    Hello friends and QT experts.

    I was just implement a QGraphicsItem Moving, resizing application.
    I have touchscreen display and it is working well and good in windows platform.
    I can easily move or resize QGraphicsItem Over the QGraphicsView.
    but in raspberry pi i can not move or rezie the QGraphicsItem in My TouchScreen Display.

    but with the mouse control i can move or resize the my QGraphicsItem.
    I want to move or resize the my QGraphicsItem over the QGraphicsView in my Raspberry PI Device TouchScreen.

    please Drop your suggestion or any solution.

    Thanks.

      You should identify the precise Qt call/event/signal/whatever which works with mouse but not with touchscreen. Then maybe you have something to Google for to see what the RPi issue might be.
