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(). + +.SH "SEE ALSO" +.BR http://doc.trolltech.com/qcontextmenuevent.html +.BR http://www.trolltech.com/faq/tech.html +.SH COPYRIGHT +Copyright 1992-2007 Trolltech ASA, http://www.trolltech.com.
