    When widget need to use horizontal pan gesture itself, e.g when slider is used
    it must implement bool isPannable(QGraphicsMouseEvent *)  function. 
    
    Home Screen will call this when it recognize a pan gesture on a widget. 
    By default, horizontal pan gesture is used to switch pages, but if isPannable() 
    returns true, event is not filtered by Home Screen.
