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 <a href="qpopupmenu.html">QPopupMenu</a> when this event is triggered if you have a relevant context menu. <p> 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. <p> <p>See also <a href="qpopupmenu.html">QPopupMenu</a> and <a href="events.html">Event Classes</a>. <hr><h2>Member Type Documentation</h2> <h3 class=fn><a name="Reason-enum"></a>QContextMenuEvent::Reason</h3> <p> This enum describes the reason the ContextMenuEvent was sent. The values are: <ul> <li><tt>QContextMenuEvent::Mouse</tt> - The mouse caused the event to be sent. Normally this means the right mouse button was clicked, but this is platform specific. <li><tt>QContextMenuEvent::Keyboard</tt> - The keyboard caused this event to be sent. On windows this means the menu button was pressed. <li><tt>QContextMenuEvent::Other</tt> - The event was sent by some other means (i.e. not by the mouse or keyboard). </ul> <hr><h2>Member Function Documentation</h2> <h3 class=fn><a name="QContextMenuEvent"></a>QContextMenuEvent::QContextMenuEvent ( <a href="qcontextmenuevent.html#Reason-enum">Reason</a> reason, const <a href="qpoint.html">QPoint</a> & pos, const <a href="qpoint.html">QPoint</a> & globalPos, int state ) </h3> <p> Constructs a context event object with the accept parameter flag set to FALSE. <p> The <em>reason</em> parameter must be <a href="#Reason-enum">QContextMenuEvent::Mouse</a> or <a href="#Reason-enum">QContextMenuEvent::Keyboard</a>. <p> The <em>pos</em> parameter specifies the mouse position relative to the receiving widget. <em>globalPos</em> is the mouse position in absolute coordinates. <em>state</em> is the ButtonState at the time of the event. <h3 class=fn><a name="QContextMenuEvent-2"></a>QContextMenuEvent::QContextMenuEvent ( <a href="qcontextmenuevent.html#Reason-enum">Reason</a> reason, const <a href="qpoint.html">QPoint</a> & pos, int state ) </h3> <p> Constructs a context event object with the accept parameter flag set to FALSE. <p> The <em>reason</em> parameter must be <a href="#Reason-enum">QContextMenuEvent::Mouse</a> or <a href="#Reason-enum">QContextMenuEvent::Keyboard</a>. <p> The <em>pos</em> parameter specifies the mouse position relative to the receiving widget. <em>state</em> is the ButtonState at the time of the event. <p> The <a href="#globalPos">globalPos</a>() is initialized to <a href="qcursor.html#pos">QCursor::pos</a>(), which may not be appropriate. Use the other constructor to specify the global position explicitly. <h3 class=fn>void <a name="accept"></a>QContextMenuEvent::accept () </h3> Sets the accept flag of the context event object. <p> 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 <a href="#consume">consume</a>(). <p> The accept flag is not set by default. <p> <p>See also <a href="#ignore">ignore</a>() and <a href="#consume">consume</a>(). <h3 class=fn>void <a name="consume"></a>QContextMenuEvent::consume () </h3> Sets the consume flag of the context event object. <p> Setting the consume flag indicates that the receiver of this event asked that the event not be propagated further (to parent classes). <p> The consumed flag is not set by default. <p> <p>See also <a href="#ignore">ignore</a>() and <a href="#accept">accept</a>(). <h3 class=fn>const <a href="qpoint.html">QPoint</a> & <a name="globalPos"></a>QContextMenuEvent::globalPos () const </h3> <p> Returns the global position of the mouse pointer at the time of the event. <p> <p>See also <a href="#x">x</a>(), <a href="#y">y</a>() and <a href="#pos">pos</a>(). <h3 class=fn>int <a name="globalX"></a>QContextMenuEvent::globalX () const </h3> <p> Returns the global X position of the mouse pointer at the time of the event. <p>See also <a href="#globalY">globalY</a>() and <a href="#globalPos">globalPos</a>(). <h3 class=fn>int <a name="globalY"></a>QContextMenuEvent::globalY () const </h3> <p> Returns the global Y position of the mouse pointer at the time of the event. <p>See also <a href="#globalX">globalX</a>() and <a href="#globalPos">globalPos</a>(). <h3 class=fn>void <a name="ignore"></a>QContextMenuEvent::ignore () </h3> Clears the accept flag of the context event object. <p> Clearing the accept flag indicates that the receiver of this event does not need to show a context menu.
