adding QGraphicsItem to multiple scenes

[wysota]

So my problem has been, if I use only one scene and I add approx 20 QGraphicsItemGroup's to it. How can I make it so that I only show one of the QGraphicsItemGroup's in graphicsView2, using only 1 scene?

I think you can use QGraphicsView::setSceneRect() to ask the view to only visualise a rectangle occupied by a single group.
