[Qt-interest] need to define mousePressEvent to make mouseMoveEvent work?????

[Yifei Li]

Hi,

I noticed this recently:

I add a custome widget to QGraphicsScene and implemented mouseMoveEvent for the custome QWidget class.

However, I need to define mousePressEvent(even its body is EMPTY) for mouseMoveEvent to work. Otherwise, my custome QWidget would not receive mouse move event.

Could someone tell me why is that?

Thanks
