Hi,

I have two windows which I display as fullscreen on my two computer screens. One is a gui and one is a QGLWidget object. The problem I'm having is that when I click on the gui window, the contents of the gl window are redrawn (i.e. the screen flashes and I can see each object in the scene graph being redrawn). Therefore, if I click on a button on the gui, there is a half second delay while it waits for the screen to redraw. The sceen is also redraw when the gl window recieves focus again. While the gl screen has focus, I can navigate through it without any problems and there is no such redrawing.

What can I do to ensure that the whole window isn't redraw as described when it loses and gains focus?

Thanks for your help,

Barry.
