Hi,

I´m using qt´s ogl widget for my opensg output
(using a PassiveWindow).
It works ok, except for the animated
background. The tutorial provides an
example for glut using something like this:

ViewportPtr vp = gwin->getPort()[0];

and then modifiying the viewport.
gwin is a GLUTWindowPtr. How can I achieve
the same with a passive window?
The getPort Method on my PassiveWindowPtr
seems to return trash.

Cheers,

  Toni
