yes jacek,
I had seen QRubberband and have been able to draw the rubber band rectangles directly on image .

But my question is : Initially I want to draw certain rectangles on image( I mean on QLabel) having their coordinates specified in our program code itself. And then I should be able to rubber band it or modify it by mouse .

So editing is next phase, firstly I want to draw rectangles on image via coordinats in program code in an array .
I hope I have been able to make you understand the problem

And Ya ofcourse thanx a lot for help..
