      I'd like to capture my application screen each time something changes, and then pass it to image processing.
      When i do it on PaintEvent by QWidget::render to QPixmap, i get a run-time warnings about widget recursive repaint.
      Is there another way to do this without causing repaint ?

      Thanks.
