Detailed Description
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). |
