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. <!-- eof --> <hr><p> This file is part of the <a href="index.html">Qt toolkit</a>.
