## 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.

## Member Type Documentation

### enum QGraphicsSceneContextMenuEvent::Reason

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

Constant | Value | Description
--- | --- | ---
`QGraphicsSceneContextMenuEvent::Mouse` | `0` | The mouse caused the event to be sent. On most platforms, this means the right mouse button was clicked.
`QGraphicsSceneContextMenuEvent::Keyboard` | `1` | The keyboard caused this event to be sent. On Windows and Mac OS X, this means the menu button was pressed.
`QGraphicsSceneContextMenuEvent::Other` | `2` | The event was sent by some other means (i.e. not by the mouse or keyboard).
