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 QContextMenuEvent::globalPos() is translated into item, scene, and screen coordinates (pos(), scenePos(), and screenPos()).

See also QGraphicsSceneMouseEvent, QGraphicsSceneWheelEvent, and QContextMenuEvent.

Member Type Documentation

enum QGraphicsSceneContextMenuEvent::Reason

This enum describes the reason why the context event was sent.
