DESCRIPTION
The QContextMenuEvent class contains parameters that describe a context menu event.

Context events are sent to widgets when a user triggers a menu. What triggers this is platform dependent. On windows, for example, pressing the menu button or releasing the right mouse button will cause this event to be sent. It is customary to use this to show a QPopupMenu when this event is triggered if you have a relevant context menu.

ContextMenu events contain a special accept flag that indicates whether the receiver accepted the contextMenu. If the event handler does not accept the event, then whatever triggered the event will be handled as a regular input event if possible.

See also QPopupMenu and Event Classes.

  Member Type Documentation

QContextMenuEvent::Reason
This enum describes the reason the ContextMenuEvent was sent. The values are:

QContextMenuEvent::Mouse - The mouse caused the event to be sent. Normally this means the right mouse button was clicked, but this is platform specific.

QContextMenuEvent::Keyboard - The keyboard caused this event to be sent. On windows this means the menu button was pressed.

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

MEMBER FUNCTION DOCUMENTATION

QContextMenuEvent::QContextMenuEvent ( Reason reason, const QPoint & pos, const QPoint & globalPos, int state )
Constructs a context 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. state is the ButtonState at the time of the event.

QContextMenuEvent::QContextMenuEvent ( Reason reason, const QPoint & pos, int state )
Constructs a context 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. state is the ButtonState at the time of the event.

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

void QContextMenuEvent::accept ()
Sets the accept flag of the context event object.

Setting the accept flag indicates that the receiver of this event has processed the event. Processing the event means you did something with it and it will be implicitly consume().

The accept flag is not set by default.

See also ignore() and consume().

void QContextMenuEvent::consume ()
Sets the consume flag of the context event object.

Setting the consume flag indicates that the receiver of this event asked that the event not be propagated further (to parent classes).

The consumed flag is not set by default.

See also ignore() and accept().

const QPoint & QContextMenuEvent::globalPos () const
Returns the global position of the mouse pointer at the time of the event.

See also x(), y() and pos().

int QContextMenuEvent::globalX () const
Returns the global X position of the mouse pointer at the time of the event.

See also globalY() and globalPos().

int QContextMenuEvent::globalY () const
Returns the global Y position of the mouse pointer at the time of the event.

See also globalX() and globalPos().

void QContextMenuEvent::ignore ()
Clears the accept flag of the context event object.

Clearing the accept flag indicates that the receiver of this event does not need to show a context menu. This will implicitly remove the consumed flag as well.

The accept flag is not set by default.

See also accept() and consume().

bool QContextMenuEvent::isAccepted () const
Returns TRUE if the receiver has processed the event; otherwise returns FALSE.

See also accept(), ignore() and consume().

bool QContextMenuEvent::isConsumed () const
Returns TRUE (which stops propagation of the event) if the receiver has blocked the event; otherwise returns FALSE.

See also accept(), ignore() and consume().

const QPoint & QContextMenuEvent::pos () const
Returns the position of the mouse pointer relative to the widget that received the event.

See also x(), y() and globalPos().

Reason QContextMenuEvent::reason () const
Returns the reason for this context event.

ButtonState QContextMenuEvent::state () const
Returns the button state (a combination of mouse buttons and keyboard modifiers), i.e., what buttons and keys were being pressed immediately before the event was generated.

The returned value is LeftButton, RightButton, MidButton, ShiftButton, ControlButton and AltButton OR'ed together.

int QContextMenuEvent::x () const
Returns the X position of the mouse pointer, relative to the widget that received the event.

See also y() and pos().

int QContextMenuEvent::y () const
Returns the Y position of the mouse pointer, relative to the widget that received the event.

See also x() and pos().
