Download GTK3 3.4.3 / 3.5.2

GTK3, GUI Toolkit.

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+ 3.0 is a major new version of GTK+, containing many changes :

GDK no longer wraps the antiquated X11 drawing API; but only exclusively relies on cairo for all our drawing needs now. Several other X11-centric concepts such as GCs, colormaps and pixmaps has been removed as well.

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 transitions.
