* \brief This class contains event parameters for orientation change events.
*
* The orientation change event occurs whenever the viewport changes its
* orientation between landscape and portrait (note that it doesn't occur
* when changing angle e.g. from 0 directly to 180 degrees). It is also sent to MApplicationPage
* when it is about to be shown for the first time - MApplicationPage::appear().
*
* It is used to notify widgets about the orientation change. It can be asked
* about the new orientation of the viewport. You can handle this event
* either by catching it in QGraphicsItem::event() or reimplementing
* MWidget::orientationChangeEvent().
*
* \sa MWidget::orientationChangeEvent()
