Hi,
Is there a way to ensure that a redisplay occurs?
Here's an example situation: I let the user change the
background color. A pop up window appears and
the user selects the new color. The window disappears
and then I change the background color and call
glutPostRedisplay(). Unfortunately, the background
color doesn't change right away.
It only occurs (I don't know why) when the user
clicks in the OpenGL window.
Thanks.
