Paint Function over QGaprhicsItem is not called [ Line connecting two box]

  • Hi All,
    I am working over creation of work flow. I have create a two box and connected with a line. All the child items which I have created are QGaphicsItem and I have created QGraphicScene with QGraphicView. Every thing is working fine until I move out of the view. If I move the two box out of the view and bring it back to the view. I am not able to see the line even though I refresh my screen or minimize my application the line is not visible. But it start to visable when I move my scroll bar. Kindly let me know what is the issue and how to fix it.
