    \class HbEvent
    \brief HbEvent is a class having support for Hb specific events.

    This class supports following extra types of events besides those supported by QEvent


    ChildFocusIn - This event is sent from child widget to parent widget to notify that the child 
                   has got the focus. Normally the parent may show some visualization 
                   change when its child gets focus.

    ChildFocusOut - This event is sent from child widget to parent widget to notify that the child 
                   has lost the focus. Normally the parent may show some visualization 
                   change when its child gets focus.

    ThemeChanged - This event is sent to all QGraphicsWidget. The widget can handle this event by 
                   implementing changeEvent() virtual function.

    DeviceProfileChanged - This event is sent by the system when device's device profile 
                  (screen resolution) changes. The event causes automatic polish call and 
                  the event can be catched in event(QEvent *event) method.

    SleepModeEnter - This event is sent by the system when the phone enters to the sleep mode. 
                     If your application/component needs to take some action when entering the
                     sleep mode then you can do it in event(QEvent *event) method.
    
    SleepModeExit - This event is sent by the system when the phone exist from the sleep mode.
                    If your application/component needs to take some action when exiting the
                    sleep mode then you can do it in event(QEvent *event) method.

    DeviceProfileChanged - This event is sent by the system when layout direction of the main
                           window changes. If your application/component needs to take some
                           action upon this event you can do it in event(QEvent *event) method.
