[~andy/gtk] / ChangeLog

Mon Nov 24 1997 Jay Painter <jpaint@serv.net>
        gtk-dairiki-971117-2.patch
        gtk/gtkaspectframe.c (gtk_aspect_frame_size_allocate): When
        computing new dimensions of the subwidget, round to nearest
        integer rather than truncating.

Mon Nov 24 1997 Jay Painter <jpaint@serv.net>
        gtk-dairiki-971117-1.patch
        * gtk/gtkvruler.c (gtk_vruler_draw_ticks):
        * gtk/gtkhruler.c (gtk_hruler_draw_ticks): Ensure that subticks
        always are drawn when they should be (sometimes they were getting
        drawn with zero length --- invisible).  Also clear rectangle
        behind text labels to ensure they don't touch or overlap ticks. 

Mon Nov 24 1997 Jay Painter <jpaint@serv.net>
        * gtk/gtkaspectframe.c (gtk_aspect_frame_set): 
        gtk-dairiki-971117-0.patch
        Clear window when aspect ratio or alignment is changed.

Mon Nov 24 1997 Jay Painter <jpaint@serv.net>
        * gtk/gtkobject.h: fixed GTK_OBJECT_NSIGNALS macro

Mon Nov 24 1997 Jay Painter <jpaint@serv.net>
        * gtk/gtklabel.h: modified gtklabel to clip its drawing to
        its given area, now it will always draw in the area it's 
        been given and clip accordingly.  Note: this may cause
        the a label to disappear on widgets which don't give their
        child labels proper area!

Mon Nov 17 1997 Jay Painter <jpaint@serv.net>
        * 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
        * 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.

Sun Dec  1 01:31:01 1996  Peter Mattis  <pmattis@charnley.HIP.Berkeley.EDU>

        * Started ChangeLog
