Detailed Description

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 Type Documentation

 

enum QContextMenuEvent::Reason

This enum describes the reason why the event was sent.

Constant

Value

Description

QContextMenuEvent::Mouse

0

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

QContextMenuEvent::Keyboard

1

The keyboard caused this event to be sent. On Windows, this means the menu button was pressed.

QContextMenuEvent::Other

2

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

Member Function Documentation

 

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

Obsolete Members for QContextMenuEvent

The following members of class QContextMenuEvent are deprecated. We strongly advise against using them in new code.

Obsolete Member Function Documentation

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

This function is deprecated since 6.4. We strongly advise against using it in new code.

Use the other constructor instead (global position is required).

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.
