Using GTK+ on DirectFB
Using GTK+ on DirectFB — DirectFB-specific aspects of using GTK+
The DirectFB port of GTK+ is an implementation of GDK (and therefore GTK+) on top of the DirectFB libraries.
Like the obsolete linux-fb port of GTK+, it runs on the Linux framebuffer, but the DirectFB libraries provide additional features like hardware graphics acceleration, input device handling and abstraction and an integrated windowing system.
