Ok thanks a lot

Hi again, relating with my first question, I think that's impossible to paint under a widget without clearing the background in the way that I want. I've tried different ways: setting transparent background, different composition modes, etc. but no success: everytime clears the background. The only solution is to paint again all the image everytime that the rubberband changes its position or size. But as you can see, this is very inefficient specially if the image has a big size. The problem is that the rubberband is painted with some delay since the mouse cursor and it's a bit annoying. I'm thinking in other solutions: does anybody knows a way to paint the image in background mode and in a specified fixed position and size like if it was permanently "painted" on the widget? So it releases of painting everytime the image. I think that a QLabel wouldn't be useful because it wouldn't be able to paint the rubberband under the label...
