What is GTK+

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 tools to
complete application suites.

GTK+ has been designed from the ground up to support a range
of languages, not only C/C++. Using GTK+ from languages such
as Perl and Python (especially in combination with the Glade
GUI builder) provides an effective method of rapid application

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. GTK+ is the
only 100% free-of-cost open source industrial-strength GUI
toolkit available today.

Since its origins as the toolkit for the GNU Image
Manipulation Program (GIMP), GTK+ has been used in a wide
range of software. Notably, GTK+ is the foundation of the
GNOME desktop; GTK+ 2.22 will be incorporated into version
2.32 of the GNOME desktop.

What's new in GTK+ 2.22

GTK+ 2.22 adds new functionality while maintaining source and binary
compatibility with earlier GTK+ 2.x releases.
Highlights of new features and improvements in GTK+ 2.22 are:

 - gdk-pixbuf has been separated into its own module again.
   Find it here:

 - GTK+ and GDK have gained a considerable number of accessors,
   and more APIs that are slated for removal in GTK+ 3 have been
   marked as deprecated.
   These allow to prepare applications for a port to GTK+ 3, using

 - A few new cairo-related functions have been introduced, such as
   gdk_window_create_similar_surface() and
   to facilitate the move to entirely cairo-based drawing in GTK+ 3.
   Most drawing done by GTK+ itself has already been ported from
   GDK drawing APIs to cairo.

announcements for the 2.21.x development releases:
