Hi,
  I am writing an interface using Qt 4.5 . I have to draw editable
rectangles on top of loaded image  . I used Qpixmap to load the image in the
paintEvent function of the class inheriting QLabel .
But , the problem is that the tool is very slow now as it paints the image
every time rectangle is edited .
Is there a better way to do this ?
Please  reply asap . . .

Thanks
