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()).

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 macOS, 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).
