.SH DESCRIPTION
The QWSMouseHandler class is a mouse driver/handler for Qt/Embedded.
.PP
The mouse driver/handler handles events from system devices and generates mouse events.
.PP
A QWSMouseHandler will usually open some system device in its constructor, create a QSocketNotifier on that opened device and when it receives data, it will call mouseChanged() to send the event to Qt/Embedded for relaying to clients.
.PP
See also Qt/Embedded.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QWSMouseHandler::QWSMouseHandler ()"
Constructs a mouse handler. This becomes the primary mouse handler.
.PP
Note that once created, mouse handlers are controlled by the system and should not be deleted.
.SH "QWSMouseHandler::~QWSMouseHandler ()\fC [virtual]\fR"
Destroys the mouse handler. You should not call this directly.
.SH "void QWSMouseHandler::calibrate ( QWSPointerCalibrationData * )\fC [virtual]\fR"
This method is reimplemented in the calibrated mouse handler to set calibration information (from, for instance, the QPE calibration screen). This version does nothing.
.SH "void QWSMouseHandler::clearCalibration ()\fC [virtual]\fR"
This method is reimplemented in the calibrated mouse handler to clear calibration information. This version does nothing.
.SH "void QWSMouseHandler::mouseChanged ( const QPoint & pos, int bstate )\fC [protected]\fR"
To be called by the mouse handler to signal that the
mouse is at position \fIpos\fR and the mouse buttons are
in state \fIbstate\fR.
