How to detect QT Mouse events outside a application window?

[Danie]

I am stuck badly in this...
I cannot implement simultaneous mouse events in 2 separate class (as per above solution) as I don't which one will be fired first and how to then inform the second mouse event one about it.
I have a QGraphicsSceneMouseEvent running for a QGraphicsScene inside QGraphicsView. So I want to determine when a mouse event (from QGraphicsSceneMouseEvent) runs outside a QApplication window.
Isn't their any direct function call API for this determining whether the mouse move event goes outside app window?

Yes. QWidget::leaveEvent()
