Hello flood,
you should use connect to a timeout or the idle event an handler which
does somethig similar to the following code. IMO, the idle event is the
better method if you want to burn all the cpu cycle letting you app
goin' to the max speed.
static gboolean timeout (GtkWidget *widget)
{
/* Invalidate the whole window. */
gdk_window_invalidate_rect (widget->window, &widget->allocation, FALSE);
/* Update synchronously. */
gdk_window_process_updates (widget->window, FALSE);
return TRUE;
}
Look at here to see how it is implemented:

Greetings,
Luca

Hello, I'm making a particle system using gtkglext but I have ran
into a problem. Whenever I run my program it only updates the scene
when the window is not in focus. Meaning once a few particles are
drawn it stops updating the window. I have click on another window
and drag it and only than do I see the scene being updated.
My setup is simple:
/* Initialize, Resize, and Render */
g_signal_connect_after (G_OBJECT (gtkinit->drawing_area),
"realize",
G_CALLBACK (InitGL), NULL);
g_signal_connect (G_OBJECT (gtkinit->drawing_area),
"configure_event",
G_CALLBACK (ResizeWin), NULL);
g_signal_connect (G_OBJECT (gtkinit->drawing_area), "expose_event",
G_CALLBACK (DrawScene), NULL);
/* Show the Program */
gtk_container_add(GTK_CONTAINER(winInit.window),
winInit.drawing_area);
gtk_widget_show (winInit.drawing_area);
gtk_widget_show (winInit.window);
gtk_main();
During expose_event I call two functions which update the particles.
