Re: [GtkGLExt] OpenGL rendering context - multithreading

[Jose Commins <axora axora net>]

   It depends on the render ordering and making sure the widget is 
configured properly at the right place.

   You should assume that most OpenGL drivers aren't thread-aware, 
which is why one has to be careful on the ordering sequence of 
GL-related commands.  Also, if you are using a (non-timer) thread that 
isn't managed by GTK to render, you should lock it or make GTK aware 
that you are going to fiddle with parameters using 'gdk_threads_enter 
()' etc to signal you are sending commands outside GDK.

   I have put up an example of this type of thing on Sourceforge:
