Detailed Description

The QGraphicsSceneContextMenuEvent class provides context menu events in the graphics view framework.

Since

4.2

\inmodule QtWidgets

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 Enumeration Documentation

Reason

enum QGraphicsSceneContextMenuEvent::Reason

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

\value Mouse The mouse caused the event to be sent. On most platforms, this means the right mouse button was clicked.

\value Keyboard The keyboard caused this event to be sent. On Windows and \macos, this means the menu button was pressed.

\value Other The event was sent by some other means (i.e. not by the mouse or keyboard).
