[Qt-interest] QGraphicsWidget hover events

[Oliver Demetz]

How do you know that the event is never executed?
Hint:
If you just change the visual appearance of your item, be aware that a 
hover-enter or -leave events to not trigger a repaint! I had to call 
this->update() in order to "see" the hover effect!

Oliver
