Cross-platform toolkit for creating graphical user interfaces.

GTK+ is a GUI Toolkit for creating graphical user interfaces.

This package provides a complete set of widgets suitable for projects ranging from small one-off tools to complete application suites. In addition to basic widgets, such as buttons, check boxes, and text entries, it also provides Model-View-Controller (MVC) APIs for tree views, multi-line text fields, and menu and toolbar actions.

GTK+ is the primary library used to construct user interfaces in GNOME. Its name stands for "GIMP Tool Kit", as originally it was explicitly written for that image manipulation program, and later extracted from it as a stand-alone library.

Third-party language bindings designed for the GNU system are provided by the Guile-Gnome project.
