Detailed Description

The QContextMenuEvent class contains parameters that describe a context menu event. \inmodule QtGui.

Context menu events are sent to widgets when a user performs an action associated with opening a context menu. The actions required to open context menus vary between platforms; for example, on Windows, pressing the menu button or clicking the right mouse button will cause this event to be sent.

When this event occurs it is customary to show a QMenu with a context menu, if this is relevant to the context.

Member Enumeration Documentation

◆ Reason

enum QContextMenuEvent::Reason

This enum describes the reason why the event was sent.

\value Mouse The mouse caused the event to be sent. Normally this means the right mouse button was clicked, but this is platform dependent.

\value Keyboard The keyboard caused this event to be sent. On Windows, 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).

Constructor & Destructor Documentation

◆ QContextMenuEvent() [1/2]

QContextMenuEvent::QContextMenuEvent	(	Reason	reason,
		const QPoint &	pos,
		const QPoint &	globalPos,
		Qt::KeyboardModifiers	modifiers = `Qt::NoModifier`
	)

Constructs a context menu event object with the accept parameter flag set to false.

The reason parameter must be QContextMenuEvent::Mouse or QContextMenuEvent::Keyboard.

The pos parameter specifies the mouse position relative to the receiving widget. globalPos is the mouse position in absolute coordinates. The modifiers holds the keyboard modifiers.

Definition at line 2007 of file qevent.cpp.

◆ QContextMenuEvent() [2/2]

QContextMenuEvent::QContextMenuEvent	(	Reason	reason,
		const QPoint &	pos
	)

Constructs a context menu event object with the accept parameter flag set to false.

The reason parameter must be QContextMenuEvent::Mouse or QContextMenuEvent::Keyboard.

The pos parameter specifies the mouse position relative to the receiving widget.

The globalPos() is initialized to QCursor::pos(), which may not be appropriate. Use the other constructor to specify the global position explicitly.
