    Default Re: QWheelEvent not working in event(QEvent*e) reimplementation

    Hello

    I am trying to catch the wheel event of my QGraphicsView subclass and for this I am reimplementing the event() method. When I do :

    Qt Code:
    1. bool GraphicsView::event(QEvent* event)
    2. {
    3.  
    4. if(event->type() == QEvent::Wheel){
    5. qDebug("ENTERED")
    6. return false;
    7. }
    8.  
    9. return QGraphicsView::event(event);
    10.  
    11. }
    To copy to clipboard, switch view to plain text mode 

    This is just to test and I noticed that when I move the wheel the if statement never gets accessed. What is the proper way to say "if the event is a mouse wheel event" to be able to implement what I need inside the if statement??

    Thanks.


    Added after 24 minutes:


    Found the problem, since I already also had an implementation of the wheelEvent in my QGV class I just forgot to call the super class in my implementation.
    Adding QGraphicsView::wheelEvent() made the above work as expected

    Why not just reimplement wheelEvent in the first place?
