    Hi!

    I have a qlabel, and I make a qpicture with the qpainter and setting this picture to qlabel, is working fine.
    I would like to modify the picture, I would like to save the actual, because there are several versions, but I do not know how.

    Thanks in advance.

            Ok, I solve the problem, change the QPicture to QPixmap, and it is copyable with the copy() method :)

            Thanks
