Detailed Description

The QWSPointerCalibrationData class is a container for mouse calibration data in Qt for Embedded Linux.

Note that this class is only available in Qt for Embedded Linux.

QWSPointerCalibrationData stores device and screen coordinates in the devPoints and screenPoints variables, respectively.

A calibration program should create a QWSPointerCalibrationData object, fill the devPoints and screenPoints variables with its device and screen coordinates, and pass the object to the mouse driver using the QWSMouseHandler::calibrate() function.

See also QWSCalibratedMouseHandler and Mouse Calibration Example.
