:) In fact I based my comment on that article, I thought QMouseEvent 
inherites from QEvent and QInputEvent because in QT docs it says:
"1 public function inherited from QInputEvent
6 public functions inherited from QEvent"
As I didn't look at the source to find from what class it inherits first, I 
though that QEvent was more logical from the name, I see I was wrong :)

And, what about the other part.  Storing custom data in QWidget, any idea?
