Detailed Description
The QGraphicsSceneContextMenuEvent class provides context menu events in the graphics view framework.
A QContextMenuEvent received by a QGraphicsView is translated into a QGraphicsSceneContextMenuEvent. The QWheelEvent::globalPos() is translated into item, scene, and screen coordinates (pos(), scenePos(), and screenPos()).
See also QGraphicsSceneMouseEvent, QGraphicsSceneWheelEvent, and QContextMenuEvent.
