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.

ConstantValueDescription

QGraphicsSceneContextMenuEvent::Keyboard1The keyboard caused this event to be sent. On Windows and Mac OS X, this means the menu button was pressed.
QGraphicsSceneContextMenuEvent::Other2The event was sent by some other means (i.e. not by the mouse or keyboard).
