Hello,

I'm trying to intercept wheel events in an event filter and it's not working. Here is the filter:

Qt Code: 
  1. bool KeyframeArea::eventFilter(QObject *obj, QEvent *event)
  2. {
  3. 	if (event->type() == QEvent::MouseButtonPress)
  4. 	{
  5. 		QMouseEvent *mouseEvent = static_cast<QMouseEvent *> (event);
  6. 		mousePressEvent(mouseEvent);
  7. 		return true;
  8. 	}
  9. 	else if (event->type() == QEvent::MouseButtonRelease)
  10. 	{
  11. 		QMouseEvent *mouseEvent = static_cast<QMouseEvent *> (event);
  12. 		mouseReleaseEvent(mouseEvent);
  13. 		return true;
  14. 	}
  15. 	else if (event->type() == QEvent::Wheel)
  16. 	{
  17. 		QWheelEvent *wheelEvent = static_cast<QWheelEvent *> (event);
  18. 		wheelEvent(wheelEvent);
  19. 		return true;
  20. 	}
  21.  
  22. 	// Continue standard event processing.
  23. 	return QObject::eventFilter(obj, event);
  24. }

The filter works for button press and release. For the wheelEvent call I get the error message: `wheelEvent' cannot be used as a function. What's wrong with this? QWheelEvent is included and void wheelEvent(QWheelEvent* event) is declared.
