<hr><a name="details"></a><h2>Detailed Description</h2>
The QWSMouseHandler class is a mouse driver for Qt/Embedded.
<p>
<p> The mouse driver handles events from system devices and generates
mouse events.
<p> A QWSMouseHandler will usually open some system device in its
constructor, create a <a href="qsocketnotifier.html">QSocketNotifier</a> on that opened device and
when it receives data, it will call <a href="#mouseChanged">mouseChanged</a>() to send the
event to Qt/Embedded for relaying to clients.
<p>See also <a href="qws.html">Qt/Embedded</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QWSMouseHandler"></a>QWSMouseHandler::QWSMouseHandler ( const <a href="qstring.html">QString</a> & driver = QString::null, const <a href="qstring.html">QString</a> & device = QString::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="~QWSMouseHandler"></a>QWSMouseHandler::~QWSMouseHandler ()<tt> [virtual]</tt>
</h3>
Destroys the mouse handler. You should not call this directly.
<h3 class=fn>void <a name="calibrate"></a>QWSMouseHandler::calibrate ( QWSPointerCalibrationData * )<tt> [virtual]</tt>
</h3>
<p> This method is reimplemented in the calibrated mouse handler to
set calibration information (from, for instance, the Qtopia
calibration screen). This version does nothing.
<h3 class=fn>void <a name="clearCalibration"></a>QWSMouseHandler::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>QWSMouseHandler::limitToScreen ( <a href="qpoint.html">QPoint</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>QWSMouseHandler::mouseChanged ( const <a href="qpoint.html">QPoint</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="qpoint.html">QPoint</a> & <a name="pos"></a>QWSMouseHandler::pos () const
</h3>
<p> Returns the mouse position.
