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).
