    \brief Class showing a widget as popup window.
 
    setWidget() function allows you to specify the widget to be popped up.
    After widget is set, you normally should call show() slot in order to pop the
    widget up at the specified global position.
 
    VWidgetPopup takes care about positioning of your widget on the screen so it will
    be always visible even if popped beside.
