Hi all,
I have a widget (OpArea) that reimplements QWidget's wheelEvent handler. The parent of this widget is a scrollArea. I need the wheelEvent of OpArea to be called and under certain circumstances (no Alt modifier) the event needs to be propagated to the parent, to scroll the window.

Qt Code: 
  1. void OpArea::wheelEvent(QWheelEvent *event)
  2. {
  3. 	if(event->modifiers() == Qt::AltModifier)
  4. 	{
  5. 		//handle the event in OpArea
  6. 		static int theta = 0;
  7. 		if (event->delta()>=0)
  8. 		{
  9. 			 theta= theta +20;
  10. 		}
  11. 		else
  12. 			theta = theta -20;
  13.  
  14. 		if (theta <0) 
  15. 			theta = 340;
  16. 		if (theta> 340)
  17. 			theta = 0;
  18. 		cout << theta <<endl;
  19. 	}
  20. 	else
  21. 	{
  22. 		//send to parent's wheelEvent...		
  23. 	}
  24.  
  25. }

I think i should be using QApplication::notify() or maybe postEvent() but I am not sure exactly how.... I would appreciate any ideas, thanks
