[vtkusers] Re : Enable/Disable Offscreen rendering

[Clinton Stimpson]

To take a snapshot of the app, QPixmap::grabWidget() is supposed to work.  
Have you tried that?
QVTKWidget will take the onscreen pixels and put it in that QPixmap, while the 
other QWidgets will paint themselves into the QPixmap.
If you want to use offscreen, I suppose you could set the offscreen flag, then 
still call QPixmap::grabWidget().
