    How to annotate an image displayed in QGraphicsView?
    I should be able to select a region of interest(an rectange) by mouse and then attonate it.![alt text](dc2ced28-4868-4416-9a1f-3de0d934c89a-image.png image url)
    An example is shown above of how the attonation should be.

      @Girin

      Can you explain what you mean by "attonation"?

      Your image looks like a MRI / MRT-image?!

      Edit:

      Do you mean "annotation"?
      So basically you want to draw a rectangle around your area?!


      If debugging is the process of removing software bugs, then programming must be the process of putting them in.

          @Pl45m4 Sorry!, yes it is annotation.
          I want to select a region in the image, so the i can do some image processing on that particular region.

            Have a look at this thread. The OP there asked for something similar.

            You could solve it with QRubberBand or you paint your own rect / rectItem after clicking and while moving your mouse.
