Hi, I don't know too much about what you want to do, but in my own
program I can display more than 1 OpenGL widgets simultaneously no
problem. I just put 2 drawing_area widgets inside 2 other different
widgets with the same basic setup. Are you sure you didn't forget to
update them at the same time, or you used the same pointer for both
widgets?

Now for my own problem, I really hope to know how to specify which
OpenGL widget to use with my mouse callback function. Can anyone help
me out?

Best reguards,

Jack
