The docs for QGraphicsView explain how to "provide your own custom scene 
interaction."  If the QVTKWidget2 is your viewport widget, and you want it to 
get those events, that falls under custom scene interaction.  By default the 
events are passed through the QGraphicsScene and onto the QGraphicsItems.
