http://wiki.qtjambi.info/Converting_java.awt.Image_to_QImage Method on the link above does it the other way around. It converts an Image to a QImage, I'm guessing it shouldn't be too hard to reverse the logic and do it the other way around.

I will however warn you in advance that it isn't exactly fast.. I'll update the page if I find a faster way.
