However, the correct solution is to use one of the two dedicated functions in QGraphicsView
that allow you to paint behind all items in the background, or as overlay on top of all items:
virtual void drawBackground ( QPainter * painter, const QRectF & rect )
virtual void drawForeground ( QPainter * painter, const QRectF & rect )

However, the correct solution is to use one of the two dedicated functions in QGraphicsView

virtual void drawBackground ( QPainter * painter, const QRectF & rect )
virtual void drawForeground ( QPainter * painter, const QRectF & rect )
