Input Device resetting



  • Currently, I use the touch panel as an input device and start the application on Qt / Embedded.

    Since the target device tends to be affected by noise and the touch panel may become ineffective, the current situation is to create a touch panel kernel object (ts.ko), reset and reload it. Furthermore, restarting the running application is done.

    Here, how do I reset / reload ts.ko and then reconnect the input device by processing on the application without restarting the application?

    A little examination reveals that Qt's input device is defined in QWS_MOUSE_PROTO, and if you used QWSServer :: resumeMouse (), suspendMouse () it was possible to disable → reactivate it, so use it I tried but it was useless.
    I also tried closeMouse () and openMouse () of the QWSServer class, but it did not work.

    Hi and welcome to devnet,

    Are you connecting directly to your touch screen device or are you using /dev/input/mice which should return all mouses in a system. Thus it might be an alternative when you reload your touchscreen module.

Looks like your connection to Qt Forum was lost, please wait while we try to reconnect.
