Recalibrate

[ken536]

In my current project I wan't to make it possible to recalibrate my touchscreen. I'm using tslib and to recalibrate I just need to delete the calibration file and reboot.

But how to do that, I can't make a button to delete, cause it is the touchscreen itself.
I want to press the touchscreen while booting linux/qt and when qt find it is pressed, it has to wait for x seconds and then check again. If still pressed: delete calibration file.

I tried this
@
QApplication a(argc, argv);

if (a.mouseButtons() & Qt::LeftButton)
{
    sleep(5);
    if (a.mouseButtons() & Qt::LeftButton)
    {
        qDebug() << "reset";
    }
}

@

But this doesn't work.. (it doesn't show "reset")

It seems that mouseButtons aren't updated?

Should a touch on the touchscreen be seen as a Qt::LeftButton on the mouseButtons flag? How can I fake a mouseevent so this flags update?
