Disable QListView scroll event

I have QTreeView and every second row QListView with items. Now I can't scroll QTreeView because QTListView is taking the event over.
Is it possible to disable the scrolling on the list ??

have a CuctomListView and then ignore the mouse scroll event, so that is passed on to the parent widget

Code:

---

void CuctomListView::wheelEvent(QWheelEvent* event) //virtual protected in QWidget
{
    event->ignore();
}
