[commonqt-devel] Zoom in/out QGraphicsView centering on mouse position

[Rujia Liu]

Problem Solved. My old code only overrides QGraphicsScene's wheel event,
but the default QGraphicsView's wheel event moved the scroll bar before
calling the QGraphicsScene's wheel events, so the behavior messed up :-/

Now I overrided QGraphicsView's wheel event and did not call
(call-next-qmethod event), now it works perfectly!!!
