[GtkGLExt] Suitability for real-time apps (i.e. Gamezzz)

[Asfand Yar Qazi <email asfandyar cjb net>]

Hi,

What is the feasibility of using Gtkglext for games?  By this I mean, I want 
full control over the application loop and don't want GTK to take it over, and 
I want to be able to push as much information into the graphics card as 
possible, and I want double-buffered fullscreen.

Is this possible with Gtkglext?  Is GTK+ capable of functioning in a 
'secondary' capacity to someone elses main() function, so to speak?

Has it been done before?  I'm thinking of using OpenSceneGraph for this 
purpose (which doesn't do any window system specific stuff, just handles OpenGL)

Also, I may need 'out-of-the-way' mouse/joystick/keyboard handling, and I'm 
thinking of using SDL for this - feasible?

Thanks
