash it.
+ (gtk_type_register_builtin): New function.
+
+ * gtktypeutils.h: (GtkFundamentalType): New enumeration of the
+ fundamental types. (GTK_TYPE_MAKE, GTK_FUNDAMENTAL_TYPE,
+ GTK_TYPE_SEQNO): New macros to work with the new id scheme.
+ (GtkArg): Added fields for new types and renamed old ones. GtkArg
+ should now be a mostly opaque structure, except name and type.
+ (GTK_VALUE_*): New macros to access the values of a GtkArg.
+ (GTK_RETLOC_*): New macros to access the location of a return
+ value that is contained in a GtkArg. * gtktypebuiltins.h: New
+ file to access the typeids of the builtin types.
+
+ * gtkwidget.h (GTK_TYPE_WIDGET): New macro to access the type id
+ of the widget class.
+
+ Thru out: Changed GTK_ARG_* to the appropriate GTK_TYPE_*.
+ Changed access to GtkArg structure to the appropriate GTK_VALUE_*
+ or GTK_RETLOC_* macro. Changed GtkArgType to GtkType. Changed
+ some guints to GtkType.
+
+ General changes in gtk/ to support interpreters:
+
+ * gtkradiobutton.c (gtk_radio_button_new_from_widget,
+ gtk_radio_button_new_with_label_from_widget): New functions.
+
+ * gtksignal.c (gtk_signal_connect_no_marshal): New function.
+ (struct _GtkHandler): Added no_marshal and destroy_func fields.
+ (gtk_signal_handler_new): Initialize them.
+ (gtk_signal_connect_by_type): Added no_marshal and destroy_func
+ arguments. Changed all callers.
+ (gtk_signal_destroy): Invoke destroy_func if there is one and the
+ global destroy func does not apply. (gtk_handlers_run): If the
+ handler has no_marshal set, call its function directly without
+ going thru the signal's marshaller.
+
+Wed Sep 3 09:56:22 1997 RHS Linux User <pmattis@bjork.inktomi.com>
+
+ * gtkrange.c: Changed the way the range control focus was drawn so
+ that the range control is drawn correctly when it does not have
+ the focus.
+
+Tue Sep 2 17:41:17 1997 RHS Linux User <pmattis@bjork.inktomi.com>
+
+ * gtkwidget.c: 'gtk_real_widget_queue_resize' should only remove
+ the "resize_widgets" if another resize is not pending.
+
+Mon Sep 1 18:28:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmain.c: Changed the way GDK_DELETE events are handled. Only,
+ if 'gtk_widget_event' returns TRUE is the widget destroyed. By
+ default, 'gtk_widget_event' will return FALSE causing the window
+ to not be destroyed. This prevents segfaults in the GIMP and other
+ programs that do not correctly handle GDK_DELETE events.
+
+ * gtkmain.c: Added modal dialog support by allowing events
+ destined for a child of the grab widget to go to the child instead
+ of the grab widget. (Added 'gtk_widget_is_ancestor' to determine
+ the relationship between the grab widget and the event widget).
+
+ * *.[ch]: Incorprated a whole mess of patches. (Started keeping
+ the ChangeLog up to date again).
+
+Thu Jun 5 17:22:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c:
+ * gtkmenufactory.h: Added 'gtk_menu_factory_remove_*'
+ calls. Removing entries/paths causes the associated widgets to be
+ destroyed.
+
+ * gtkwidget.c:
+ * gtkwidget.h: Calling 'gtk_widget_set_style' is used as an
+ indication that the programmer specifically wants that style to be
+ used. RC-style substitution is disabled for the widget after such
+ a call.
+
+ * gtkpixmap.c:
+ * gtkpixmap.h:
+ * gtkimage.c:
+ * gtkimage.h: Changed to use clip mask and a single pixmap (or
+ image) to deal with transparent areas.
+
+ * gdkpixmap.c: Modified xpm loading routines to optionally return
+ a clip mask.
+
+ * gdkgc.c:
+ * gdkdraw.c:
+ * gdktypes.h: Modifications to allow clip masks to be used with
+ gc's. Clip masks are bitmaps that specify drawable regions.
+
+Thu May 1 03:11:51 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkscrolledwindow.c: Scrolled windows need to have the
+ GTK_NO_WINDOW flag set. Not having it set caused an obscure
+ redrawing bug.
+
+Wed Apr 30 12:38:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkhruler.c:
+ * gtkvruler.c: Fixed a small bug that caused the indicator to be
+ positioned slightly off.
+
+Sun Apr 27 14:28:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c:
+ * gtkmenushell.h:
+ * gtkmenu.c:
+ * gtkmenu.h: Changes so that if a menu is popped up there is a
+ timeout period during which a menu item will not be activated and
+ if the mouse button is released in that period the menu will stay
+ popped up.
+
+ * gtkcurve.c:
+ * gtkcurve.h: Included curve widget courtesy of David
+ Mosberger-Tang (davidm@azstarnet.com).
+
+ * gtkentry.c:
+ * gtkentry.h: Changed "insert" and "delete" signals to
+ "insert_text" and "delete_text" respectively. (The symbol "delete"
+ cannot be used since it is a C++ reserved word).
+
+Sat Apr 19 01:43:49 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c: A path which ends in "<nothing>" will cause an
+ invisible (hidden) menu entry to be created. This is useful for
+ setting an accelerator key for which a corresponding menu entry is
+ not desired.
+
+ * gtktooltips.c: Fixed some problems with destruction of the
+ active tip widget not properly updating the tooltips data
+ structures.
+
+Fri Apr 18 15:09:45 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcontainer.c:
+ * gtklist.c:
+ * gtkwidget.c:
+ * gtkwidget.h: Patch from Owen Taylor (owt1@cornell.edu) which
+ fixes problems with destruction of objects and with destruction of
+ objects which hold the focus.
+
+Thu Apr 17 11:29:15 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c: Incorrect logic in
+ 'gtk_menu_shell_button_release' for deciding when a menu should
+ stay popped up when the mouse button is released.
+
+ * *.c: Miscellaneous fixes from folks on the net.
+
+Tue Apr 15 02:43:17 1997 Peter Mattis <pmattis@localhost>
+
+ * *.c:
+ * gtkwidget.h: Added GTK_BASIC widget flag which when set
+ specifies a widget as "basic". A "basic" widget is one which
+ doesn't take input events. For example, labels, pixmaps, boxes,
+ tables, alignments, etc.
+
+Sat Apr 12 15:23:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcolorsel.c: Add "#include <math.h>" to define M_PI.
+
+ * gtksignal.c: Fixed a bug in 'gtk_signal_emit' which showed up
+ because of the new cast checking macros. The 'object' was being
+ accessed after it had been destroyed.
+
+ * gtkoptionmenu.c: Fixed bug with using 'GTK_BIN' instead of
+ 'GTK_BUTTON' which showed up because of the new cast checking
+ macros.
+
+ * *.h: 'GTK_CHECK_CAST', 'GTK_CHECK_CLASS_CAST' and
+ 'GTK_CHECK_TYPE' used by standard widget macros everywhere.
+
+Wed Apr 9 00:54:17 1997 Peter Mattis <pmattis@localhost>
+
+ * docs/gtk.texi: Started further work on documentation. Major
+ changes and additions are being made.
+
+ * gtkarrow.c:
+ * gtkarrow.h: Removed function 'gtk_arrow_get'.
+
+ * gtkcontainer.c: 'gtk_container_check_resize' no performs
+ additional checking to account for the case where the containers
+ allocation is no longer sufficient because its parent (or its
+ parents parent, etc.) needs to resize its children.
+
+Tue Apr 8 21:15:50 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkstyle.c: Fixed a bug in 'gtk_style_init' in which the font
+ was not ref'd (via 'gdk_font_ref'), but was free'd (via in
+ 'gdk_font_free') in 'gtk_style_destroy'. (David
+ Mosberger-Tang). Also cleaned up 'gtk_style_destroy' while I was
+ at it.
+
+ * gtkmain.c: Fixed a bug in 'gtk_propogate_event' which caused
+ entry widgets (and probably other widgets) not to be destroyed in
+ some instances.
+
+Mon Apr 7 01:20:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkentry.c:
+ * gtkentry.h: Changed the "insert_text", "delete_text" and
+ "changed_text" signals to "insert", "delete", and "changed"
+ respectively. They really should have been named this way
+ originally except the previous signal mechanism prevented
+ duplicate signal names. ("changed" is also used by adjustments).
+
+ * gtkradiomenuitem.c:
+ * gtkradiomenuitem.h: New widget.
+
+ * gtkcheckmenuitem.c:
+ * gtkcheckmenuitem.h: New widget.
+
+ * gtksignal.c: Modified 'gtk_signal_lookup' to require an object
+ type to be passed as a parameter. In addition, signals are now
+ only needed to be uniquely defined in their branch of the class
+ hierarchy. This allows the same signal name to be used in two
+ different branches of the class hierarchy. For instance, the
+ "changed" signal is used both by adjustments and entries...in
+ different ways!
+
+ * gtktypeutils.c: Added 'gtk_type_parent' which returns the parent
+ type for a given type.
+
+Sun Apr 6 22:08:35 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c: If a widget is set insensitive it loses the focus
+ if it had it.
+
+ * gtkcontainer.c: Insensitive widgets no longer participate in tab
+ traversal.
+
+ * gtkscrolledwindow.c: The "viewport" child is now destroyed and a
+ container class "foreach" function was written (which fixes the
+ sensitivity bug).
+
+Sat Apr 5 14:25:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkhscrollbar.c:
+ * gtkvscrollbar.c: Fixed trough size allocation bug.
+
+ * gtkhscale.c:
+ * gtkvscale.c: Fixed trough size allocation and position bug that
+ showed up when scales were placed in notebooks.
+
+Thu Mar 27 17:45:54 1997 David Mosberger-Tang <davidm@azstarnet.com>
+
+ * gtk/gtkmain.c (gtk_handle_idle): Fix appending pending_idles to
+ idle_functions so it works even when idle_functions is empty.
+
+Sat Mar 15 14:15:59 1997 Peter Mattis <pmattis@localhost>
+
+ * *.[ch]: Moved '*_class_init' and '*_init' function declarations
+ for widgets into the source file as those functions no longer had
+ to be public.
+
+ * gtkcheckbutton.c: Fixed redrawing of check button.
+
+ * gtkframe.c: Fixed redrawing of frame when the shadow type is
+ changed.
+
+Sat Mar 8 15:19:23 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkimage.c: Fixed a stupid bug with 'gdk_image_new' which
+ potentially added a NULL image to "image_list" and caused problems
+ when 'gdk_image_exit' was called.
+
+Wed Mar 5 00:40:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkpreview.c: Massively changed the colormap handling used by
+ the preview widget. Gray previews are now dithered. A single
+ visual and colormap is shared by the color and gray previews. A
+ GTK_PREVIEW_INFO property is installed on the root window in
+ certain cases to allow multiple GTK programs to share the system
+ colormap.
+
+Sun Mar 2 05:43:06 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcheckbutton.c: 'gtk_checkbutton_size_allocate' was allocating
+ too much space to its children and not leaving the check button
+ room for the focus border.
+
+ * gtknotebook.c: 'gtk_notebook_size_request' wasn't requesting
+ enough space when the notebook tabs are visible.
+
+Sat Mar 1 01:59:35 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkpreview.c: Fixed a problem with 'gtk_preview_put' when the
+ image byte order is GDK_MSB_FIRST.
+
+ * gtksignal.c:
+ * gtksignal.h: Added 'gtk_signal_connect_after' and
+ 'gtk_signal_connect_object_after' functions. These connect signal
+ handlers which will run after the class function associated with
+ the signal.
+
+ * gtkstyle.c: Fixed a stupid bug in 'gtk_style_new_from_key' that
+ was causing twice as many styles to be created as necesary.
+
+ * gtkwidget.c: 'gtk_real_widget_size_allocate' erases the widgets
+ old allocation if it has the GTK_NO_WINDOW flag set.
+
+ * gtkwidget.c: 'gtk_real_widget_unmap' now erases the widget if it
+ has the GTK_NO_WINDOW flag set.
+
+ * gtklabel.c: Removed 'gtk_label_unmap' as similar functionality
+ was added to gtk_real_widget_unmap.
+
+ * gtkbin.c: Modified 'gtk_bin_map' and 'gtk_bin_unmap' so that it
+ erases and draws the widget if it has the GTK_NO_WINDOW flag set.
+
+ * gtkframe.c: Modified 'gtk_frame_size_allocate' so that it erases
+ the old allocation.
+
+Fri Feb 28 03:27:05 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: 'gtk_window_set_title' now changes the window title
+ if the window is already realized.
+
+ * gtkentry.c: 'gtk_entry_set_text' was emitting both a
+ "delete_text" and a "changed_text" signal. Modified so that it
+ only emits a "changed_text" signal.
+
+ * gtkpreview.c: Modified to work correctly on systems with MSB
+ byte order. The colormap for TRUE and DIRECT color displays is now
+ created if the default visual is not equal to the visual we are
+ using.
+
+ * gtkstyle.c: 'gtk_style_attach' and 'gtk_style_find' weren't
+ working properly in the presence of multiple colormaps are
+ different depth visuals.
+
+ * gtkcontainer.c: Massively improved focus traversal using tab and
+ arrow keys. It now uses the layout of the widgets to determine
+ where to move the focus to.
+
+Mon Feb 24 03:24:02 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c: Set the accelerator table field for menus when
+ they are created.
+
+ * gtkmenu.c:
+ * gtkmenu.h: Added a default accelerator table field to menus so
+ that runtime modification of accelerator keys in menus can work
+ better.
+
+ * gtkrange.c: 'gtk_range_default_{h,v}motion' had faulty logic for
+ deciding what to do when the slider was at the edge of the
+ trough. They previously didn't update the adjustment value event
+ if the value wasn't what it should be when the slider was at the
+ edge of the trough.
+
+ * gtkviewport.c: 'gtk_viewport_size_allocate' and
+ 'gtk_viewport_adjustment_value_changed' both had the potential for
+ performing a divide by 0. Checks are now in place to prevent this.
+
+ * gtkmenu.c: 'gtk_menu_map' now makes sure the menu lies on screen
+ if the position function is NULL.
+
+ * gtkentry.c: Modified selection handling. 'gtk_delete_selection'
+ actually removes the X selection now. 'gtk_entry_destroy' removes
+ the selection as well and relies on the change in "gdk.c" to make
+ sure the selection event will not be sent to a non-existant
+ window.
+
+ * gdk.c: Selection events are only passed on if the selection
+ owner is not NULL.
+
+ * gtkstyle.c: 'gtk_style_detach' and 'gtk_style_destroy' were not
+ destroying the black and white gc's.
+
+Sun Feb 23 19:17:56 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: 'gtk_window_size_request' was setting the window
+ hints. This was also being done in 'gtk_window_map', so the
+ instance being done in 'gtk_window_size_request' was removed.
+
+Fri Feb 21 01:04:01 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c: 'gtk_widget_draw' has to use the widgets allocated
+ position for the drawing rectangle when the widget has the
+ GTK_NO_WINDOW flag set.
+
+ * gtkwidget.c: In 'gtk_widget_init' the visual and colormap were
+ being directly compared against 'default_visual' and
+ 'default_colormap' instead of calling
+ 'gtk_widget_get_default_{visual,colormap}'.
+
+ * gdkrectangle.c: Amazing! There was a bug in the
+ 'gtk_rectangle_intersect' logic. Its been there for near eternity
+ and I never noticed.
+
+ * gtkpreview.c:
+ * gtkpreview.h: Created preview widget which allows drawing to an
+ rgb or grayscale buffer which is automatically displayed on the
+ screen. Performs dithering as necessary.
+
+Thu Feb 20 20:33:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkwindow.c: Modified the logic in 'gdk_window_new' which
+ determined when to add a window to the WM_COLORMAP_WINDOWS
+ property.
+
+Wed Feb 19 19:55:29 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkruler.c: 'gtk_ruler_make_pixmap' was always destroying the
+ old backing store and creating a new one even when it would create
+ a new one of exactly the same size as the old one.
+
+Tue Feb 18 18:32:10 1997 Peter Mattis <pmattis@localhost>
+
+ * gmem.c: 'g_mem_chunk_alloc' was incorrectly modifying the mem
+ areas free mem field when reallocating a previously freed
+ atom. This caused a fairly severe memory leak.
+
+ * gtkmenushell.c: 'gtk_menu_shell_button_release' had a bug in the
+ logic for deciding whether to initiate an X pointer grab or not
+ when the mouse button was released. It now only initiates a grab
+ if the mouse is released within an active menu item.
+
+Fri Feb 14 00:57:40 1997 Peter Mattis <pmattis@localhost>
+
+ * gtknotebook.c: Changed the look of notebook tabs slightly.
+
+ * gtkentry.c:
+ * gtkentry.h: Deleting an entry widget which is holding the X
+ selection presents some difficulties. The X selection must be
+ released, but the widget can't be destroyed until the
+ SELECTION_CLEAR event is received that the X server will send in
+ response to clearing the X selection. There are probably still
+ bugs in the current method of entry widget deletion when the X
+ selection is held.
+
+ * gtkmain.c: 'gtk_propagate_event' was not properly destroying the
+ toplevel window when receiving a key press event.
+
+ * gtkwidget.c: Setting a widget insensitive did not cause it to
+ redraw. It now does.
+
+Thu Feb 13 16:59:07 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkviewport.c: 'gtk_viewport_size_allocate' was allocating its
+ child widget an adjusted allocation. Since the actual scrolling
+ has handled by a subwindow this caused the child to be double
+ scrolled. Modified to always set the child allocations origin to
+ (0, 0).
+
+Wed Feb 12 01:06:48 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkentry.c: Text is now centered vertically. Previously it was
+ pushed up against the top. This problem was only evident when the
+ widget was allocated more vertical space than it requested.
+
+ * gtkfilesel.c: 'gtk_file_selection_key_press' was previously only
+ a stub for tab completion. The actual tab completion call had been
+ left out. (Oops!)
+
+Tue Feb 11 01:43:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtksignal.c: 'gtk_signal_disconnect_by_data' was going into a
+ loop and crashing. Bad logic. Fixed.
+
+ * gtkmain.c: An idle function which returns FALSE will be removed
+ from the list of idle functions. This makes the functioning of
+ idle functions and timeouts more similar.
+
+ * gtkentry.c: 'gtk_entry_get_text' now returns an empty string
+ when the actual text is NULL. This allows "stupid" programs to use
+ the value returned by 'gtk_entry_get_text' blindly (without
+ checking to see if its NULL).
+
+ * gtkradiobutton.c: Modified 'gtk_radio_button_clicked' so that
+ 'gtk_toggle_button_toggled' is called _after_ the widget state is
+ changed.
+
+ * gtksignal.c:
+ * gtksignal.h: Added 'gtk_signal_name' which returns the character
+ string name for a given signal number.
+
+ * gtkwidget.c: 'gtk_widget_set_parent' checks to see if the widget
+ is now "anchored" through the parent chain to a widget which is
+ GTK_ANCHORED. If it is, then it changes the widgets style using
+ 'gtk_rc_get_style' and recursively performs the same operation on
+ the widgets children. This is necessary is 'gtk_rc_get_style' only
+ works properly on "anchored" widgets.
+
+ * gtkwindow.c: Modified GTK_WIN_POS logic so that it is only used
+ immediately after the window has been shown.
+
+ * gtkmenu.c: 'gtk_menu_key_press'. Can now change menu item
+ accelerator keys on the fly. Why? Why not. Cool/useless feature of
+ the day.
+
+ * gtkmenuitem.c: Accelerator key drawing. Somehow that never got
+ finished. (Oops!)
+
+ * gtkdrawingarea.c: 'gtk_drawing_area_size_allocate' was not
+ actually installed during 'gtk_drawing_area_class_init'. (Oops!)
+
+ * gtkframe.c: 'gtk_frame_size_request' fixed size requisition
+ problem caused by unsigned arithmetic.
+
+ * gtkwindow.c: Modified window widget so that it only uses the
+ widget uposition auxiliary information immediately after it has
+ been shown. This prevents the annoying bug which can cause a
+ uposition'ed window to jump back to its original position after
+ the user moves it.
+
+ * gtkwidget.c: Need to ref and unref style in
+ 'gtk_widget_{push,pop}_style' to make sure that a style on the
+ style stack is not destroyed.
+
+ * gtktogglebutton.c: 'gtk_toggle_button_set_state' now calls
+ gtk_button_clicked to actually change the state of the
+ button. In this way, radio buttons can now perform the appropriate
+ actions when the toggle button state is set.
+
+Mon Feb 10 00:27:39 1997 Peter Mattis <pmattis@localhost>
+
+ * gtklist.c: 'gtk_list_select_item' and 'gtk_list_unselect_item'
+ were casting a GList* variable to a a GtkWidget* variable. Bad bad
+ bad. (Tim Janik).
+
+ * gtksignal.c: Modified 'gtk_signal_connect' and
+ 'gtk_signal_connect_object' to warn when a signal type cannot be
+ found.
+
+Sun Feb 9 00:15:30 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkoptionmenu.c:
+ * gtkoptionmenu.h: Changed option menus back to being derived from
+ buttons. This fixes up some screwiness with their user
+ interaction.
+
+ * gtkwindow.c: Modified key press handler to support focus
+ traversal.
+
+ * gtkcontainer.c:
+ * gtkcontainer.h: Added default focus traversal back in.
+
+Sat Feb 8 10:44:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkviewport.h:
+ * gtkviewport.c: Massively sped up viewport scrolling. Used to be
+ reallocating child's size (offset) each time a scrollbar
+ moved. Now a subwindow is moved. All the children are moved
+ automatically by moving the subwindow. Much much much faster.
+
+Tue Feb 4 00:20:44 1997 Peter Mattis <pmattis@localhost>
+
+ * gtree.c: Changed 'g_tree_node_search' to use a loop instead of
+ recursion.
+
+Mon Feb 3 11:30:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkbutton.c: Removed 'parent_destroy' global and replaced it
+ with 'parent_class' global to reflect style used in other
+ widgets.
+
+ * gtknotebook.c: Tab labels were being allocated less than their
+ requested size.
+
+ * gtkrange.c:
+ * gtkrange.h: Moved the "digits" field of scales into the range
+ type. The adjustment value for scales is truncated to the number
+ of visible digits instead of being left untouched.
+
+ * gtree.c: Fixed a bug in the AVL tree implementation. Single
+ rotations were always being performed during insertion. It is
+ sometimes necessary to perform a double rotation.
+
+ * gtklabel.c: Modified 'gtk_label_expose' to only draw the label
+ when the allocated space is greater than or equal to the requested
+ space.
+
+ * gtklabel.c: Added call to 'gtk_widget_unmap' to
+ 'gtk_label_destroy' in order for the label to redraw correctly
+ (erase itself) when destroyed.
+
+ * gtklabel.c: Added 'gtk_label_unmap' call which erases the labels
+ allocation when it gets unmapped.
+
+ * *.h: Removed a few remaining instances of using "class" as a
+ parameter name. (Causes problems for C++).
+
+Fri Jan 31 12:26:50 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcontainer.c: 'gtk_container_enable_resize' needs to call
+ 'gtk_container_check_resize' instead of
+ 'gtk_container_need_resize'.
+
+ * gtkwidget.c: 'gtk_real_widget_show' now maps the widget if its
+ parent is mapped.
+
+ * gtkscrolledwindow.c: Fixed size allocation when the scrollbar
+ policy's are GTK_POLICY_AUTOMATIC. Doing it correctly is harder
+ than I originally thought.
+
+ * gtklist.c: Added 'gtk_list_child_position' to determine the
+ integer position in a list of a child. Filled in the
+ 'gtk_list_item_select' and 'gtk_list_item_unselect' stubs.
+
+Thu Jan 30 16:08:06 1997 Peter Mattis <pmattis@localhost>
+
+ * gmem.c: Changed the implementation of G_ALLOC_AND_FREE mem
+ chunks. They used to allocate SIZEOF_VOID_P extra bytes per atom
+ in order to keep track of which mem area they were allocated
+ from. Now the mem area is determined by searching through an AVL
+ tree of the mem areas for a mem chunk and comparing memory
+ locations. A little slower, but makes G_ALLOC_AND_FREE mem chunks
+ much more attractive.
+
+ * gtree.c: Added an AVL tree implementation to glib.
+
+ * gtksignal.c:
+ * gstring.c: va_arg (arg_list, {char, short}) is
+ invalid. Arguments passed in a variable argument list are
+ promoted. ({char, short}->int). Seemed to work ok before under
+ Linux. Crashed under FreeBSD.
+
+Tue Jan 28 02:27:51 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkwindow.c: Fixed a major slowdown apparent in the file
+ selection dialog which was caused by calling
+ 'gtk_window_add_colormap_windows' way way way too often.
+
+ * *.c: Many widgets called 'gtk_container_need_resize' when
+ something internal changed which would cause the widget to grow or
+ shrink. The assumption was made that the widget would change size
+ and an expose event would be generated. This happens "most" of the
+ time. But its possible for certain widgets to change size without
+ generating expose events, or for its internal geometry to change
+ without a change of size which would mean no expose event was
+ generated. So a wrapper function called
+ 'gtk_container_check_resize' was created and
+ 'gtk_container_need_resize' was modified so that it returns FALSE
+ if a resize was actually generated and TRUE if nothing
+ changed. This allows 'gtk_container_check_resize' to initiate a
+ 'gtk_widget_size_allocate' and 'gtk_widget_draw' to emulate the
+ expose event.
+
+Sat Jan 25 14:17:44 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmain.c: Fixed a bug with propogating key press events. The
+ events were sent 2 times to the toplevel windows which caused the
+ focus widget to be activated twice when the space bar was pressed.
+
+ * */configure.in:
+ * */Makefile.am: Added support for libtool and removed the old
+ shared library configuration craziness.
+
+Fri Jan 24 12:59:22 1997 Peter Mattis <pmattis@localhost>
+
+ * gtktext.c:
+ * gtktext.h: Josh's fixes and additions to the text widget.
+
+ * gtkfill.c:
+ * gtkfill.h: Filler widget useful for filling space in a
+ table. Can specify a minimum size. Used by the canvas widget.
+
+ * gtknotebook.c:
+ * gtknotebook.h: Made outline of notebook widget.
+
+ * gtkcanvas.c:
+ * gtkcanvas.h: Started canvas widget. A composite of 2 rulers (w/
+ an origin), 2 scrolllbars. Guides, grids, snap to.
+
+Sun Jan 19 18:26:45 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkdialog.c:
+ * gtkdialog.h: Created dialog widget which creates a standard
+ looking dialog with buttons along the button and a separator.
+
+ * gtkxid.c: Generalized the window table code for looking up a gdk
+ window based on an XID to work for any XID and a piece of
+ data. Can now look up gdk fonts based on their XID.
+
+ * gtkruler.c:
+ * gtkruler.h:
+ * gtkhruler.c:
+ * gtkhruler.h:
+ * gtkvruler.c:
+ * gtkvruler.h: Started conversion of the ruler widget.
+
+ * gtktext.c:
+ * gtktext.h: Started conversion of the text widget. Scrolling
+ doesn't work.
+
+ * gtkmain.c: Fixed a fairly major bug. The event widget needs to
+ be in a call for the entire duration of handling an event. Not
+ just for when the event widget itself is handling the event.
+
+ * gtkfilesel.c: Fixed up some bugs with resizing.
+
+Fri Jan 10 14:18:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c:
+ * gtkwidget.h:
+ * gtkentry.c:
+ * gtkentry.h: Support for selections.
+
+ * gdkselection.c:
+ * gdk.c:
+ * gdktypes.h:
+ * gdk.h: Gdk support for X selections. Currently only text
+ selections are supported.
+
+ * gtksignal.c: Fixed a major bug which occurred when destroying an
+ object. Memory was being written to after it was freed.
+
+ * gtkfilesel.c:
+ * gtkfilesel.h: Hooked up more functionality to the file selection
+ dialog.
+
+Wed Jan 8 18:13:53 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkfilesel.c:
+ * gtkfilesel.h: Mostly converted old file selection dialog
+ widget. The widget is derived from the GtkWindow class and is
+ quite a bit simpler in the widget code.
+
+ * gtkwidget.c: Fixed 'gtk_widget_grab_focus' and
+ 'gtk_widget_grab_default' to check that the toplevel widget is a
+ type of window (which includes classes derived from windows).
+
+Tue Jan 7 01:12:32 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: Was calling 'gtk_window_resize' twice in a
+ row...why?
+
+ * gtksignal.c:
+ * gtksignal.h:
+ * *.c: Changed 'gtk_signal_new' so that the class function that is
+ called when the signal is emitted can be called either before,
+ after or both before and after the calling of any signal
+ handlers.
+
+ * gtkobject.c:
+ * gtkobject.h: Added 'object_data' mechanism for storing data
+ associated with a character string key in objects. Removed
+ 'user_data' field of objects and changed
+ 'gtk_object_{get,set}_user_data' to use the object data
+ mechanism. Removed 'handlers' field of objects.
+
+ * gtkwidget.c:
+ * gtkwidget.h:
+ * gtkwindow.c: Modified aux info mechanism to use object data
+ mechanism.
+
+ * gtksignal.c: Modified signal mechanism to use object data
+ mechanism instead of 'handlers' field.
+
+
+Mon Jan 6 15:10:16 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c: Fixed up button press handling so as to conform
+ more closely to that used by Motif.
+
+Wed Jan 1 21:27:17 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenu.c:
+ * gtkmenu.h:
+ * gtkmenubar.c:
+ * gtkmenubar.h:
+ * gtkmenushell.c:
+ * gtkmenushell.h: Reorganization of menu-ing code so that code
+ duplication is reduced. The menu shell now contains most of the
+ code for menu-ing interaction while menus and menubars simply layout
+ their child menu items in the appropriate place.
+
+Sun Dec 29 17:48:18 1996 Peter Mattis <pmattis@localhost>
+
+ * gtkmenu.c:
+ * gtkmenubar.c:
+ * gtkmenuitem.h:
+ * gtkmenuitem.c: Modifications so that menu item accelerators and
+ the submenu indicator are drawn correctly and the correct amount
+ of space is allocated.
+
+Sat Dec 28 00:32:13 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkmenufactory.h:
+ * gtkmenufactory.c: Started menu factories as an easy method to
+ create and manipulate menus.
+
+Fri Dec 27 13:17:34 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkmenu.c:
+ * gtkmenu.h:
+ * gtkmenubar.c:
+ * gtkmenubar.h:
+ * gtkmenuitem.c:
+ * gtkmenuitem.h:
+ * gtkmenushell.c:
+ * gtkmenushell.h: Implemented basic menu functionality. Menubars
+ and popup menus work. Submenus work. (Much left to be done).
+
+Wed Dec 18 15:27:05 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtktypeutils.h:
+ * gtktypeutils.c: Added 'gtk_type_from_name' which returns a type
+ identifier given a type name. Implemented using a second hash
+ table keyed by type names.
+
+ * gtkbutton.c:
+ * gtktogglebutton.c: Fixed very small messed-up drawing bug when a
+ button loses its focus.
+
+ * gtkwidget.h:
+ * gtkwidget.c:
+ * gtkbutton.c:
+ * gtkwindow.c: Added default button handling. Default buttons now
+ draw correctly and pressing return or enter causes the default
+ button (if one exists) to be activated.
+
+Tue Dec 17 19:32:21 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkhscale.c:
+ * gtkvscale.c: Overrode 'draw_slider' method of ranges in order to
+ draw the slider of scales with a line in them so as to be closer
+ to the Motif look-and-feel.
+
+ * gtkwindow.c: Modified 'gtk_window_focus_in_event' so that focus
+ in events are only handled when the window is visible. Fixes a bug
+ where spurious focus in events get sent when a window is being
+ hidden.
+
+ * gtkwidget.h: Added 'activate_signal' field to the GtkWidgetClass
+ structure. Added 'gtk_widget_activate' call to emit the activate
+ signal for a widget if it is non-zero.
+
+Tue Dec 10 15:59:45 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkwidget.c: 'gtk_widget_set_name' oops in strdup'ing the old
+ "widget->name" instead of the new one we are setting.
+
+ * gtkrc.c: 'gtk_rc_widget_path' changed to use
+ 'gtk_widget_get_name' instead of accessing the "widget->name"
+ field directly.
+
+ * gtkwidget.c: Added 'gtk_widget_get_name' function which returns
+ the widgets name if it exists and the widgets type name if it does
+ not.
+
+ * gtkcheckbutton.c: Added 'gtk_check_button_draw'
+ function. Modified 'gtk_check_button_expose' to pass an expose
+ event to child instead of callings its draw function.
+
+ * gtkentry.c: 'gtk_entry_draw_text' why was "+1" being added to
+ the font->ascent to calculate the font position? This was wrong
+ and caused some characters in fonts to be clipped. (Notably "g").
+
+ * gtkentry.c: 'gtk_entry_realize' specify GTK_BUTTON1_MOTION_MASK
+ and GTK_POINTER_MOTION_HINT_MASK for _both_ windows.
+
+ * gtkmain.c: 'gtk_propagate_event' needs to set the GTK_IN_CALL
+ flag for the object before calling 'gtk_widget_event' and needs to
+ destroy the object if necessary after 'gtk_widget_event' returns.
+
+ * gtkradiobutton.c: 'gtk_radio_button_clicked' needs to call
+ 'gtk_toggle_button_toggled' when the currently active button is
+ toggled.
+
+ * gtkwidget.c: 'gtk_real_widget_hide' needs to call
+ 'gtk_widget_unmap' if the widget is currently mapped.
+
+ * gtkwindow.c: Prevent automatic resizing after the user has
+ specified a new window size. Add 'handling_resize' flag to
+ windows.
+
+ * gtkscrolledwindow.c: Implement the GTK_POLICY_AUTOMATIC
+ scrollbar policy. Need to connect to the adjustments 'changed'
+ signal and notice when the scrollbars aren't in use.
+
+ * gtkcontainer.c: 'gtk_container_init' must set 'auto_resize' and
+ 'need_resize' fields to TRUE and FALSE respectively.
+
+ * gtkwidget.c: 'gtk_widget_set_parent' must all set a widgets state
+ to its parents state.
+
+Sun Dec 1 01:31:01 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * Started ChangeLog

+ to fix some viewport bugs
+
+Mon Nov 17 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtkwidget.c: gtk-ajaborsk-971016-2
+ A little patch again to prevent user to use gtk_widget_set_events()
+ when a widget is already realized.
+ In this case, the gtk_widget_set_events() doesn't work.
+
+Mon Nov 17 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtkwindow.c: gtk-ajaborsk-971016-1
+ This small patch correct position for GTK_WIN_POS_CENTER and
+ GTK_WIN_POS_MOUSE GtkWindow positions.
+
+Sat Nov 15 1997 Jay Painter <jpaint@serv.net>
+ * gdk/gdkgc.c: added function gdk_gc_set_clip_rectangle
+ * gdk/gdk.h: header for above
+

+ * gdk/gdkgc.c: added function gdk_gc_set_clip_rectangle
+ * gdk/gdk.h: header for above
+
+Wed Nov 12 1997 Jay Painter <jpaint@serv.net>
+ * gdk/gdkpixmap.c: Patrice Fortier's patch for transparent pixmaps.
+ * gdk/gdk.h:
+ gdk/gdkdraw.c: Patrice Fortier's patch to add pixel draw function.
+
+Sun Nov 9 1997 Jay Painter <jpaint@serv.net>
+ * Fixed problems with makefiles relating to the bug
+ which required glib to be installed.
+ * Fixed makefiles to incluce the xpm's in gtk+/gtk needed
+ for testgtk.
+ * Updated gtk+ and gtk+/glib to libtool-1.0f
+
+Fri Nov 7 1997 Jay Painter <jpaint@serv.net>
+ * gtk/gtktext.c: return char_widths[ch & 0xff]; in line 2152
+
+Thr Nov 5 1997 Jay Painter <jpaint@serv.net>
+ * gtk/testgtk.c: added drag and drop test, removed the test hack
+ from the button test
+
+Tue Nov 4 08:28:57 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gtk/gtkmain.c (gtk_handle_idle): Patch from David Mosberger to
+ avoid crashes when handling idle function (this manifested itself
+ in the Umax and Microtek backends in SANE.
+
+Sun Nov 2 07:34:56 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtkfilesel.c: Small fixes about a segmentation viaolation
+ cause by a double click in the directoy list (introduced by my
+ previous changes).
+
+ * gtk/gtklist.c: Small fixes to gtk_list_add() and gtk_list_remove().
+
+ * gtk/testgtk.c (list_add): Applied Stefan Wille's patch to make this
+ function do something ;).
+
+Fri Oct 31 Jay Painter <jpaint@serv.net>
+ *gdk/gdk.c: reformatted DND code for GTK coding standards
+ *gdk/gdkwindow.c: changed memory allocation for DND to q_mem stuff
+
+Thu Oct 30 Jay Painter <jpaint@serv.net>
+ * gdk/gdkwindow.c:
+ * gdk/gdk/gdk.h:
+ * gtk/gtkwidget.h:
+ * gtk/gtkwidget.c: Applied Stephan Willie's shaped window patch
+
+ * gdk/gdkwindow:
+ * gdk/gdk.h:
+ * gtk/gtkwidget.h:
+ * gtk/gtkwidget.c: reformatted the DND code to conform to GTK
+ coding standards
+
+ * gtk/testgtk: massive fixes, SW's shaped window example
+
+Thu Oct 30 07:33:27 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtklistitem.c (gtk_real_list_item_toggle): applied Johannes
+ Keukelaar's <johannes@nada.kth.se> patch for keyboard support in
+ GtkList widgets.
+
+ * gtk/gtkfilesel.c: adapted dir and file list selection
+ behaviour to deal with keyboard selections. this is a little
+ bit tricky: in the dir list it just changes the entrys value on a one
+ button press. but on a keyboard selection via gtk_widget_activate() it
+ does a new population (likewise on a double click) as this seems more
+ obvious.
+
+1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
+
+ * gdk/gdkcolor.c (gdk_colormap_get_system): Initialize
+ private->ref_count.
+
+Wed Oct 22 09:47:43 1997 Tim Janik <timj@psynet.net>
+
+ * gtk/gtkwindow.c (gtk_window_key_release_event): Fixed a stupid
+ bug that caused the key_release_event to be propagated twice.
+
+Sun Oct 12 11:01:43 1997 Tim Janik <timj@psynet.net>
+
+ * acconfig.h:
+ * configure.in:
+ * gdk/gdkimage.c: Added configure check for IPC_RMID_DEFERRED_RELEASE,
+ because shmat() fails after a shmctl(..., IPC_RMID,...) for OSF1 V3.2,
+ SunOS 4.1.1, 5.5, 5.5.1, 5.6, IRIX 5.2 and 6.2.
+
+Mon Oct 6 11:59:07 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gdk/gdk.c (gdk_event_translate): In line 1693, fixed typo that
+ would cause motion notify events not to be delivered.
+
+Sun Oct 5 18:15:06 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gtk/gtkrc.c (gtk_rc_parse_bg_pixmap): Changed strdup() for
+ g_strdup().
+
+Wed Sep 24 17:16:34 1997 Peter Mattis <pmattis@bjork.inktomi.com>
+
+ * configure.in: Fixed a stupid error in the test for libXext that
+ would cause it to fail if X_EXTRA_LIBS was not empty.
+
+ * gtk/gtkmain.h (gtk-timj-970919.patch):
+ * gtk/gtkmain.c (gtk-timj-970919.patch): new function
+ `gtk_idle_remove_by_data' to remove all idle callbacks that take a
+ specific piece of data as argument. (gtk_get_current_event):
+ remove idles through gtk_idle_remove_by_data.
+
+ * gtk/gtkwidget.c (gtk-timj-970919.patch):
+ (gtk_widget_destroy): remove pending idles for
+ widgets that have GTK_REDRAW_PENDING or GTK_RESIZE_PENDING and
+ GTK_ANCHORED set (only anchored widgets can have a resize queue
+ handler pending). widgets that have GTK_RESIZE_NEEDED will be removed
+ from their anchored toplevels `resize_widgets' list.
+
+ (gtk_widget_queue_draw): let the widget remember the queue handler
+ tag (through `redraw_handler_key') for later call to `gtk_idle_remove'.
+
+ (gtk_widget_queue_resize): let the widget remember the queue handler
+ tag (through `resize_handler_key') for later call to `gtk_idle_remove'.
+ corrected referencing the toplevel widget for which the handler is
+ pending. if a widget is added to the `resize_widgets' list of a
+ toplevel widget, GTK_RESIZE_NEEDED is set and it's referenced.
+
+ (gtk_real_widget_queue_resize): on the deletion of the `resize_widgets'
+ list, unset GTK_RESIZE_NEEDED and unreference the removed widgets.
+
+ * gtk/gtkwindow.c (gtk-timj-970919.patch):
+ (gtk_real_window_move_resize): move `resize_containers = NULL'
+ initialization out of if-statement.
+ while stepping through the `resize_widgets' list, unreference the
+ widgets and clear GTK_RESIZE_NEEDED. if a widget realy needs are
+ resize, they are flagged through GTK_RESIZE_NEEDED now (instead of
+ GTK_RESIZE_PENDING, as this is indicative for a pending handler).
+ added checks to provide segfaulting if a widgets parent pointer
+ is NULL (e.g. on toplevel widgets that have GTK_RESIZE_NEEDED set).
+
+Tue Sep 23 13:23:27 1997 Federico Mena <federico@bananoid.nuclecu.unam.mx>
+
+ * gdk/gdkimage.c: Applied Tim Janik's patch to mark shm segments
+ as IPC_RMID so that they are automatically removed always.
+
+ * gdk/gdkfont.c: Removed casts from lvalues.
+
+ * gtk/gtkmain.c: Removed GTK_RETLOC_*() (which do a cast) from lvalues.
+
+ * gtk/gtkaccelerator.c (gtk_accelerator_table_remove): Added
+ "const" to the accelerator_key param to be consistent with the
+ declaration in gtkaccelerator.h. The const is not useful in this
+ case, anyway.
+
+Tue Sep 16 13:11:06 1997 Peter Mattis <pmattis@bjork.inktomi.com>
+
+ * gtkpreview.c: Andrew Logan Kieschnick's change to eliminate
+ round-off error when gamma is set to 1.0.
+
+ * gtkrange.c:
+ * gtkviewport.c: Jay Painter's changes to modify the way in which
+ viewports resize.
+
+ * gdkinput.c:
+ * gdkinputgxi.h:
+ * gdkinputxfree.h:
+ * gtk/Makefile.am:
+ * gtk.h:
+ * gtkeventbox.c:
+ * gtkeventbox.h: Owen Taylor's event box widget and fixes for X
+ input support (that I had broken).
+
+ * gdk.h:
+ * gdkwindow.c:
+ * gtksignal.h:
+ * gtksignal.c: Elliot Lee's changes to support Objective C. (id is
+ apparently a reserved word in Objective C).
+
+Sun Sep 14 22:33:15 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c (gtk_widget_queue_resize): If the toplevel container
+ is invisible we simply call "gtk_container_need_resize" on
+ it. This fixes a bug with option menus not redrawing correctly.
+
+ * gtkmenuitem.c (gtk_menu_item_enter): (gtk_menu_item_leave):
+ These functions now simply pass the event on to their parent. This
+ is necessary for menus to work properly due to the change in how
+ grabs are dealts with.
+
+ * gtkwindow.c (gtk_real_window_move_resize): Fixed a bug that
+ caused the GTK_RESIZE_PENDING flag to not be unset in some cases.
+
+Fri Sep 5 20:49:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
+
+ Bug fixes:
+
+ * Makefile.am: Added PATCHES to EXTRA_DIST.
+ * gtk/gtkpixmap.c (gtk_pixmap_new): Move the "pixmap != NULL" test
+ after the allocation of the pixmap.
+
+ To shut up the compiler:
+
+ * gtk/gtkfilesel.c (get_pwdb): Initialize home_dir.
+ * gtk/gtkmain.c (gtk_init): Replace comments around calls to
+ g_set_*_handler with "if (0)".
+ * gtk/gtkrc.c (gtk_rc_get_token): Initialize hex_number and
+ float_number.
+ * gtk/gtkwindow.c (gtk_window_key_press_event): Initialize
+ direction.
+
+ Changes to the type system in gtk/:
+
+ * Makefile.am: Added gtktypebuiltins.h to gtkinclude_HEADERS.
+ Added gtk.defs, runelisp, gentypeinfo.el and gtktypebuiltins.c to
+ EXTRA_DIST. Added rules to generate gtktypebuiltins.* from
+ gtk.defs.
+
+ * runelisp, gentypeinfo.el, gtk.defs: New files.
+
+ * gtkaccelerator.c, gtkaccelerator.h (gtk_accelerator_table_ref):
+ Return the table so that this function can be used as the `copy'
+ function for GTK_TYPE_BOXED values.
+ * gtkstyle.c, gtkstyle.h (gtk_style_ref): Likewise.
+
+ * gtkenums.h: Removed GtkArgType enum.
+
+ * gtkmain.c (gtk_init): Call gtk_type_init to initialize the type
+ system.
+
+ * gtkobject.c (gtk_object_init_type): New function to take over
+ for gtk_object_get_type. (gtk_object_get_type): Just return the
+ constant GTK_TYPE_OBJECT. (gtk_object_collect_args): Do the right
+ thing for the new GTK_TYPE_* types.
+ * gtksignal.c (gtk_params_get): Likewise.
+
+ * gtktypeutils.c: (gtk_type_init_builtin_types): New
+ function. (gtk_type_init): Call it. Also made non-static.
+ (gtk_type_unique): The allocation scheme for numerical ids has
+ changed: The low 8 bits hold the appropriate GtkFundamentalType of
+ a type, the rest is a globally unique sequence number.
+ (gtk_type_hash): Use the sequence number of a key to hash it.
+ (gtk_type_register_builtin): New function.
+
+ * gtktypeutils.h: (GtkFundamentalType): New enumeration of the
+ fundamental types. (GTK_TYPE_MAKE, GTK_FUNDAMENTAL_TYPE,
+ GTK_TYPE_SEQNO): New macros to work with the new id scheme.
+ (GtkArg): Added fields for new types and renamed old ones. GtkArg
+ should now be a mostly opaque structure, except name and type.
+ (GTK_VALUE_*): New macros to access the values of a GtkArg.
+ (GTK_RETLOC_*): New macros to access the location of a return
+ value that is contained in a GtkArg. * gtktypebuiltins.h: New
+ file to access the typeids of the builtin types.
+
+ * gtkwidget.h (GTK_TYPE_WIDGET): New macro to access the type id
+ of the widget class.
+
+ Thru out: Changed GTK_ARG_* to the appropriate GTK_TYPE_*.
+ Changed access to GtkArg structure to the appropriate GTK_VALUE_*
+ or GTK_RETLOC_* macro. Changed GtkArgType to GtkType. Changed
+ some guints to GtkType.
+
+ General changes in gtk/ to support interpreters:
+
+ * gtkradiobutton.c (gtk_radio_button_new_from_widget,
+ gtk_radio_button_new_with_label_from_widget): New functions.
+
+ * gtksignal.c (gtk_signal_connect_no_marshal): New function.
+ (struct _GtkHandler): Added no_marshal and destroy_func fields.
+ (gtk_signal_handler_new): Initialize them.
+ (gtk_signal_connect_by_type): Added no_marshal and destroy_func
+ arguments. Changed all callers.
+ (gtk_signal_destroy): Invoke destroy_func if there is one and the
+ global destroy func does not apply. (gtk_handlers_run): If the
+ handler has no_marshal set, call its function directly without
+ going thru the signal's marshaller.
+
+Wed Sep 3 09:56:22 1997 RHS Linux User <pmattis@bjork.inktomi.com>
+
+ * gtkrange.c: Changed the way the range control focus was drawn so
+ that the range control is drawn correctly when it does not have
+ the focus.
+
+Tue Sep 2 17:41:17 1997 RHS Linux User <pmattis@bjork.inktomi.com>
+
+ * gtkwidget.c: 'gtk_real_widget_queue_resize' should only remove
+ the "resize_widgets" if another resize is not pending.
+
+Mon Sep 1 18:28:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmain.c: Changed the way GDK_DELETE events are handled. Only,
+ if 'gtk_widget_event' returns TRUE is the widget destroyed. By
+ default, 'gtk_widget_event' will return FALSE causing the window
+ to not be destroyed. This prevents segfaults in the GIMP and other
+ programs that do not correctly handle GDK_DELETE events.
+
+ * gtkmain.c: Added modal dialog support by allowing events
+ destined for a child of the grab widget to go to the child instead
+ of the grab widget. (Added 'gtk_widget_is_ancestor' to determine
+ the relationship between the grab widget and the event widget).
+
+ * *.[ch]: Incorprated a whole mess of patches. (Started keeping
+ the ChangeLog up to date again).
+
+Thu Jun 5 17:22:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c:
+ * gtkmenufactory.h: Added 'gtk_menu_factory_remove_*'
+ calls. Removing entries/paths causes the associated widgets to be
+ destroyed.
+
+ * gtkwidget.c:
+ * gtkwidget.h: Calling 'gtk_widget_set_style' is used as an
+ indication that the programmer specifically wants that style to be
+ used. RC-style substitution is disabled for the widget after such
+ a call.
+
+ * gtkpixmap.c:
+ * gtkpixmap.h:
+ * gtkimage.c:
+ * gtkimage.h: Changed to use clip mask and a single pixmap (or
+ image) to deal with transparent areas.
+
+ * gdkpixmap.c: Modified xpm loading routines to optionally return
+ a clip mask.
+
+ * gdkgc.c:
+ * gdkdraw.c:
+ * gdktypes.h: Modifications to allow clip masks to be used with
+ gc's. Clip masks are bitmaps that specify drawable regions.
+
+Thu May 1 03:11:51 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkscrolledwindow.c: Scrolled windows need to have the
+ GTK_NO_WINDOW flag set. Not having it set caused an obscure
+ redrawing bug.
+
+Wed Apr 30 12:38:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkhruler.c:
+ * gtkvruler.c: Fixed a small bug that caused the indicator to be
+ positioned slightly off.
+
+Sun Apr 27 14:28:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c:
+ * gtkmenushell.h:
+ * gtkmenu.c:
+ * gtkmenu.h: Changes so that if a menu is popped up there is a
+ timeout period during which a menu item will not be activated and
+ if the mouse button is released in that period the menu will stay
+ popped up.
+
+ * gtkcurve.c:
+ * gtkcurve.h: Included curve widget courtesy of David
+ Mosberger-Tang (davidm@azstarnet.com).
+
+ * gtkentry.c:
+ * gtkentry.h: Changed "insert" and "delete" signals to
+ "insert_text" and "delete_text" respectively. (The symbol "delete"
+ cannot be used since it is a C++ reserved word).
+
+Sat Apr 19 01:43:49 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c: A path which ends in "<nothing>" will cause an
+ invisible (hidden) menu entry to be created. This is useful for
+ setting an accelerator key for which a corresponding menu entry is
+ not desired.
+
+ * gtktooltips.c: Fixed some problems with destruction of the
+ active tip widget not properly updating the tooltips data
+ structures.
+
+Fri Apr 18 15:09:45 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcontainer.c:
+ * gtklist.c:
+ * gtkwidget.c:
+ * gtkwidget.h: Patch from Owen Taylor (owt1@cornell.edu) which
+ fixes problems with destruction of objects and with destruction of
+ objects which hold the focus.
+
+Thu Apr 17 11:29:15 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c: Incorrect logic in
+ 'gtk_menu_shell_button_release' for deciding when a menu should
+ stay popped up when the mouse button is released.
+
+ * *.c: Miscellaneous fixes from folks on the net.
+
+Tue Apr 15 02:43:17 1997 Peter Mattis <pmattis@localhost>
+
+ * *.c:
+ * gtkwidget.h: Added GTK_BASIC widget flag which when set
+ specifies a widget as "basic". A "basic" widget is one which
+ doesn't take input events. For example, labels, pixmaps, boxes,
+ tables, alignments, etc.
+
+Sat Apr 12 15:23:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcolorsel.c: Add "#include <math.h>" to define M_PI.
+
+ * gtksignal.c: Fixed a bug in 'gtk_signal_emit' which showed up
+ because of the new cast checking macros. The 'object' was being
+ accessed after it had been destroyed.
+
+ * gtkoptionmenu.c: Fixed bug with using 'GTK_BIN' instead of
+ 'GTK_BUTTON' which showed up because of the new cast checking
+ macros.
+
+ * *.h: 'GTK_CHECK_CAST', 'GTK_CHECK_CLASS_CAST' and
+ 'GTK_CHECK_TYPE' used by standard widget macros everywhere.
+
+Wed Apr 9 00:54:17 1997 Peter Mattis <pmattis@localhost>
+
+ * docs/gtk.texi: Started further work on documentation. Major
+ changes and additions are being made.
+
+ * gtkarrow.c:
+ * gtkarrow.h: Removed function 'gtk_arrow_get'.
+
+ * gtkcontainer.c: 'gtk_container_check_resize' no performs
+ additional checking to account for the case where the containers
+ allocation is no longer sufficient because its parent (or its
+ parents parent, etc.) needs to resize its children.
+
+Tue Apr 8 21:15:50 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkstyle.c: Fixed a bug in 'gtk_style_init' in which the font
+ was not ref'd (via 'gdk_font_ref'), but was free'd (via in
+ 'gdk_font_free') in 'gtk_style_destroy'. (David
+ Mosberger-Tang). Also cleaned up 'gtk_style_destroy' while I was
+ at it.
+
+ * gtkmain.c: Fixed a bug in 'gtk_propogate_event' which caused
+ entry widgets (and probably other widgets) not to be destroyed in
+ some instances.
+
+Mon Apr 7 01:20:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkentry.c:
+ * gtkentry.h: Changed the "insert_text", "delete_text" and
+ "changed_text" signals to "insert", "delete", and "changed"
+ respectively. They really should have been named this way
+ originally except the previous signal mechanism prevented
+ duplicate signal names. ("changed" is also used by adjustments).
+
+ * gtkradiomenuitem.c:
+ * gtkradiomenuitem.h: New widget.
+
+ * gtkcheckmenuitem.c:
+ * gtkcheckmenuitem.h: New widget.
+
+ * gtksignal.c: Modified 'gtk_signal_lookup' to require an object
+ type to be passed as a parameter. In addition, signals are now
+ only needed to be uniquely defined in their branch of the class
+ hierarchy. This allows the same signal name to be used in two
+ different branches of the class hierarchy. For instance, the
+ "changed" signal is used both by adjustments and entries...in
+ different ways!
+
+ * gtktypeutils.c: Added 'gtk_type_parent' which returns the parent
+ type for a given type.
+
+Sun Apr 6 22:08:35 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c: If a widget is set insensitive it loses the focus
+ if it had it.
+
+ * gtkcontainer.c: Insensitive widgets no longer participate in tab
+ traversal.
+
+ * gtkscrolledwindow.c: The "viewport" child is now destroyed and a
+ container class "foreach" function was written (which fixes the
+ sensitivity bug).
+
+Sat Apr 5 14:25:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkhscrollbar.c:
+ * gtkvscrollbar.c: Fixed trough size allocation bug.
+
+ * gtkhscale.c:
+ * gtkvscale.c: Fixed trough size allocation and position bug that
+ showed up when scales were placed in notebooks.
+
+Thu Mar 27 17:45:54 1997 David Mosberger-Tang <davidm@azstarnet.com>
+
+ * gtk/gtkmain.c (gtk_handle_idle): Fix appending pending_idles to
+ idle_functions so it works even when idle_functions is empty.
+
+Sat Mar 15 14:15:59 1997 Peter Mattis <pmattis@localhost>
+
+ * *.[ch]: Moved '*_class_init' and '*_init' function declarations
+ for widgets into the source file as those functions no longer had
+ to be public.
+
+ * gtkcheckbutton.c: Fixed redrawing of check button.
+
+ * gtkframe.c: Fixed redrawing of frame when the shadow type is
+ changed.
+
+Sat Mar 8 15:19:23 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkimage.c: Fixed a stupid bug with 'gdk_image_new' which
+ potentially added a NULL image to "image_list" and caused problems
+ when 'gdk_image_exit' was called.
+
+Wed Mar 5 00:40:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkpreview.c: Massively changed the colormap handling used by
+ the preview widget. Gray previews are now dithered. A single
+ visual and colormap is shared by the color and gray previews. A
+ GTK_PREVIEW_INFO property is installed on the root window in
+ certain cases to allow multiple GTK programs to share the system
+ colormap.
+
+Sun Mar 2 05:43:06 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcheckbutton.c: 'gtk_checkbutton_size_allocate' was allocating
+ too much space to its children and not leaving the check button
+ room for the focus border.
+
+ * gtknotebook.c: 'gtk_notebook_size_request' wasn't requesting
+ enough space when the notebook tabs are visible.
+
+Sat Mar 1 01:59:35 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkpreview.c: Fixed a problem with 'gtk_preview_put' when the
+ image byte order is GDK_MSB_FIRST.
+
+ * gtksignal.c:
+ * gtksignal.h: Added 'gtk_signal_connect_after' and
+ 'gtk_signal_connect_object_after' functions. These connect signal
+ handlers which will run after the class function associated with
+ the signal.
+
+ * gtkstyle.c: Fixed a stupid bug in 'gtk_style_new_from_key' that
+ was causing twice as many styles to be created as necesary.
+
+ * gtkwidget.c: 'gtk_real_widget_size_allocate' erases the widgets
+ old allocation if it has the GTK_NO_WINDOW flag set.
+
+ * gtkwidget.c: 'gtk_real_widget_unmap' now erases the widget if it
+ has the GTK_NO_WINDOW flag set.
+
+ * gtklabel.c: Removed 'gtk_label_unmap' as similar functionality
+ was added to gtk_real_widget_unmap.
+
+ * gtkbin.c: Modified 'gtk_bin_map' and 'gtk_bin_unmap' so that it
+ erases and draws the widget if it has the GTK_NO_WINDOW flag set.
+
+ * gtkframe.c: Modified 'gtk_frame_size_allocate' so that it erases
+ the old allocation.
+
+Fri Feb 28 03:27:05 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: 'gtk_window_set_title' now changes the window title
+ if the window is already realized.
+
+ * gtkentry.c: 'gtk_entry_set_text' was emitting both a
+ "delete_text" and a "changed_text" signal. Modified so that it
+ only emits a "changed_text" signal.
+
+ * gtkpreview.c: Modified to work correctly on systems with MSB
+ byte order. The colormap for TRUE and DIRECT color displays is now
+ created if the default visual is not equal to the visual we are
+ using.
+
+ * gtkstyle.c: 'gtk_style_attach' and 'gtk_style_find' weren't
+ working properly in the presence of multiple colormaps are
+ different depth visuals.
+
+ * gtkcontainer.c: Massively improved focus traversal using tab and
+ arrow keys. It now uses the layout of the widgets to determine
+ where to move the focus to.
+
+Mon Feb 24 03:24:02 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenufactory.c: Set the accelerator table field for menus when
+ they are created.
+
+ * gtkmenu.c:
+ * gtkmenu.h: Added a default accelerator table field to menus so
+ that runtime modification of accelerator keys in menus can work
+ better.
+
+ * gtkrange.c: 'gtk_range_default_{h,v}motion' had faulty logic for
+ deciding what to do when the slider was at the edge of the
+ trough. They previously didn't update the adjustment value event
+ if the value wasn't what it should be when the slider was at the
+ edge of the trough.
+
+ * gtkviewport.c: 'gtk_viewport_size_allocate' and
+ 'gtk_viewport_adjustment_value_changed' both had the potential for
+ performing a divide by 0. Checks are now in place to prevent this.
+
+ * gtkmenu.c: 'gtk_menu_map' now makes sure the menu lies on screen
+ if the position function is NULL.
+
+ * gtkentry.c: Modified selection handling. 'gtk_delete_selection'
+ actually removes the X selection now. 'gtk_entry_destroy' removes
+ the selection as well and relies on the change in "gdk.c" to make
+ sure the selection event will not be sent to a non-existant
+ window.
+
+ * gdk.c: Selection events are only passed on if the selection
+ owner is not NULL.
+
+ * gtkstyle.c: 'gtk_style_detach' and 'gtk_style_destroy' were not
+ destroying the black and white gc's.
+
+Sun Feb 23 19:17:56 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: 'gtk_window_size_request' was setting the window
+ hints. This was also being done in 'gtk_window_map', so the
+ instance being done in 'gtk_window_size_request' was removed.
+
+Fri Feb 21 01:04:01 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c: 'gtk_widget_draw' has to use the widgets allocated
+ position for the drawing rectangle when the widget has the
+ GTK_NO_WINDOW flag set.
+
+ * gtkwidget.c: In 'gtk_widget_init' the visual and colormap were
+ being directly compared against 'default_visual' and
+ 'default_colormap' instead of calling
+ 'gtk_widget_get_default_{visual,colormap}'.
+
+ * gdkrectangle.c: Amazing! There was a bug in the
+ 'gtk_rectangle_intersect' logic. Its been there for near eternity
+ and I never noticed.
+
+ * gtkpreview.c:
+ * gtkpreview.h: Created preview widget which allows drawing to an
+ rgb or grayscale buffer which is automatically displayed on the
+ screen. Performs dithering as necessary.
+
+Thu Feb 20 20:33:21 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkwindow.c: Modified the logic in 'gdk_window_new' which
+ determined when to add a window to the WM_COLORMAP_WINDOWS
+ property.
+
+Wed Feb 19 19:55:29 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkruler.c: 'gtk_ruler_make_pixmap' was always destroying the
+ old backing store and creating a new one even when it would create
+ a new one of exactly the same size as the old one.
+
+Tue Feb 18 18:32:10 1997 Peter Mattis <pmattis@localhost>
+
+ * gmem.c: 'g_mem_chunk_alloc' was incorrectly modifying the mem
+ areas free mem field when reallocating a previously freed
+ atom. This caused a fairly severe memory leak.
+
+ * gtkmenushell.c: 'gtk_menu_shell_button_release' had a bug in the
+ logic for deciding whether to initiate an X pointer grab or not
+ when the mouse button was released. It now only initiates a grab
+ if the mouse is released within an active menu item.
+
+Fri Feb 14 00:57:40 1997 Peter Mattis <pmattis@localhost>
+
+ * gtknotebook.c: Changed the look of notebook tabs slightly.
+
+ * gtkentry.c:
+ * gtkentry.h: Deleting an entry widget which is holding the X
+ selection presents some difficulties. The X selection must be
+ released, but the widget can't be destroyed until the
+ SELECTION_CLEAR event is received that the X server will send in
+ response to clearing the X selection. There are probably still
+ bugs in the current method of entry widget deletion when the X
+ selection is held.
+
+ * gtkmain.c: 'gtk_propagate_event' was not properly destroying the
+ toplevel window when receiving a key press event.
+
+ * gtkwidget.c: Setting a widget insensitive did not cause it to
+ redraw. It now does.
+
+Thu Feb 13 16:59:07 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkviewport.c: 'gtk_viewport_size_allocate' was allocating its
+ child widget an adjusted allocation. Since the actual scrolling
+ has handled by a subwindow this caused the child to be double
+ scrolled. Modified to always set the child allocations origin to
+ (0, 0).
+
+Wed Feb 12 01:06:48 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkentry.c: Text is now centered vertically. Previously it was
+ pushed up against the top. This problem was only evident when the
+ widget was allocated more vertical space than it requested.
+
+ * gtkfilesel.c: 'gtk_file_selection_key_press' was previously only
+ a stub for tab completion. The actual tab completion call had been
+ left out. (Oops!)
+
+Tue Feb 11 01:43:08 1997 Peter Mattis <pmattis@localhost>
+
+ * gtksignal.c: 'gtk_signal_disconnect_by_data' was going into a
+ loop and crashing. Bad logic. Fixed.
+
+ * gtkmain.c: An idle function which returns FALSE will be removed
+ from the list of idle functions. This makes the functioning of
+ idle functions and timeouts more similar.
+
+ * gtkentry.c: 'gtk_entry_get_text' now returns an empty string
+ when the actual text is NULL. This allows "stupid" programs to use
+ the value returned by 'gtk_entry_get_text' blindly (without
+ checking to see if its NULL).
+
+ * gtkradiobutton.c: Modified 'gtk_radio_button_clicked' so that
+ 'gtk_toggle_button_toggled' is called _after_ the widget state is
+ changed.
+
+ * gtksignal.c:
+ * gtksignal.h: Added 'gtk_signal_name' which returns the character
+ string name for a given signal number.
+
+ * gtkwidget.c: 'gtk_widget_set_parent' checks to see if the widget
+ is now "anchored" through the parent chain to a widget which is
+ GTK_ANCHORED. If it is, then it changes the widgets style using
+ 'gtk_rc_get_style' and recursively performs the same operation on
+ the widgets children. This is necessary is 'gtk_rc_get_style' only
+ works properly on "anchored" widgets.
+
+ * gtkwindow.c: Modified GTK_WIN_POS logic so that it is only used
+ immediately after the window has been shown.
+
+ * gtkmenu.c: 'gtk_menu_key_press'. Can now change menu item
+ accelerator keys on the fly. Why? Why not. Cool/useless feature of
+ the day.
+
+ * gtkmenuitem.c: Accelerator key drawing. Somehow that never got
+ finished. (Oops!)
+
+ * gtkdrawingarea.c: 'gtk_drawing_area_size_allocate' was not
+ actually installed during 'gtk_drawing_area_class_init'. (Oops!)
+
+ * gtkframe.c: 'gtk_frame_size_request' fixed size requisition
+ problem caused by unsigned arithmetic.
+
+ * gtkwindow.c: Modified window widget so that it only uses the
+ widget uposition auxiliary information immediately after it has
+ been shown. This prevents the annoying bug which can cause a
+ uposition'ed window to jump back to its original position after
+ the user moves it.
+
+ * gtkwidget.c: Need to ref and unref style in
+ 'gtk_widget_{push,pop}_style' to make sure that a style on the
+ style stack is not destroyed.
+
+ * gtktogglebutton.c: 'gtk_toggle_button_set_state' now calls
+ gtk_button_clicked to actually change the state of the
+ button. In this way, radio buttons can now perform the appropriate
+ actions when the toggle button state is set.
+
+Mon Feb 10 00:27:39 1997 Peter Mattis <pmattis@localhost>
+
+ * gtklist.c: 'gtk_list_select_item' and 'gtk_list_unselect_item'
+ were casting a GList* variable to a a GtkWidget* variable. Bad bad
+ bad. (Tim Janik).
+
+ * gtksignal.c: Modified 'gtk_signal_connect' and
+ 'gtk_signal_connect_object' to warn when a signal type cannot be
+ found.
+
+Sun Feb 9 00:15:30 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkoptionmenu.c:
+ * gtkoptionmenu.h: Changed option menus back to being derived from
+ buttons. This fixes up some screwiness with their user
+ interaction.
+
+ * gtkwindow.c: Modified key press handler to support focus
+ traversal.
+
+ * gtkcontainer.c:
+ * gtkcontainer.h: Added default focus traversal back in.
+
+Sat Feb 8 10:44:38 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkviewport.h:
+ * gtkviewport.c: Massively sped up viewport scrolling. Used to be
+ reallocating child's size (offset) each time a scrollbar
+ moved. Now a subwindow is moved. All the children are moved
+ automatically by moving the subwindow. Much much much faster.
+
+Tue Feb 4 00:20:44 1997 Peter Mattis <pmattis@localhost>
+
+ * gtree.c: Changed 'g_tree_node_search' to use a loop instead of
+ recursion.
+
+Mon Feb 3 11:30:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkbutton.c: Removed 'parent_destroy' global and replaced it
+ with 'parent_class' global to reflect style used in other
+ widgets.
+
+ * gtknotebook.c: Tab labels were being allocated less than their
+ requested size.
+
+ * gtkrange.c:
+ * gtkrange.h: Moved the "digits" field of scales into the range
+ type. The adjustment value for scales is truncated to the number
+ of visible digits instead of being left untouched.
+
+ * gtree.c: Fixed a bug in the AVL tree implementation. Single
+ rotations were always being performed during insertion. It is
+ sometimes necessary to perform a double rotation.
+
+ * gtklabel.c: Modified 'gtk_label_expose' to only draw the label
+ when the allocated space is greater than or equal to the requested
+ space.
+
+ * gtklabel.c: Added call to 'gtk_widget_unmap' to
+ 'gtk_label_destroy' in order for the label to redraw correctly
+ (erase itself) when destroyed.
+
+ * gtklabel.c: Added 'gtk_label_unmap' call which erases the labels
+ allocation when it gets unmapped.
+
+ * *.h: Removed a few remaining instances of using "class" as a
+ parameter name. (Causes problems for C++).
+
+Fri Jan 31 12:26:50 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkcontainer.c: 'gtk_container_enable_resize' needs to call
+ 'gtk_container_check_resize' instead of
+ 'gtk_container_need_resize'.
+
+ * gtkwidget.c: 'gtk_real_widget_show' now maps the widget if its
+ parent is mapped.
+
+ * gtkscrolledwindow.c: Fixed size allocation when the scrollbar
+ policy's are GTK_POLICY_AUTOMATIC. Doing it correctly is harder
+ than I originally thought.
+
+ * gtklist.c: Added 'gtk_list_child_position' to determine the
+ integer position in a list of a child. Filled in the
+ 'gtk_list_item_select' and 'gtk_list_item_unselect' stubs.
+
+Thu Jan 30 16:08:06 1997 Peter Mattis <pmattis@localhost>
+
+ * gmem.c: Changed the implementation of G_ALLOC_AND_FREE mem
+ chunks. They used to allocate SIZEOF_VOID_P extra bytes per atom
+ in order to keep track of which mem area they were allocated
+ from. Now the mem area is determined by searching through an AVL
+ tree of the mem areas for a mem chunk and comparing memory
+ locations. A little slower, but makes G_ALLOC_AND_FREE mem chunks
+ much more attractive.
+
+ * gtree.c: Added an AVL tree implementation to glib.
+
+ * gtksignal.c:
+ * gstring.c: va_arg (arg_list, {char, short}) is
+ invalid. Arguments passed in a variable argument list are
+ promoted. ({char, short}->int). Seemed to work ok before under
+ Linux. Crashed under FreeBSD.
+
+Tue Jan 28 02:27:51 1997 Peter Mattis <pmattis@localhost>
+
+ * gdkwindow.c: Fixed a major slowdown apparent in the file
+ selection dialog which was caused by calling
+ 'gtk_window_add_colormap_windows' way way way too often.
+
+ * *.c: Many widgets called 'gtk_container_need_resize' when
+ something internal changed which would cause the widget to grow or
+ shrink. The assumption was made that the widget would change size
+ and an expose event would be generated. This happens "most" of the
+ time. But its possible for certain widgets to change size without
+ generating expose events, or for its internal geometry to change
+ without a change of size which would mean no expose event was
+ generated. So a wrapper function called
+ 'gtk_container_check_resize' was created and
+ 'gtk_container_need_resize' was modified so that it returns FALSE
+ if a resize was actually generated and TRUE if nothing
+ changed. This allows 'gtk_container_check_resize' to initiate a
+ 'gtk_widget_size_allocate' and 'gtk_widget_draw' to emulate the
+ expose event.
+
+Sat Jan 25 14:17:44 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmain.c: Fixed a bug with propogating key press events. The
+ events were sent 2 times to the toplevel windows which caused the
+ focus widget to be activated twice when the space bar was pressed.
+
+ * */configure.in:
+ * */Makefile.am: Added support for libtool and removed the old
+ shared library configuration craziness.
+
+Fri Jan 24 12:59:22 1997 Peter Mattis <pmattis@localhost>
+
+ * gtktext.c:
+ * gtktext.h: Josh's fixes and additions to the text widget.
+
+ * gtkfill.c:
+ * gtkfill.h: Filler widget useful for filling space in a
+ table. Can specify a minimum size. Used by the canvas widget.
+
+ * gtknotebook.c:
+ * gtknotebook.h: Made outline of notebook widget.
+
+ * gtkcanvas.c:
+ * gtkcanvas.h: Started canvas widget. A composite of 2 rulers (w/
+ an origin), 2 scrolllbars. Guides, grids, snap to.
+
+Sun Jan 19 18:26:45 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkdialog.c:
+ * gtkdialog.h: Created dialog widget which creates a standard
+ looking dialog with buttons along the button and a separator.
+
+ * gtkxid.c: Generalized the window table code for looking up a gdk
+ window based on an XID to work for any XID and a piece of
+ data. Can now look up gdk fonts based on their XID.
+
+ * gtkruler.c:
+ * gtkruler.h:
+ * gtkhruler.c:
+ * gtkhruler.h:
+ * gtkvruler.c:
+ * gtkvruler.h: Started conversion of the ruler widget.
+
+ * gtktext.c:
+ * gtktext.h: Started conversion of the text widget. Scrolling
+ doesn't work.
+
+ * gtkmain.c: Fixed a fairly major bug. The event widget needs to
+ be in a call for the entire duration of handling an event. Not
+ just for when the event widget itself is handling the event.
+
+ * gtkfilesel.c: Fixed up some bugs with resizing.
+
+Fri Jan 10 14:18:03 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwidget.c:
+ * gtkwidget.h:
+ * gtkentry.c:
+ * gtkentry.h: Support for selections.
+
+ * gdkselection.c:
+ * gdk.c:
+ * gdktypes.h:
+ * gdk.h: Gdk support for X selections. Currently only text
+ selections are supported.
+
+ * gtksignal.c: Fixed a major bug which occurred when destroying an
+ object. Memory was being written to after it was freed.
+
+ * gtkfilesel.c:
+ * gtkfilesel.h: Hooked up more functionality to the file selection
+ dialog.
+
+Wed Jan 8 18:13:53 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkfilesel.c:
+ * gtkfilesel.h: Mostly converted old file selection dialog
+ widget. The widget is derived from the GtkWindow class and is
+ quite a bit simpler in the widget code.
+
+ * gtkwidget.c: Fixed 'gtk_widget_grab_focus' and
+ 'gtk_widget_grab_default' to check that the toplevel widget is a
+ type of window (which includes classes derived from windows).
+
+Tue Jan 7 01:12:32 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkwindow.c: Was calling 'gtk_window_resize' twice in a
+ row...why?
+
+ * gtksignal.c:
+ * gtksignal.h:
+ * *.c: Changed 'gtk_signal_new' so that the class function that is
+ called when the signal is emitted can be called either before,
+ after or both before and after the calling of any signal
+ handlers.
+
+ * gtkobject.c:
+ * gtkobject.h: Added 'object_data' mechanism for storing data
+ associated with a character string key in objects. Removed
+ 'user_data' field of objects and changed
+ 'gtk_object_{get,set}_user_data' to use the object data
+ mechanism. Removed 'handlers' field of objects.
+
+ * gtkwidget.c:
+ * gtkwidget.h:
+ * gtkwindow.c: Modified aux info mechanism to use object data
+ mechanism.
+
+ * gtksignal.c: Modified signal mechanism to use object data
+ mechanism instead of 'handlers' field.
+
+
+Mon Jan 6 15:10:16 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenushell.c: Fixed up button press handling so as to conform
+ more closely to that used by Motif.
+
+Wed Jan 1 21:27:17 1997 Peter Mattis <pmattis@localhost>
+
+ * gtkmenu.c:
+ * gtkmenu.h:
+ * gtkmenubar.c:
+ * gtkmenubar.h:
+ * gtkmenushell.c:
+ * gtkmenushell.h: Reorganization of menu-ing code so that code
+ duplication is reduced. The menu shell now contains most of the
+ code for menu-ing interaction while menus and menubars simply layout
+ their child menu items in the appropriate place.
+
+Sun Dec 29 17:48:18 1996 Peter Mattis <pmattis@localhost>
+
+ * gtkmenu.c:
+ * gtkmenubar.c:
+ * gtkmenuitem.h:
+ * gtkmenuitem.c: Modifications so that menu item accelerators and
+ the submenu indicator are drawn correctly and the correct amount
+ of space is allocated.
+
+Sat Dec 28 00:32:13 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkmenufactory.h:
+ * gtkmenufactory.c: Started menu factories as an easy method to
+ create and manipulate menus.
+
+Fri Dec 27 13:17:34 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkmenu.c:
+ * gtkmenu.h:
+ * gtkmenubar.c:
+ * gtkmenubar.h:
+ * gtkmenuitem.c:
+ * gtkmenuitem.h:
+ * gtkmenushell.c:
+ * gtkmenushell.h: Implemented basic menu functionality. Menubars
+ and popup menus work. Submenus work. (Much left to be done).
+
+Wed Dec 18 15:27:05 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtktypeutils.h:
+ * gtktypeutils.c: Added 'gtk_type_from_name' which returns a type
+ identifier given a type name. Implemented using a second hash
+ table keyed by type names.
+
+ * gtkbutton.c:
+ * gtktogglebutton.c: Fixed very small messed-up drawing bug when a
+ button loses its focus.
+
+ * gtkwidget.h:
+ * gtkwidget.c:
+ * gtkbutton.c:
+ * gtkwindow.c: Added default button handling. Default buttons now
+ draw correctly and pressing return or enter causes the default
+ button (if one exists) to be activated.
+
+Tue Dec 17 19:32:21 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkhscale.c:
+ * gtkvscale.c: Overrode 'draw_slider' method of ranges in order to
+ draw the slider of scales with a line in them so as to be closer
+ to the Motif look-and-feel.
+
+ * gtkwindow.c: Modified 'gtk_window_focus_in_event' so that focus
+ in events are only handled when the window is visible. Fixes a bug
+ where spurious focus in events get sent when a window is being
+ hidden.
+
+ * gtkwidget.h: Added 'activate_signal' field to the GtkWidgetClass
+ structure. Added 'gtk_widget_activate' call to emit the activate
+ signal for a widget if it is non-zero.
+
+Tue Dec 10 15:59:45 1996 Peter Mattis <pmattis@charnley.HIP.Berkeley.EDU>
+
+ * gtkwidget.c: 'gtk_widget_set_name' oops in strdup'ing the old
+ "widget->name" instead of the new one we are setting.
+
+ * gtkrc.c: 'gtk_rc_widget_path' changed to use
+ 'gtk_widget_get_name' instead of accessing the "widget->name"
+ field directly.
+
+ * gtkwidget.c: Added 'gtk_widget_get_name' function which returns
+ the widgets name if it exists and the widgets type name if it does
+ not.
+
+ * gtkcheckbutton.c: Added 'gtk_check_button_draw'
+ function. Modified 'gtk_check_button_expose' to pass an expose
+ event to child instead of callings its draw function.
+
+ * gtkentry.c: 'gtk_entry_draw_text' why was "+1" being added to
+ the font->ascent to calculate the font position? This was wrong
+ and caused some characters in fonts to be clipped. (Notably "g").
+
+ * gtkentry.c: 'gtk_entry_realize' specify GTK_BUTTON1_MOTION_MASK
+ and GTK_POINTER_MOTION_HINT_MASK for _both_ windows.
+
+ * gtkmain.c: 'gtk_propagate_event' needs to set the GTK_IN_CALL
+ flag for the object before calling 'gtk_widget_event' and needs to
+ destroy the object if necessary after 'gtk_widget_event' returns.
+
+ * gtkradiobutton.c: 'gtk_radio_button_clicked' needs to call
+ 'gtk_toggle_button_toggled' when the currently active button is
+ toggled.
+
+ * gtkwidget.c: 'gtk_real_widget_hide' needs to call
+ 'gtk_widget_unmap' if the widget is currently mapped.
+
+ * gtkwindow.c: Prevent automatic resizing after the user has
+ specified a new window size. Add 'handling_resize' flag to
+ windows.
+
+ * gtkscrolledwindow.c: Implement the GTK_POLICY_AUTOMATIC
+ scrollbar policy. Need to connect to the adjustments 'changed'
+ signal and notice when the scrollbars aren't in use.
+
+ * gtkcontainer.c: 'gtk_container_init' must set 'auto_resize' and
+ 'need_resize' fields to TRUE and FALSE respectively.
+
+ * gtkwidget.c: 'gtk_widget_set_parent' must all set a widgets state
+ to its parents state.

+Now
+---
+
+3. Fix focus activation of list items. Does list item activation have to be
+ completely reorganized?
+
+4. Lists should scroll to center the recently selected item if it isn't
+ visible.
+
+
+The Future
+----------
+
+-Documentation
+
+-Tree widget
+
+-Text widget (needs to be finished)
+
+-Widget redrawing when the window resizes sometimes messes up.
+
+-Make sure a widget added to a list is a list item and a widget added
+ to a menu is a menu item, etc...
+
+-More dialogs? Print, font, etc?
+
+-Multiple document interface (MDI)?
+
+-Support another widget style? Should be possible using GtkStyle's, but
+ there may be some work needed to remove any style dependencies in widget
+ code. Maybe GtkStyle's should have 'draw_push_button', 'draw_check_button',
+ etc, functions to draw the various widgets.
+
+-OffiX drag and drop support
+
+-Make all widget attributes configurable after the widget is created.

+@chapter Copying
+
+GDK is @dfn{free}; this means that everyone is free to use it and free
+to redestribute it on a free basis. GDK is not in the public domain; it
+is copyrighted and there are restrictions on its distribution, but these
+restrictions are designed to permit everything that a good cooperating
+citizen would want to do. What is not allowed is to try to prevent
+others from further sharing any version of GDK that they might get from
+you.
+
+Specifically, we want to make sure that you have the right to give away
+copies of GDK, that you receive source code or else can get it if you
+want it, that you can change GDK or use pieces of it in new free
+programs, and that you know you can do these things.
+
+To make sure that everyone has such rights, we have to forbid you to
+deprive anyone else of these rights. For example, if you distribute
+copies of GDK, you must give the recipients all the rights that you
+have. You must make sure that they, too, receive or can get the source
+code. And you must tell them their rights.
+
+Also, for my own protection, we must make certain that everyone finds
+out that there is no warranty for GDK. If GDK is modified by someone
+else and passed on, we want their recipients to know that what they have
+is not what we distributed, so that any problems introduced by others
+will no reflect on our reputation.
+
+The precise conditions of the licenses for GDK are found in the General
+Public Licenses that accompanies it.

+@chapter What is GDK?
+@cindex Overview
+
+GDK is designed as a wrapper library that lies on top of Xlib. It
+performs many common and desired operations for a programmer instead
+of the programmer having to explicitly ask for such functionality from
+Xlib directly. For example, GDK provides a common interface to both
+regular and shared memory XImage types. By doing so, an application
+can nearly transparently use the fastest image type available. GDK
+also provides routines for determining the best available color depth
+and the best available visual which is not always the default visual
+for a screen.
+
+@node Initialization, Events, Overview, Top
+@comment node-name, next, previous, up
+@chapter Initialization and exit
+@cindex Initialization
+@cindex Exit
+
+Initializing GDK is easy. Simply call @code{gdk_init} passing in the
+@var{argc} and @var{argv} parameters. Exit is similarly easy. Just
+call @code{gdk_exit}.
+
+@deftypefun void gdk_init (int *@var{argc}, char ***@var{argv})
+Initializes the GDK library. The arguments @var{argc} and @var{argv}
+are scanned and any arguments that GDK recognizes are handled and
+removed. The @var{argc} and @var{argv} parameters are the values
+passed to @code{main} upon program invocation.
+@end deftypefun
+
+@deftypefun void gdk_exit (int @var{errorcode})
+Exit GDK and perform any necessary cleanup. @code{gdk_exit} will call
+the systems @code{exit} function passing @var{errorcode} as the
+parameter.
+@end deftypefun
+
+@example
+int
+main (int argc, char *argv[])
+@{
+ /* Initialize GDK. */
+ gdk_init (&argc, &argv);
+
+ /* Exit from GDK...this call will never return. */
+ gdk_exit (0);
+
+ /* Keep compiler from issuing a warning */
+ return 0;

+@node Events, Visuals, Initialization, Top
+@comment node-name, next, previous, up
+@chapter Event handling
+@cindex Events
+
+Events are the means by which GDK lets the programmer know of user
+interaction. An event is normally a button or key press or some other
+indirect user action, such as a the mouse cursor entering or leaving a
+window.
+
+There exist only a few functions for getting events and event
+information. These are @code{gdk_events_pending},
+@code{gdk_event_get}, @code{gdk_events_record} and
+@code{gdk_events_playback}. The latter two functions are useful for
+automatic testing of a software package and should normally not be
+needed in a program.
+
+@deftypefun gint gdk_events_pending (void)
+Returns the number of events pending on the event queue.
+@end deftypefun
+
+@deftypefun gint gdk_event_get (GdkEvent *@var{event})
+Return the next available event in the @var{event}
+structure. @code{gdk_event_get} will return @code{TRUE} on success and
+@code{FALSE} on failure. Success and failure is determined by whether
+an event arrived before the timeout period expired.
+@end deftypefun
+
+@deftypefun void gdk_events_record (char *@var{filename})
+Turn on recording of events. User events and certain system events will
+be saved in the file named by the variable @var{filename}. This stream
+of events can later be played back and ``should'' produce the same
+results as when the original events were handled. However, the
+programmer does need to be careful in that the state of the program must
+be the same when @code{gdk_events_record} is called and when
+@code{gdk_events_playback} is called. For this reason,
+@code{gdk_events_record} is normally not called directly, but is instead
+invoked indirectly by specifying the ``-record'' command line option.
+@end deftypefun
+
+@deftypefun void gdk_events_playback (char *@var{filename})
+Start playback of events from a file. (See the above description of
+@code{gdk_events_record}). Normally this function is not called directly
+but is invoked by the ``-playback'' command line option.
+@end deftypefun

+@chapter Copying
+
+GTK is @dfn{free}; this means that everyone is free to use it and free
+to redestribute it on a free basis. GTK is not in the public domain; it
+is copyrighted and there are restrictions on its distribution, but
+these restrictions are designed to permit everything that a good
+cooperating citizen would want to do. What is not allowed is to try to
+prevent others from further sharing any version of GTK that they might
+get from you.
+
+Specifically, we want to make sure that you have the right to give away
+copies of GTK, that you receive source code or else can get it if you
+want it, that you can change GTK or use pieces of it in new free
+programs, and that you know you can do these things.
+
+To make sure that everyone has such rights, we have to forbid you to
+deprive anyone else of these rights. For example, if you distribute
+copies of GTK, you must give the recipients all the rights that you
+have. You must make sure that they, too, receive or can get the source
+code. And you must tell them their rights.
+
+Also, for my own protection, we must make certain that everyone finds
+out that there is no warranty for GTK. If GTK is modified by someone
+else and passed on, we want their recipients to know that what they have
+is not what we distributed, so that any problems introduced by others
+will no reflect on our reputation.
+
+The precise conditions of the licenses for GTK are found in the General
+Public Licenses that accompanies it.

+@chapter What is GTK?
+@cindex Overview
+
+GTK is a library for creating graphical user interfaces similar to the
+Motif ``look and feel''. It is designed to be small and efficient, but
+still flexible enough to allow the programmer freedom in the interfaces
+created. GTK allows the programmer to use a variety of standard user
+interface widgets (@pxref{Widgets}) such as push, radio and check
+buttons, menus, lists and frames. It also provides several ``container''
+widgets which can be used to control the layout of the user interface
+elements.
+
+GTK provides some unique features. (At least, I know of no other widget
+library which provides them). For example, a button does not contain a
+label, it contains a child widget, which in most instances will be a
+label. However, the child widget can also be a pixmap, image or any
+combination possible the programmer desires. This flexibility is adhered
+to throughout the library.

+@chapter Object Overview
+@cindex Objects
+
+GTK implements a semi-simple class mechanism and an associated class
+hierarchy for widgets and several other useful objects. The GtkObject
+type is the root of the class hierarchy. It provides a few items needed
+by all classes, the foundation for the signal (@pxref{Signals})
+mechanism and the ``destroy'' method.
+
+The class hierarchy is defined by a type hierarchy. This hierarchy
+allows queries to be made in regards to a type. The basic query that can
+be performed is asking whether a given type has an ``is a'' relation
+with another type. For instance, it is common to ask whether a general
+widget pointer is a type of specific widget so that runtime sanity
+checks can be made.
+
+@section Type utility functions
+
+The @code{GtkTypeInfo} structure is used to communicate information to
+@code{gtk_type_unique} as opposed to passing in large numbers of
+parameters.
+
+@example
+typedef struct _GtkTypeInfo GtkTypeInfo;
+
+struct _GtkTypeInfo
+@{
+ gchar *type_name;
+ guint object_size;
+ guint class_size;
+ GtkClassInitFunc class_init_func;
+ GtkObjectInitFunc object_init_func;
+ GtkValueInitFunc value_init_func;
+@}
+@end example
+
+@itemize @bullet
+@item
+The @code{type_name} field refers to the name of the type. It is
+convention for the type name to be the same as the C structure type. For
+example, the type name of the @code{GtkObject} structure is
+``GtkObject''.
+
+@item
+The @code{object_size} field refers to the size in bytes of the C
+structure. The easiest (and portable) means of computing this size is by
+using the C @code{sizeof} operator. For instance, the sizeof of the
+@code{GtkObject} structure is computed by doing @code{sizeof
+(GtkObject)}.
+
+@item
+The @code{class_size} field refers to the size in bytes of the C
+structure for the class. Again, the @code{sizeof} operator should be
+used to compute this value.
+
+@item
+The @code{class_init_func} field is a callback which is used by the type
+mechanism to initialize class specific fields. The single argument this
+function takes is a pointer to a class structure.
+
+@item
+The @code{object_init_func} field is a callback which is used by the
+type mechanism to initialize object specific fields. The single argument
+this functions takes is a pointer to an object structure.
+
+@item
+The @code{value_init_func} field is a callback which is used by the type
+mechanism to initialize object stack value types. (FIXME: unfinished).
+@end itemize
+
+@deftypefun guint gtk_type_unique (guint @var{parent_type}, GtkTypeInfo *@var{type_info})
+The @var{parent_type} is simply the value of the new types parent
+type. If @var{parent_type} is 0, then the new type is the root of the
+type hierarchy. @var{type_info} is a pointer to a structure which
+contains necessary information for construction of the new
+type. Specifically, the @code{type_name}, @code{object_size} and
+@code{class_size} fields are required. The @code{class_init_func},
+@code{object_init_func} and @code{value_init_func} fields may be NULL.
+@end deftypefun
+
+@deftypefun gchar* gtk_type_name (guint @var{type})
+The returned string is the name of @var{type} as specified to
+@code{gtk_type_unique}.
+@end deftypefun
+
+@deftypefun guint gtk_type_from_name (guchar *@var{name})
+Return the type associated with @var{name}. If there is no type
+associated with @var{name}, then 0 will be returned.
+@end deftypefun
+
+@deftypefun guint gtk_type_parent (guint @var{type})
+Returns the parent type of @var{type} or 0 if @var{type} is the root of
+the type hierarchy.
+@end deftypefun
+
+@deftypefun gpointer gtk_type_class (guint @var{type})
+Returns the initialized class structure for @var{type}. The class
+structure is actually created and initialized the first time it is
+needed. If creation and initialization occurs, the @code{class_size}
+field of the @code{GtkTypeInfo} structure used to initialize this type
+is used to determine how large the class structure is. The
+@code{class_init_func} field from the @code{GtkTypeInfo} structure is
+called for all the members in the types ancestry, including the
+type. The order of this invocation proceeds from the root on down. For
+example, the @code{GtkWidgetClass} is first initialized as an
+@code{GtkObjectClass} by the object class initialization routine and
+then by the widget class initialization routine. This allows the widget
+class initialization routine to override values set by the object class
+initialization routine. The returned structure is shared by all objects
+of @var{type} and, as such, should not be modified.
+@end deftypefun
+
+@deftypefun gpointer gtk_type_new (guint @var{type})
+Returns a new instance of an @var{type} object. The object structure is
+created and initialized similarly to the class structure (as described
+above). The @code{object_size} and @code{object_init_func} fields of the
+@code{GtkTypeInfo} structure are used to determine the objects allocated
+size and the object specific initialization routine. Similarly to the
+class initialization, all the object initialization routines from the
+root on down to the particular type being created are invoked.
+@end deftypefun
+
+@deftypefun void gtk_type_describe_heritage (guint @var{type})
+Prints the type heritage for @var{type}. The heritage for a type
+includes the type and all its parent types up the type tree.
+@end deftypefun
+
+@deftypefun void gtk_type_describe_tree (guint @var{type}, gint @var{show_size})
+Prints the type tree which starts at @var{type}. @var{show_size} is a
+boolean which determines whether type sizes are printed.
+@end deftypefun
+
+@deftypefun gint gtk_type_is_a (guint @var{type}, guint @var{is_a_type})
+A predicate function which determines whether the relation @var{type}
+is_a @var{is_a_type} is true.
+@end deftypefun
+
+@section Object functions
+
+The GtkObject type is the root of the type hierarchy used by GTK. It
+provides a minimal set of fields used to implement the actual
+object, class and signal mechanisms, as well as several utility routines
+which make dealing with objects easier.
+
+For the adventurous, see @ref{Object Implementation}.
+
+@deftypefun guint gtk_object_get_type (void)
+Returns the @code{GtkObject} type identifier.
+@end deftypefun
+
+@deftypefun void gtk_object_class_add_signals (GtkObjectClass *@var{class}, gint *@var{signals}, gint @var{nsignals})
+Adds @var{signals} to the @code{signals} field in the GtkObjectClass
+structure @var{class}. @xref{Signals}.
+@end deftypefun
+
+@deftypefun void gtk_object_destroy (GtkObject *@var{object})
+Performs checks to make sure it is alright to destroy @var{object} and
+then emits the @code{destroy} signal. The check which is performed is to
+make sure @var{object} is not already processing another signal. If this
+were the case then destroying the object immediately would undoubtedly
+cause problems as the other signal would not be able to tell the object
+was destroyed. The solution is that if @var{object} is processing another
+signal we mark @var{object} is needing to be destroyed. When we finish
+processing of the other signal we check whether the object needs to be
+destroyed.
+@end deftypefun
+
+The GtkObject type provides a mechanism for associating arbitrary
+amounts of data with an object. The data is associated with the object
+using a character string key. The functions @code{gtk_object_set_data},
+@code{gtk_object_get_data}, and @code{gtk_object_remove_data} are the
+interface to this mechanism. Two other routines,
+@code{gtk_object_set_user_data} and @code{gtk_object_get_user_data},
+exist as convenience functions which simply use the same mechanism.
+
+@deftypefun void gtk_object_set_data (GtkObject *@var{object}, const char *@var{key}, gpointer @var{data})
+Associate @var{data} with @var{key} in the data list of @var{object}.
+@end deftypefun
+
+@deftypefun gpointer gtk_object_get_data (GtkObject *@var{object}, const char *@var{key})
+Retrieve the data associated with @var{key} in the data list of @var{object}.
+@end deftypefun
+
+@deftypefun void gtk_object_remove_data (GtkObject *@var{object}, const char *@var{key})
+Remove the data associated with @var{key} in the data list of @var{object}.
+@end deftypefun
+
+@deftypefun void gtk_object_set_user_data (GtkObject *@var{object}, gpointer @var{data})
+Sets @var{data} into the @code{user_data} field of @var{object}.
+@end deftypefun
+
+@deftypefun gpointer gtk_object_get_user_data (GtkObject *@var{object})
+Returns the @code{user_data} field of @var{object}.
+@end deftypefun
+
+The GtkObject type also provides a mechanism for specifying
+initialization values for fields. This general mechanism is called
+object value stacks. The reason for using value stacks is that they can
+simplify the life of the programmer. For instance, by default widgets
+are non-visible when created. However, the ``visible'' value for widgets
+may be specified so that widgets are made visible when created. (FIXME:
+unfinished).
+
+@deftypefun void gtk_object_value_stack_new (guint @var{object_type}, const gchar *@var{value_id}, GtkParamType @var{value_type})
+@end deftypefun
+
+@deftypefun void gtk_object_push_value (guint @var{object_type}, const gchar *@var{value_id}, @dots{})
+Push a value on the value stack specified by @var{object_type} and
+@var{value_id}. The type of value is implicitly given in the context of
+@var{object_type} and @var{value_id}. (That is, it is not specified
+explicitly in the function call). Only a single extra argument is
+expected which is the data which is to be placed on the stack.
+@end deftypefun
+
+@deftypefun void gtk_object_pop_value (guint @var{object_type}, const gchar *@var{value_id})
+Pop a value of the value stack specified by @var{object_type} and
+@var{value_id}.
+@end deftypefun
+
+@deftypefun gint gtk_object_peek_value (guint @var{object_type}, const gchar *@var{value_id}, gpointer @var{data})
+Peek at the value on the top of the value stack specified by
+@var{object_type} and @var{value_id}. The @var{data} argument is
+interpreted as the location of where to place the ``peeked'' data. For
+instance, if the peeked data is of type @code{GTK_PARAM_POINTER}, then
+@var{data} will be a pointer to a pointer. If the value stack is empty
+or does not exist or an error occurs, @code{gtk_object_peek_value} will
+return @code{FALSE}. On success it will return @code{TRUE}.
+@end deftypefun

+@comment node-name, next, previous, up
+@chapter Signals Overview
+@cindex Signals
+
+Signals are GTK's method for objects to perform callbacks. A signal is
+an event which occurs upon an object. The programmer can connect to a
+signal of an object which involves specifying a function to be called
+when that signal is emitted in the specified object.
+
+When a signal is emitted, both the class function associated with the
+signal (when it was defined) and all signal handlers installed for that
+signal on the particular object emitting the signal are called. The
+widget programmer can specify whether the class function is to be called
+before after or both before and after the signal handlers installed by
+the widget user. The widget user can, however, specify that their signal
+handler is to be run after the class function (using the ``_after''
+signal connection routines). Any signal handling function can emit the
+same signal on the same object while it is running causing that signal
+emittion to either restart or to run recursively. Additionally, signal
+emittion can be terminated prematurely. While both such abilities are
+rarely used, they do allow for greater flexibility in regards to
+signals. For instance, a programmer can attach to the key press event
+signal and intercept all tab key presses from a widget. This particular
+example is used in the file selection dialog to implement tab completion
+of filenames and prevent the entry widget from inserting the tab into
+its buffer.
+
+Signals are selected using either an integer identifier or a character
+string name. It is convention to name the signal the same as the class
+function which is associated with it. There are two versions of most of
+the signal functions, one which takes an integer identifier and one
+which takes a character string name for the signal.
+
+@deftypefun gint gtk_signal_new (gchar *@var{name}, GtkSignalRunType @var{run_type}, gint @var{object_type}, gint @var{function_offset}, GtkSignalMarsahller @var{marshaller}, GtkParamType @var{return_val}, gint @var{nparams}, @dots{})
+Create a new signal and give it the character string identifier
+@var{name}. @var{name} needs to be unique in the context of
+@var{object_type}'s branch of the class hierarchy. That is,
+@var{object_type} cannot create a signal type with the same name as a
+signal type created by one of its parent types.
+
+@var{run_type} specifies whether the class function should be run before
+(@code{GTK_RUN_FIRST}), after (@code{GTK_RUN_LAST}) or both before and
+after normal signal handlers (@code{GTK_RUN_BOTH}). Additionally, the
+@code{GTK_RUN_NO_RECURSE} value can be or'ed with any of those values to
+specify that the signal should not be recursive. By default, emitting
+the same signal on the same widget will cause the signal to be emitted
+twice. However, if the @code{GTK_RUN_NO_RECURSE} flag is specified,
+emitting the same signal on the same widget will cause the current
+signal emittion to be restarted. This allows the widget programmer to
+specify the semantics of signal emittion on a per signal
+basis. (The @code{GTK_RUN_NO_RECURSE} flag is used by the GtkAdjustment
+widget).
+
+The @var{function_offset} is the byte offset from the start of the class
+structure to the class function field within the class structure. The
+easiest means to compute this offset is by using the
+@code{GTK_SIGNAL_OFFSET} macro which takes the class structure type as
+the first argument and the field as the second argument. For example,
+@code{GTK_SIGNAL_OFFSET (GtkObjectClass, destroy)} will give the offset
+of the @code{destroy} class function within the
+@code{GtkObjectClass}. Note: An offset is specified instead of an
+absolute location since there will be multiple instances of a class
+structure being referenced. (The @code{GtkWidgetClass} structure ``is
+a'' @code{GtkObjectClass} structure, etc.)
+
+The @var{marshaller} function is used to invoke a signal handler. Since
+signal handlers may take different parameters and return values and a
+general mechanism for invoking them is not apparent, the approach of
+making the signal creator responsible for invoking the signal handler
+was taken. (FIXME: unfinished).
+
+The @var{return_val} and @var{nparams} and the remaining arguments
+specify the return value and the arguments to the signal handler
+respectively. Note: There is an implicit first argument to every signal
+handler which is the widget the signal has been emitted from. The
+variable argument list (@var{@dots{}}) specifies the types of the
+arguments. These can be one of @code{GTK_PARAM_CHAR},
+@code{GTK_PARAM_SHORT}, @code{GTK_PARAM_INT}, @code{GTK_PARAM_LONG},
+@code{GTK_PARAM_POINTER} or @code{GTK_PARAM_FUNCTION}. It is undefined
+to specify @code{GTK_PARAM_NONE} as an argument type, however it is ok
+to use @code{GTK_PARAM_NONE} for @var{return_val}. (This corresponds to
+returning a @code{void}).
+
+@code{gtk_signal_new} returns the integer identifier of the newly
+created signal. Signal identifiers start numbering at 1 and increase
+upwards. A value of -1 will be returned if an error occurs.
+
+@strong{Note:} @code{gtk_signal_new} is only needed by widget writers. A
+normal user of GTK will never needed to invoke this function.
+@end deftypefun
+
+@deftypefun gint gtk_signal_lookup (gchar *@var{name}, gint @var{object_type})
+Returns the integer identifier for the signal referenced by @var{name}
+and @var{object_type}. If @var{object_type} does not define the signal
+@var{name}, then the signal is looked for in @var{object_type}'s parent
+type recursively.
+@end deftypefun
+
+@deftypefun gint gtk_signal_emit (GtkObject *@var{object}, gint @var{signal_type}, @dots{})
+Emit the signal specified by the integer identifier @var{signal_type}
+from @var{object}. If an error occurs, @code{gtk_signal_emit} will
+return @code{FALSE} and will return @code{TRUE} on success. The signal
+definition determines the parameters passed in the variable argument
+list (@code{@dots{}}). For example, if the signal is defined as:
+
+@example
+ gint (* event) (GtkWidget *widget, GdkEvent *event);
+@end example
+
+Then a call to emit the ``event'' signal would look like:
+
+@example
+ GdkEvent event;
+ gint return_val;
+ @dots{}
+ gtk_signal_emit (some_object,
+ gtk_signal_lookup ("event",
+ GTK_OBJECT_TYPE (some_object)),
+ &event, &return_val);
+@end example
+
+Notice that the @code{widget} argument is implicit in that the first
+argument to every signal is a type derived from @code{GtkObject}. The
+@var{return_val} argument is actually a pointer to the return value type
+since the signal mechanism needs to be able to place the return value in
+an actual location. And lastly, the @code{gtk_signal_lookup} call is
+normally avoided by using the @code{gtk_signal_emit_by_name} function
+instead. @code{gtk_signal_emit} is normally used internally by widgets
+which know the signal identifier (since they defined the signal) and can
+therefore side-step the cost of calling @code{gtk_signal_lookup}.
+@end deftypefun
+
+@deftypefun gint gtk_signal_emit_by_name (GtkObject *@var{object}, gchar *@var{name}, @dots{})
+Similar to @code{gtk_signal_emit} except that the signal is referenced
+by @var{name} instead of by its integer identifier.
+@end deftypefun
+
+@deftypefun void gtk_signal_emit_stop (GtkObject *@var{object}, gint @var{signal_type})
+Stop the emission of the signal @var{signal_type} on
+@var{object}. @var{signal_type} is the integer identifier for the signal
+and can be determined using the function
+@code{gtk_signal_lookup}. Alternatively, the function
+@code{gtk_signal_emit_stop_by_name} can be used to refer to the signal
+by name. Attempting to stop the emission of a signal that isn't being
+emitted does nothing.
+@end deftypefun
+
+@deftypefun void gtk_signal_emit_stop_by_name (GtkObject *@var{object}, gchar *@var{name})
+Similar to @code{gtk_signal_emit_stop} except that the signal is
+referenced by @var{name} instead of by its integer identifier.
+@end deftypefun
+
+@deftypefun gint gtk_signal_connect (GtkObject *@var{object}, gchar *@var{name}, GtkSignalFunc @var{func}, gpointer @var{func_data})
+Connects a signal handling function to a signal emitting
+object. @var{func} is connected to the signal @var{name} emitted by

+usage is to connect the ``destroy'' signal of dialog to the ``clicked''
+signal emitted by a ``close'' button in the dialog. That is, the
+``clicked'' signal emitted by the button will caused the ``destroy''
+signal to be emitted for the dialog. This is also the ``right'' way to
+handle closing of a dialog since the ``destroy'' signal will be sent if

+@chapter Widget Overview
+@cindex Widgets
+
+
+Widgets are the general term used to describe user interface objects. A
+widget defines a class interface that all user interface objects conform
+to. This interface allows a uniform method for dealing with operations
+common to all objects such as hiding and showing, size requisition and
+allocation and events.
+
+The common interface that widgets must adhere to is described by the
+GtkWidget and GtkWidgetClass structure. For the purposes of using GTK
+these structures can be considered read-only and, for the most part,
+opaque.
+
+All widget creation routines in GTK return pointers to GtkWidget
+structures. In reality, all widget creation routines create structures
+that can be viewed as equivalent to the GtkWidget structure, but often
+have contain additional information. @xref{Object Implementation}
+
+The widgets available for use are implemented in a hierarchy. Several
+widgets exist solely as common bases for more specific widgets. For
+example, it is not possible to create a ruler widget itself, but the
+ruler widget provides a base and functionality common to the horizontal
+and vertical rulers.
+
+The available widgets (in alphabetical order):
+

+@section The alignment widget
+
+
+@subsection Description
+
+The alignment widget is a container (@pxref{GtkContainer}) derived from
+the bin widget (@pxref{GtkBin}). Its entire purpose is to give the
+programmer flexibility in how the child it manages is positioned when a
+window is resized.
+
+Normally, a widget is allocated at least as much size as it
+requests. (@pxref{GtkContainer} for a discussion of geometry
+management). When a widget is allocated more size than it requests there
+is a question of how the widget should expand. By convention, most GTK
+widgets expand to fill their allocated space. Sometimes this behavior is
+not desired. The alignment widget allows the programmer to specify how a
+widget should expand and position itself to fill the area it is
+allocated.
+
+@subsection Options
+
+@defopt xscale
+@defoptx yscale
+The @var{xscale} and @var{yscale} options specify how to scale the child
+widget. If the scale value is 0.0, the child widget is allocated exactly
+the size it requested in that dimension. If the scale value is 1.0, the
+child widget is allocated all of the space in a dimension. A scale value
+of 1.0 for both x and y is equivalent to not using an alignment widget.
+@end defopt
+
+@defopt xalign
+@defoptx yalign
+The @var{xalign} and @var{yalign} options specify how to position the
+child widget when it is not allocated all the space available to it
+(because the @var{xscale} and/or @var{yscale} options are less than
+1.0). If an alignment value is 0.0 the widget is positioned to the left
+(or top) of its allocated space. An alignment value of 1.0 positions the
+widget to the right (or bottom) of its allocated space. A common usage
+is to specify @var{xalign} and @var{yalign} to be 0.5 which causes the
+widget to be centered within its allocated area.

+@section The box widget
+
+
+@subsection Description
+
+The box widget is a container (@pxref{GtkContainer}) derived from the
+container widget. It is an abstract base class used by the horizontal
+box (@pxref{GtkHBox}) and vertical box (@pxref{GtkVBox}) widgets to
+provide a base of common functionality.
+
+A box provides an abstraction for organizing the position and size of
+widgets. Widgets in a box are layed out horizontally or vertically. By
+using a box widget appropriately, a programmer can control how widgets
+are positioned and how they will be allocated space when a window gets
+resized.
+
+The key attribute of boxes is that they position their children in a
+single row (horizontal boxes) or column (vertical boxes). In the case of
+horizontal boxes, all children are stretched vertically. The vertical
+size of the box is determined by the largest vertical requisition of all
+of its children. Similarly, a vertical box streches all of its children
+horizontally. The horizontal size (of the vertical box) is determined by
+the largest horizontal requisition of all of its children. An alignment
+widget (@pxref{GtkAlignment}) can be used to control child allocation
+more precisely on a per child basis.
+
+The second attribute of boxes is how they expand children. In the case
+of a horizontal box, the main control is over how children are expanded
+horizontally to fill the allocated area. (The rest of this discussion
+will focus on horizontal boxes but it applies to vertical boxes as
+well).
+
+There are two flags which can be set controlling how a widget is
+expanded horizontally in a horizontal box. These are the @code{expand}
+and @code{fill}. There operation is fairly simple. If @code{expand} is
+set, the childs potentially allocated area will expand to fill available
+space. If @code{fill} is set, the childs actual allocated area will be
+its potentially allocated area. There is a difference between
+the potentially area (which is the area the box widget sets aside for
+the child) and the actual allocated area (which is the area the box
+widget actual allocates for the widget via
+@code{gtk_widget_size_allocate}).
+
+The allocation of space to children occurs as follows (for horizontal
+boxes):
+@enumerate
+@item
+All children are allocated at least their requested size horizontally
+and the maximum requested child size vertically.
+
+@item
+Any child with the @code{expand} flag set is allocated @code{extra_width
+/ nexpand_children} extra pixels horizontally. If the @code{homogeneous}
+flag was set, all children are considered to have the @code{expand} flag
+set. That is, all children will be allocated the same area.The
+horizontal box is a fair widget and, as such, divides up any extra
+allocated space evenly among the ``expand'' children. (Those children
+which have the @code{expand} flag set). The exception occurs when
+@code{extra_width / nexpand_children} does not divide cleanly. The extra
+space is given to the last widget.
+
+@item
+@code{spacing} number of pixels separate each child. Note: The
+separation is between the potentially allocated area for each child and
+not the actual allocated area. The @code{padding} value associated with
+each child causes that many pixels to be left empty to each side of the
+child.
+
+@item
+If a child has the @code{fill} flag set it is allocated its potentially
+allocated area. If it does not, it is allocated its requested size
+horizontally and centered within its potentially allocated area. Its
+vertical allocation is still the maximum requested size of any child.
+
+@item
+Children placed at the start of the box are placed in order of addition
+to the box from left to right in the boxes allocated area.. Children
+placed at the end of the box are placed in order of addition from right
+to left in the boxes allocated area.

+@section Macros defined by all objects
+
+There are three macros that are defined by all object types. The first
+two are used for performing casts and the last is for querying whether
+an object is of a particular type. These macros are both conveniences
+and debugging tools. If the GTK library was compiled with @code{NDEBUG}
+defined as a preprocessor symbol (via the -DNDEBUG to cc), then the
+macros check the object type and emit a warning if the cast is
+invalid. Doing such checking is fairly expensive since the cast macros
+are used everywhere in GTK and would normally be turned off in a public
+release of a product. Note: The functions below are indeed macros, but
+they may be considered functions for most purposes.
+
+@deftypefun Gtk<ObjectType>* GTK_<OBJECT_TYPE> (gpointer @var{obj})
+Cast a generic pointer to @code{Gtk<ObjectType>*}. This function is
+provided in order to be able to provide checking during development
+stages of code development since it is possible to examine the actual
+type of object (using @code{gtk_type_is_a}) before performing the cast.
+@end deftypefun
+
+@deftypefun Gtk<ObjectType>Class* GTK_<OBJECT_TYPE>_CLASS (gpointer @var{class})
+Cast a generic pointer to @code{Gtk<ObjectType>Class*}. Like
+@code{GTK_<ObjectType>}, this function is, in reality, a macro.
+@end deftypefun
+
+@deftypefun gint GTK_IS_<ObjectType> (gpointer @var{obj})
+Determine if a generic pointer refers to a @code{Gtk<ObjectType>}
+object. This function is, in reality, a macro wrapper around the
+@code{gtk_type_is_a} function (@pxref{Objects}).

+@section The simplest GTK program
+
+
+The 16 line GTK program shown below is just about the simplest possible
+program which uses GTK. (Well, technically, you don't have to create the
+window and it would still be a program which uses GTK). The program,
+when compiled and run, will create a single window 200x200 pixels in
+size. The program does not exit until its is explicitly killed using the
+shell or a window manager function.
+
+@example
+#include <gtk/gtk.h>
+
+int
+main (int argc, char *argv[])
+@{
+ GtkWidget *window;
+
+ gtk_init (&argc, &argv);
+
+ window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
+ gtk_widget_show (window);
+
+ gtk_main ();
+
+ return 0;
+@}
+@end example
+
+The first point of interest in this program is the standard
+initialization line.
+
+@example
+ gtk_init (&argc, &argv);
+@end example
+
+Almost every GTK program will contain such a line. GTK will initialize
+itself and GDK and remove any command line arguments it recognizes from
+@var{argc} and @var{argv}.
+
+The next two lines of code create and display a window.
+
+@example
+ window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
+ gtk_widget_show (window);
+@end example
+
+The @code{GTK_WINDOW_TOPLEVEL} argument specifies that we want the
+window to undergo window manager decoration and placement. One might be
+lead to think that the window, since it has no children, would be 0x0
+pixels in size. But, this is not the case because a window that has no
+children defaults to 200x200 pixels in size. Mainly because 0x0 windows
+are annoying to manipulate or even see in some cases.
+
+The last line enters the GTK main processing loop.
+
+@example
+ gtk_main ();
+@end example
+
+Normally, @code{gtk_main} is called once and the program should exit
+when it returns. @xref{Initialization and exit}.

+@chapter Object internals
+@cindex Object Implementaton
+
+Objects (or the @code{GtkObject} type) and the class hierarchy in
+general is implemented via a hierarchy of structs and type casting. Be
+aware that when classes are mentioned it is the conceptual idea of
+classes that is being referred to. GTK is written entirely in C which
+provides no direct support for classes.
+
+The first part to the class mechanism is the object fields. These are
+fields that will be used on a per object basis. For example, the widget
+type contains a field for the widgets parent. Every derived type needs a
+reference to its parent type. A descendant class of @code{GtkObject}
+would define itself like:
+
+@example
+struct Descendant
+@{
+ GtkObject object;
+
+ @dots{}
+@};
+@end example
+
+It is important to note that the @code{GtkObject} field needs to appear
+first in the descendant type structure. This allows pointers to objects
+of type @code{Descendant} to be cast to pointers to @code{GtkObjects}'s
+and vice-versa.
+
+The second part to the class mechanism is the class fields. These fields
+are defined on a per class basis. In the case of widgets, the class
+fields are all the ``virtual'' functions for widgets. The
+@code{GtkObject} class defines the @code{destroy} virtual function and
+the necessary fields for the signal mechanism as well as a field for
+determining the runtime type of an object. A virtual function is
+semantically the same as it is in C++. That is, the actual function that
+is called is determined based on the type of the object. Or, more
+specifically, the actual function call depends on the class structure
+that is pointed to by the @code{klass} field of the @code{GtkObject}
+structure.
+
+To see how the class fields work it is necessary to see the object
+fields for a @code{GtkObject}. The @code{GtkObject} type is defined as
+follows:
+
+@example
+typedef struct _GtkObject GtkObject;
+
+struct _GtkObject
+@{
+ guint32 flags;
+ GtkObjectClass *klass;
+ gpointer object_data;
+@};
+@end example
+
+The @code{class} field actually points to a class structure derived from
+@code{GtkObjectClass}. By convention, each new type defines its own
+class structure even if it is unnecessary. As an example, the
+hypothetical @code{Descendant} class would define its class structure
+as:
+
+@example
+struct DescendantClass
+@{
+ GtkObjectClass parent_class;
+
+ @dots{}
+@};
+@end example
+
+It is convention to name the parent class field (@code{GtkObjectClass}
+in this case), @code{parent_class}. For the same reason as stated above
+for the object structure, the parent class field must be the first field
+in the class structure.
+
+@strong{Note:} GTK assumes that the first field in a structure will be
+placed by the compiler at the start of the structure. This is certainly
+true for gcc, however, from my precursory reading of the C standard I
+was unable to come to a definite conclusion as to whether this was
+required or simply done for simplicity. I'm not too worried about this
+assumption, though, as every C compiler I've ever encountered would work
+with GTK.
+
+The @code{flags} field of the @code{GtkObject} structure is used to keep
+track of a relatively few object flags and is also used by the
+@code{GtkWidget} type to store additional flags. At this time, the upper
+16 bits of the flags field are reserved but unused.
+
+The @code{object_data} field of the @code{GtkObject} structure is an
+opaque pointer used by the object data mechanism. In truth, it is a
+pointer to the beginning of the data list which is composed of the
+following structures.
+
+@example
+typedef struct _GtkObjectData GtkObjectData;
+
+struct _GtkObjectData
+@{
+ guint id;
+ gpointer data;
+ GtkObjectData *next;
+@};
+@end example
+
+The data mechanism allows arbitrary data to be associated with a
+character string key in any object. A hash table is used to transform
+the character string key into the data id and then a search through the
+list is made to see if the data exists. The assumption being that the
+data list will usually be short and therefore a linear search is
+ok. Future work on the data mechanism might make use of a resizable
+array instead of a linked list. This would shrink the overhead of the
+@code{GtkObjectData} structure by 4 bytes on 32 bit architectures.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble. Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+% @multitable @columnfractions .25 .3 .45
+% @item ...
+%
+% Numbers following @columnfractions are the percent of the total
+% current hsize to be used for each column. You may use as many
+% columns as desired.
+
+
+% Or use a template:
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item ...
+% using the widest term desired in each column.
+%
+% For those who want to use more than one line's worth of words in
+% the preamble, break the line within one argument and it
+% will parse correctly, i.e.,
+%
+% @multitable {Column 1 template} {Column 2 template} {Column 3
+% template}
+% Not:
+% @multitable {Column 1 template} {Column 2 template}
+% {Column 3 template}
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab, @multitable or @end multitable do not need to be on their
+% own lines, but it will not hurt if they are.
+
+% Sample multitable:
+
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item first col stuff @tab second col stuff @tab third col
+% @item
+% first col stuff
+% @tab
+% second col stuff
+% @tab
+% third col
+% @item first col stuff @tab second col stuff
+% @tab Many paragraphs of text may be used in any column.
+%
+% They will wrap at the width determined by the template.
+% @item@tab@tab This will be in third column.
+% @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+% to baseline.
+% 0pt means it depends on current normal line spacing.

+Usage: $progname [OPTION]... --mode=link LINK-COMMAND...
+
+Link object files or libraries together to form another library, or to
+create an executable program.
+
+LINK-COMMAND is a command using the C compiler that you would use to create
+a program from several object files.
+
+The following components of LINK-COMMAND are treated specially:
+
+ -all-static do not do any dynamic linking at all
+ -allow-undefined allow a libtool library to reference undefined symbols
+ -dlopen FILE \`-dlpreopen' FILE if it cannot be dlopened at runtime
+ -dlpreopen FILE link in FILE and add its symbols to dld_preloaded_symbols
+ -export-dynamic allow symbols from OUTPUT-FILE to be resolved with dlsym(3)
+ -LLIBDIR search LIBDIR for required installed libraries
+ -lNAME OUTPUT-FILE requires the installed library libNAME
+ -o OUTPUT-FILE create OUTPUT-FILE from the specified objects
+ -rpath LIBDIR the created library will eventually be installed in LIBDIR
+ -static do not do any dynamic linking of libtool libraries
+ -version-info CURRENT[:REVISION[:AGE]]
+ specify library version info [each variable defaults to 0]
+
+All other options (arguments beginning with \`-') are ignored.
+
+Every other argument is treated as a filename. Files ending in \`.la' are
+treated as uninstalled libtool libraries, other files are standard or library
+object files.
+
+If the OUTPUT-FILE ends in \`.la', then a libtool library is created, only
+library objects (\`.lo' files) may be specified, and \`-rpath' is required.
+
+If OUTPUT-FILE ends in \`.a', then a standard library is created using \`ar'
+and \`ranlib'.
+
+If OUTPUT-FILE ends in \`.lo' or \`.o', then a reloadable object file is
+created, otherwise an executable program is created.

+Usage: $progname [OPTION]... --mode=link LINK-COMMAND...

+LINK-COMMAND is a command using the C compiler that you would use to create
+a program from several object files.
+
+The following components of LINK-COMMAND are treated specially:
+
+ -all-static do not do any dynamic linking at all
+ -allow-undefined allow a libtool library to reference undefined symbols
+ -dlopen FILE \`-dlpreopen' FILE if it cannot be dlopened at runtime
+ -dlpreopen FILE link in FILE and add its symbols to dld_preloaded_symbols
+ -export-dynamic allow symbols from OUTPUT-FILE to be resolved with dlsym(3)
+ -LLIBDIR search LIBDIR for required installed libraries
+ -lNAME OUTPUT-FILE requires the installed library libNAME
+ -o OUTPUT-FILE create OUTPUT-FILE from the specified objects
+ -rpath LIBDIR the created library will eventually be installed in LIBDIR
+ -static do not do any dynamic linking of libtool libraries
+ -version-info CURRENT[:REVISION[:AGE]]
+ specify library version info [each variable defaults to 0]
+
+All other options (arguments beginning with \`-') are ignored.
+
+Every other argument is treated as a filename. Files ending in \`.la' are
+treated as uninstalled libtool libraries, other files are standard or library
+object files.
+
+If the OUTPUT-FILE ends in \`.la', then a libtool library is created, only
+library objects (\`.lo' files) may be specified, and \`-rpath' is required.
+
+If OUTPUT-FILE ends in \`.a', then a standard library is created using \`ar'
+and \`ranlib'.
+
+If OUTPUT-FILE ends in \`.lo' or \`.o', then a reloadable object file is
+created, otherwise an executable program is created.
