|
|
|
|
|
|
The TQWSMouseHandler class is a mouse driver for TQt/Embedded.
|
|
<p>
|
|
<p> The mouse driver handles events from system devices and generates
|
|
mouse events.
|
|
<p> A TQWSMouseHandler will usually open some system device in its
|
|
constructor, create a <a href="ntqsocketnotifier.html">TQSocketNotifier</a> on that opened device and
|
|
when it receives data, it will call <a href="#mouseChanged">mouseChanged</a>() to send the
|
|
event to TQt/Embedded for relaying to clients.
|
|
<p>See also <a href="qws.html">TQt/Embedded</a>.

<h3 class=fn><a name="TQWSMouseHandler"></a>TQWSMouseHandler::TQWSMouseHandler ( const <a href="ntqstring.html">TQString</a> & driver = TQString::null, const <a href="ntqstring.html">TQString</a> & device = TQString::null )
|
|
</h3>
|
|
Constructs a mouse handler. This becomes the primary mouse
|
|
handler.
|
|
<p> Note that once created, mouse handlers are controlled by the
|
|
system and should not be deleted.
|
|
<p> The <em>driver</em> and <em>device</em> arguments are not used by this base
|
|
class.
|
|
|
|
<h3 class=fn><a name="~TQWSMouseHandler"></a>TQWSMouseHandler::~TQWSMouseHandler ()<tt> [virtual]</tt>
|
|
</h3>
|
|
Destroys the mouse handler. You should not call this directly.
|
|
|
|
<h3 class=fn>void <a name="calibrate"></a>TQWSMouseHandler::calibrate ( TQWSPointerCalibrationData * )<tt> [virtual]</tt>
|
|
</h3>
|
|
|
|
<p> This method is reimplemented in the calibrated mouse handler to
|
|
set calibration information (from, for instance, the TQtopia
|
|
calibration screen). This version does nothing.
|
|
|
|
<h3 class=fn>void <a name="clearCalibration"></a>TQWSMouseHandler::clearCalibration ()<tt> [virtual]</tt>
|
|
</h3>
|
|
|
|
<p> This method is reimplemented in the calibrated mouse handler to
|
|
clear calibration information. This version does nothing.
|
|
|
|
<h3 class=fn>void <a name="limitToScreen"></a>TQWSMouseHandler::limitToScreen ( <a href="ntqpoint.html">TQPoint</a> & pt )
|
|
</h3>
|
|
Ensures that the given point, <em>pt</em> is within the screen's
|
|
boundaries, changing <em>pt</em> if necessary.
|
|
|
|
<h3 class=fn>void <a name="mouseChanged"></a>TQWSMouseHandler::mouseChanged ( const <a href="ntqpoint.html">TQPoint</a> & pos, int bstate )
|
|
</h3>
|
|
When a mouse event occurs this function is called with the mouse's
|
|
position in <em>pos</em>, and the state of its buttons in <em>bstate</em>.
|
|
|
|
<h3 class=fn>const <a href="ntqpoint.html">TQPoint</a> & <a name="pos"></a>TQWSMouseHandler::pos () const
|
|
</h3>
|
|
|
|
<p> Returns the mouse position.
