QT_QPA_EVDEV_*_PARAMETERS documentation



  • Hello

    Where can I find documentation (googling and searching this site did not help) on format of
    QT_QPA_EVDEV_KEYBOARD_PARAMETERS, QT_QPA_EVDEV_MOUSE_PARAMETERS and QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS environment variables?

    Do I understand right that specifying QT_QPA_EVDEV_MOUSE_PARAMETERS is the same as passing "-plugin evdevmouse:$QT_QPA_EVDEV_MOUSE_PARAMETERS" ? Command line argument syntax is not known to me either.

    My real problem is that I specified " -plugin evdevmouse:/dev/input/event1" and that make my app see touchscreen but coordinate system is ruined, swiping across whole screen moves pointer by a few pixels. So I probably want to specify some scaling, but not sure.
