    The frame is painted before the pixmap so you have no other chance then doing the painting by yourself.

      How exactly would I do that?
      I can probably figure out most of it, I just need a starting point.

        Hi,

        Create a subclass of QLabel and overload the paintEvent method. There you call the base class implementation and after that, do your custom drawing on top of your image.

          That's what I figure, but can I use that class in qt designer after?
          Also I don't want to draw on top of the image, I want to draw the image with a bevel effect.

            Since you do the drawing on your own then you can draw whatever you want.

              Try to add padding to see if it helps.
              padding is added between border and contents.

                @JoeCFD that just makes it ugly, the image becomes smaller, won't work in my case.

                  @Christian-Ehrlicher Do I have access to the standard label paint event, to look at as an example? As well as qframe's probably.

                    Hm, no, it doesn't seem like I can just reimplement the paint event here... :/

                      Can you use a combination of drawImage and clipPath in a custom PaintEvent to achieve what you want?

                        Sure, but I can't just call super().whatever to draw the rest because that the draws the image itself as well..
