+.SH DESCRIPTION
+The QContextMenuEvent class contains parameters that describe a context menu event.
+.PP
+Context menu events are sent to widgets when a user triggers a context menu. What triggers this is platform dependent. For example, on Windows, pressing the menu button or releasing the right mouse button will cause this event to be sent.
+.PP
+When this event occurs it is customary to show a QPopupMenu with a context menu, if this is relevant to the context.
+.PP
+Context menu events contain a special accept flag that indicates whether the receiver accepted the event. If the event handler does not accept the event, then whatever triggered the event will be handled as a regular input event if possible.
+.PP
+See also QPopupMenu and Event Classes.
+.SS "Member Type Documentation"
+.SH "QContextMenuEvent::Reason"
+This enum describes the reason the ContextMenuEvent was sent. The values are:
+.TP
+\fCQContextMenuEvent::Mouse\fR - The mouse caused the event to be sent. Normally this means the right mouse button was clicked, but this is platform specific.
+.TP
+\fCQContextMenuEvent::Keyboard\fR - The keyboard caused this event to be sent. On Windows this means the menu button was pressed.
+.TP
+\fCQContextMenuEvent::Other\fR - The event was sent by some other means (i.e. not by the mouse or keyboard).
+.SH MEMBER FUNCTION DOCUMENTATION
+.SH "QContextMenuEvent::QContextMenuEvent ( Reason reason, const QPoint & pos, const QPoint & globalPos, int state )"
+Constructs a context menu event object with the accept parameter flag set to FALSE.
+.PP
+The \fIreason\fR parameter must be QContextMenuEvent::Mouse or QContextMenuEvent::Keyboard.
+.PP
+The \fIpos\fR parameter specifies the mouse position relative to the receiving widget. \fIglobalPos\fR is the mouse position in absolute coordinates. \fIstate\fR is the ButtonState at the time of the event.
+.SH "QContextMenuEvent::QContextMenuEvent ( Reason reason, const QPoint & pos, int state )"
+Constructs a context menu event object with the accept parameter flag set to FALSE.
+.PP
+The \fIreason\fR parameter must be QContextMenuEvent::Mouse or QContextMenuEvent::Keyboard.
+.PP
+The \fIpos\fR parameter specifies the mouse position relative to the receiving widget. \fIstate\fR is the ButtonState at the time of the event.
+.PP
+The globalPos() is initialized to QCursor::pos(), which may not be appropriate. Use the other constructor to specify the global position explicitly.
+.SH "void QContextMenuEvent::accept ()"
+Sets the accept flag of the context event object.
+.PP
+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 consumed.
+.PP
+The accept flag is not set by default.
+.PP
+See also ignore() and consume().
+.SH "void QContextMenuEvent::consume ()"
+Sets the consume flag of the context event object.
+.PP
+Setting the consume flag indicates that the receiver of this event does not want the event to be propagated further (i.e. not sent to parent classes.)
+.PP
+The consumed flag is not set by default.
+.PP
+See also ignore() and accept().
+.SH "const QPoint & QContextMenuEvent::globalPos () const"
+Returns the global position of the mouse pointer at the time of the event.
+.PP
+See also x(), y(), and pos().
+.SH "int QContextMenuEvent::globalX () const"
+Returns the global x-position of the mouse pointer at the time of the event.
+.PP
+See also globalY() and globalPos().
+.SH "int QContextMenuEvent::globalY () const"
+Returns the global y-position of the mouse pointer at the time of the event.
+.PP
+See also globalX() and globalPos().
+.SH "void QContextMenuEvent::ignore ()"
+Clears the accept flag of the context event object.
+.PP
+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.
+.PP
+The accept flag is not set by default.
+.PP
+See also accept() and consume().
+.SH "bool QContextMenuEvent::isAccepted () const"
+Returns TRUE if the receiver has processed the event; otherwise returns FALSE.
+.PP
+See also accept(), ignore(), and consume().
+.SH "bool QContextMenuEvent::isConsumed () const"
+Returns TRUE (which stops propagation of the event) if the receiver has blocked the event; otherwise returns FALSE.
+.PP
+See also accept(), ignore(), and consume().
+.SH "const QPoint & QContextMenuEvent::pos () const"
+Returns the position of the mouse pointer relative to the widget that received the event.
+.PP
+See also x(), y(), and globalPos().
+.SH "Reason QContextMenuEvent::reason () const"
+Returns the reason for this context event.
+.SH "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.
+.PP
+The returned value is LeftButton, RightButton, MidButton, ShiftButton, ControlButton and AltButton OR'ed together.
+.SH "int QContextMenuEvent::x () const"
+Returns the x-position of the mouse pointer, relative to the widget that received the event.
+.PP
+See also y() and pos().
+.SH "int QContextMenuEvent::y () const"
+Returns the y-position of the mouse pointer, relative to the widget that received the event.
+.PP
+See also x() and pos().
