    Hi,

    Another query regarding paintevent() only,
    Inspite of having update() or repaint(), paintevent() , is not getting called.

    Ant specific reason.?.

    Thanks,

      Probably wrong signature... did you try using overload?

        We are trying to stream live video in our application.
        We draw image on the QWidget's paint event, to trigger this we call repaint()/update() whenever a new image is available.
        This works perfectly fine for smaller widgets.

        It is not working for larger widgets.

        Note: Size of Image received in accordance with QWidget Size.
