详细描述

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

注意，此类只可用于 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 () 函数。
