General Information =================== This is GTK+ version @GTK_VERSION@. GTK+ is a multi-platform toolkit for creating graphical user interfaces. Offering a complete set of widgets, GTK+ is suitable for projects ranging from small one-off projects to complete application suites. GTK+ is free software and part of the GNU Project. However, the licensing terms for GTK+, the GNU LGPL, allow it to be used by all developers, including those developing proprietary software, without any license fees or royalties. The official download locations are: ftp://ftp.gtk.org/pub/gtk http://download.gnome.org/sources/gtk+ The official web site is: http://www.gtk.org/ Information about mailing lists can be found at http://www.gtk.org/mailing-lists.php Installation ============ See the file 'INSTALL' How to report bugs ================== Bugs should be reported to the GNOME bug tracking system. (http://bugzilla.gnome.org, product glib.) You will need to create an account for yourself. In the bug report please include: * Information about your system. For instance: - What operating system and version - For Linux, what version of the C library And anything else you think is relevant. * How to reproduce the bug. If you can reproduce it with one of the test programs that are built in the tests/ subdirectory, that will be most convenient. Otherwise, please include a short test program that exhibits the behavior. As a last resort, you can also provide a pointer to a larger piece of software that can be downloaded. * If the bug was a crash, the exact text that was printed out when the crash occured. * Further information such as stack traces may be useful, but is not necessary. Patches ======= Patches should also be submitted to bugzilla.gnome.org. If the patch fixes an existing bug, add the patch as an attachment to that bug report. Otherwise, enter a new bug report that describes the patch, and attach the patch to that bug report. Patches should be in unified diff form. (The -up option to GNU diff.) Release notes for 3.6 ===================== * Now follows the XDG Base Directory specification for user configuration and data files. In detail, * $XDG_CONFIG_HOME/gtk-3.0/custom-papers is the new location for $HOME/.gtk-custom-papers * $XDG_CONFIG_HOME/gtk-3.0/bookmarks is the new location for $HOME/.gtk-bookmarks * $XDG_DATA_HOME/themes is preferred over $HOME/.themes * $XDG_DATA_HOME/icons is preferred over $HOME/.icons. Existing files from the old location will still be read if the new location does not exist. * $HOME/.gtk-3.0 is no longer in the default module load path. If you want to load modules from there, add it to the GTK_PATH environment variable. Release notes for 3.4 ===================== * Scroll events have been separated from button events, and smooth scrolling has been added with a separate event mask. Widgets now need to have either GDK_SCROLL_MASK or GDK_SMOOTH_SCROLL_MASK in their event mask to receive scroll events. In addition, the GdkScrollDirection enumeration has gained a new member, GDK_SCROLL_SMOOTH, so switch statements will have to be amended to cover this case. * GTK+ now uses instead of in keyboard accelerators, for improved cross-platform handling. This should not affect applications, unless they parse or create these accelerator manually. * The tacit assumption that the Alt key corresponds to the MOD1 modifier under X11 is now a hard requirement. * The beagle search backend for the file chooser has been dropped. Tracker is the only supported search backend on Linux now. * GtkNotebook has been changed to destroy its action widgets when it gets destroyed itself. If your application is using action widgets in notebooks, you may have to adjust your code to take this into account. * GtkApplication no longer uses the gtk mainloop wrappers, so it is no longer possible to use gtk_main_quit() to stop it. * The -uninstalled variants of the pkg-config files have been dropped. * Excessive dependencies have been culled from Requires: lines in .pc files. Dependent modules may have to declare dependencies that there were getting 'for free' in the past. Release notes for 3.2 ===================== * The accessible implementations for GTK+ widgets have been integrated into libgtk itself, and the gail module does not exist anymore. This change should not affect applications very much. Release notes for 3.0 ===================== * GTK+ 3 is a major new version of GTK+, which is parallel installable with GTK+ 2.x. For information about porting applications from GTK+ 2.x to GTK+ 3, see the file: docs/reference/gtk/html/migrating.html Or online at: http://library.gnome.org/devel/gtk/3.0/migrating.html * Note that the library sonames in this release have been changed from libgtk-3.0 and libgdk-3.0 to libgtk-3 and libgdk-3, to prevent the library versions from going backwards, compared to the 2.90/91/99 releases. Applications will have to be recompiled.
