With the upcoming GNOME 3.16 release and its GTK+ 3.16 tool-kit there is native OpenGL support and a new GTKGLArea widget.

The GTK+ 3.16 OpenGL support has been covered in a number of Phoronix articles since last year, but for GTK+ developers out there you're probably wondering how to start making use of this OpenGL support within the GTK+ support. If you haven't yet experimented with GTK's new OpenGL support, Emmanuele Bassi has written a lengthy and very informative blog post about all of the essential facts for this new feature and how to get started.

Bassi's blog post govers over some simple GTK+ OpenGL code, transitioning from older GTK2+ OpenGL code, and other important details like why GTK+ requires core OpenGL profile contexts.

If you're interested in a how-to for using OpenGL with GTK+ 3.16, see Bassi's blog post.
