Detailed Description

The QWSMouseHandler class is a mouse driver/handler for Qt/Embedded.

The mouse driver/handler handles events from system devices and generates mouse events.

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.

Member Function Documentation

QWSMouseHandler::QWSMouseHandler ()

Constructs a mouse handler. This becomes the primary mouse handler.

Note that once created, mouse handlers are controlled by the system and should not be deleted.

QWSMouseHandler::~QWSMouseHandler () `[virtual]`

Destroys the mouse handler. You should not call this directly.

void QWSMouseHandler::calibrate ( QWSPointerCalibrationData * ) `[virtual]`

This method is reimplemented in the calibrated mouse handler to set calibration information (from, for instance, the QPE calibration screen). This version does nothing.

void QWSMouseHandler::clearCalibration () `[virtual]`

This method is reimplemented in the calibrated mouse handler to clear calibration information. This version does nothing.

void QWSMouseHandler::mouseChanged ( const QPoint & pos, int bstate ) `[protected]`

When a mouse event occurs this function is called with the mouse's position in pos, and the state of its buttons in bstate.
