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.

QGraphicsSceneContextMenuEvent::Other2The event was sent by some other means (i.e. not by the mouse or keyboard).
