Questions tagged [gtk]

GTK (formerly GTK+) is a toolkit for creating graphical user interfaces (GUIs) with cross platform compatibility and an easy to use API.

GTK is written in C, and has bindings to many other popular programming languages such as C++ (), Python (, ), C# (), and Perl, among others. GTK+ is licensed under the GNU LGPL 2.1, allowing development of both free and proprietary software with GTK+ without any license fees or royalties.

"GTK" stands for GIMP Tool Kit. It was originally developed to serve as the widget set for The GIMP, the GNU Image Manipulation Program. In the intervening years its usage has expanded greatly.

This tag should be used for questions about GTK in general. For more specific questions regarding how a certain version works, use or .
