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 a
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+ 3 will be incorporated into version 3
of the GNOME desktop.

What's new in GTK+ 3

GTK+ 3 is a major new version of GTK+, containing far too many
changes to list them all here. The major highlights include:

* Cairo drawing throughout. GDK no longer wraps the antiquated
X11 drawing API; we've made a clean break and exclusively rely
on cairo for all our drawing needs now. This has also enabled us
to remove several other X11-centric concepts such as GCs, colormaps
and pixmaps.

* Modern input device handling. The input device handling in GDK has
long been a sadly neglected area. This has changed; with 3.0, GTK+
steps into the modern world of XI2 with full support for multiple
pointers, keyboards and other gizmos.

* A new theming API which sports a familiar CSS syntax for theme
configuration and other improvements such as animated state

* More flexible geometry management, with support for height-for-width,
for both widgets and cell renderers.

* Multiple backend support for GDK. With GTK+ 2.x, you had to recompile
your application to have it work with a different GDK backend.
In GTK+ 3, multiple GDK backends can be built into a single library
and selected at runtime.

* Easy application support. With the integration of D-Bus support in
GIO, we could finally add a GtkApplication class that handles a lot
of the platform integration aspects of writing an application, such
as keeping track of open windows, ensuring uniqueness, exporting
actions, etc.

* Of course, there's some new widgets as well, such as a switch and
an application chooser.

Common questions:

GTK+ 3 is a major new version of GTK+, changing the ABI and
the API compared to GTK+ 2.x. This means that GTK+ 2.x applications
will need some adjustments before they can be used with GTK+ 3.
