    Yes, just like the tooltip says.

    Please, next time ask such questions in more appropriate place, like Feedback section.

    Heh, you can use OpenGL to resize image for free (in your case just change the viewport). Or you can use render_to_texture (Framebuffer Object), or you can read directly the pixels with glReadPixels.

    Anyway, if you use renderPixmap, make sure that OpenGL initialization code (like setting perspective matrices, display lists) are in InitializeGL().
