What triggers this is platform dependent. Forexample, on Windows, pressing the menu button or releasing theright mouse button will cause this event to be sent.<p> When this event occurs it is customary to show a <a href="qpopupmenu.html">QPopupMenu</a> with acontext menu, if this is relevant to the context.<p> Context menu events contain a special accept flag that indicateswhether the receiver accepted the event. If the event handler doesnot accept the event, then whatever triggered the event will behandled 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. Thevalues are:<ul><li><tt>QContextMenuEvent::Mouse</tt> - The mouse caused the event to be sent. Normally thismeans the right mouse button was clicked, but this is platformspecific.<li><tt>QContextMenuEvent::Keyboard</tt> - The keyboard caused this event to be sent. OnWindows this means the menu button was pressed.<li><tt>QContextMenuEvent::Other</tt> - The event was sent by some other means (i.e. not bythe 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 menu event object with the accept parameterflag 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 thereceiving widget. <em>globalPos</em> is the mouse position in absolutecoordinates. <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 menu event object with the accept parameterflag 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 thereceiving widget. <em>state</em> is the ButtonState at the time of theevent.<p> The <a href="#globalPos">globalPos</a>() is initialized to <a href="qcursor.html#pos">QCursor::pos</a>(), which may not beappropriate.
