Overloading QGraphicsView function from Qt Designer

[norobro]

QGraphicsView::wheelEvent() is not a signal so there is nothing to connect. What you want to do is override wheelEvent() not overload it.

I've just dabbled in Python so I'm not sure this is correct, but at the bottom of your mainWindow class add the following and delete the "self.connect" statement:

// added this line so next line would indent
        self.nodeDropGraphicsView.wheelEvent = self.wheelEvent
 
    def wheelEvent(self,  event):
        print("wheel event")

// added this line so next line would indent
        self.nodeDropGraphicsView.wheelEvent = self.wheelEvent

    def wheelEvent(self,  event):
        print("wheel event")
