Tutorial: Mouse Pointer Calibration

Calibration

Qt Extended contains built-in support for calibration but it is disabled by default on almost all platforms. To enable calibration support:

1. Use a touch screen pointer driver that supports calibration, such as the TPanel driver.

   This configuration will add the Recalibrate application to the devices settings list.

   A working /etc/pointercal must be shipped with any touchscreen device, as calibrate no longer runs at first use.

2. To support a calibrated touch screen, PrimaryInput=Touchscreen must included in the [Device] group of the defaultbuttons.conf see Device Profiles

To manually start the calibration on a Qt Extended device, run:

    qcop service send Launcher "execute(QString)" "calibrate"
