    28     When widget need to use horizontal pan gesture itself, e.g when slider is used

    29     it must implement bool isPannable(QGraphicsMouseEvent *)  function. 

    30     

    31     Home Screen will call this when it recognize a pan gesture on a widget. 

    32     By default, horizontal pan gesture is used to switch pages, but if isPannable() 

    33     returns true, event is not filtered by Home Screen.
