Hi,
Your message is a bit confusing: do you want to _get_ the color of the pixel (as in the body of your message), or do you want to _set_ that color?
What have you tried before? What did not work as you expected?

Not that I'd done this but you
might try these:
QPixmap::grabWidget()
QPixmap::toImage()
QImage::pixel()
