The Mouse Calibration example demonstrates how to write a simple program using the mechanisms provided by the QWSMouseHandler class to calibrate the mouse handler in Qt for Embedded Linux. Calibration is the process of mapping between physical (i.e. device) coordinates and logical coordinates. QObject Class Reference - PyQt download | SourceForge.net The QObject class is the base class of all Qt objects. QObject is the heart of the Qt Object Model. The central feature in this model is a very powerful mechanism for seamless object communication called signals and slots. You can connect a signal to a slot with connect() and destroy the connection with disconnect().
