<hr><a name="details"></a><h2>Detailed Description</h2>


The TQContextMenuEvent class contains parameters that describe a context menu event.
<p> 
<p> 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.
<p> When this event occurs it is customary to show a <a href="ntqpopupmenu.html">TQPopupMenu</a> with a
context menu, if this is relevant to the context.
<p> 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.
<p> <p>See also <a href="ntqpopupmenu.html">TQPopupMenu</a> and <a href="events.html">Event Classes</a>.

<hr><h2>Member Type Documentation</h2>
<h3 class=fn><a name="Reason-enum"></a>TQContextMenuEvent::Reason</h3>

<p> This enum describes the reason the ContextMenuEvent was sent. The
values are:
<ul>
<li><tt>TQContextMenuEvent::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>TQContextMenuEvent::Keyboard</tt> - The keyboard caused this event to be sent. On
Windows this means the menu button was pressed.
<li><tt>TQContextMenuEvent::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="TQContextMenuEvent"></a>TQContextMenuEvent::TQContextMenuEvent ( <a href="qcontextmenuevent.html#Reason-enum">Reason</a>&nbsp;reason, const&nbsp;<a href="ntqpoint.html">TQPoint</a>&nbsp;&amp;&nbsp;pos, const&nbsp;<a href="ntqpoint.html">TQPoint</a>&nbsp;&amp;&nbsp;globalPos, int&nbsp;state )
</h3>

<p> Constructs a context menu event object with the accept parameter
flag set to FALSE.
<p> The <em>reason</em> parameter must be <a href="#Reason-enum">TQContextMenuEvent::Mouse</a> or <a href="#Reason-enum">TQContextMenuEvent::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="TQContextMenuEvent-2"></a>TQContextMenuEvent::TQContextMenuEvent ( <a href="qcontextmenuevent.html#Reason-enum">Reason</a>&nbsp;reason, const&nbsp;<a href="ntqpoint.html">TQPoint</a>&nbsp;&amp;&nbsp;pos, int&nbsp;state )
</h3>

<p> Constructs a context menu event object with the accept parameter
flag set to FALSE.
<p> The <em>reason</em> parameter must be <a href="#Reason-enum">TQContextMenuEvent::Mouse</a> or <a href="#Reason-enum">TQContextMenuEvent::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="ntqcursor.html#pos">TQCursor::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>TQContextMenuEvent::accept ()
</h3>

<p> 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 consumed.
<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>TQContextMenuEvent::consume ()
</h3>

<p> Sets the consume flag of the context event object.
<p> 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.)
<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&nbsp;<a href="ntqpoint.html">TQPoint</a>&nbsp;&amp; <a name="globalPos"></a>TQContextMenuEvent::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>TQContextMenuEvent::globalX () const
</h3>

<p> Returns the global x-position of the mouse pointer at the time of
the event.
<p> <p>See also <a href="#globalY">globalY</a>() and <a href="#globalPos">globalPos</a>().

<h3 class=fn>int <a name="globalY"></a>TQContextMenuEvent::globalY () const
</h3>

<p> Returns the global y-position of the mouse pointer at the time of
the event.
<p> <p>See also <a href="#globalX">globalX</a>() and <a href="#globalPos">globalPos</a>().

<h3 class=fn>void <a name="ignore"></a>TQContextMenuEvent::ignore ()
</h3>

<p> 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. This will implicitly remove
the consumed flag as well.
<p> The accept flag is not set by default.
<p> <p>See also <a href="#accept">accept</a>() and <a href="#consume">consume</a>().

<h3 class=fn>bool <a name="isAccepted"></a>TQContextMenuEvent::isAccepted () const
</h3>

<p> Returns TRUE if the receiver has processed the event; otherwise
returns FALSE.
<p> <p>See also <a href="#accept">accept</a>(), <a href="#ignore">ignore</a>(), and <a href="#consume">consume</a>().

<h3 class=fn>bool <a name="isConsumed"></a>TQContextMenuEvent::isConsumed () const
</h3>

<p> Returns TRUE (which stops propagation of the event) if the
receiver has blocked the event; otherwise returns FALSE.
<p> <p>See also <a href="#accept">accept</a>(), <a href="#ignore">ignore</a>(), and <a href="#consume">consume</a>().

<h3 class=fn>const&nbsp;<a href="ntqpoint.html">TQPoint</a>&nbsp;&amp; <a name="pos"></a>TQContextMenuEvent::pos () const
</h3>

<p> Returns the position of the mouse pointer relative to the widget
that received the event.
<p> <p>See also <a href="#x">x</a>(), <a href="#y">y</a>(), and <a href="#globalPos">globalPos</a>().

<h3 class=fn><a href="qcontextmenuevent.html#Reason-enum">Reason</a> <a name="reason"></a>TQContextMenuEvent::reason () const
</h3>

<p> Returns the reason for this context event.

<h3 class=fn><a href="ntqt.html#ButtonState-enum">ButtonState</a> <a name="state"></a>TQContextMenuEvent::state () const
</h3>

<p> 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.
<p> The returned value is <a href="ntqt.html#ButtonState-enum">LeftButton</a>, <a href="ntqt.html#ButtonState-enum">RightButton</a>, <a href="ntqt.html#ButtonState-enum">MidButton</a>,
<a href="ntqt.html#ButtonState-enum">ShiftButton</a>, <a href="ntqt.html#ButtonState-enum">ControlButton</a> and <a href="ntqt.html#ButtonState-enum">AltButton</a> OR'ed together.

<h3 class=fn>int <a name="x"></a>TQContextMenuEvent::x () const
</h3>

<p> Returns the x-position of the mouse pointer, relative to the
widget that received the event.
<p> <p>See also <a href="#y">y</a>() and <a href="#pos">pos</a>().

<h3 class=fn>int <a name="y"></a>TQContextMenuEvent::y () const
</h3>

<p> Returns the y-position of the mouse pointer, relative to the
widget that received the event.
<p> <p>See also <a href="#x">x</a>() and <a href="#pos">pos</a>().
