    Default Desktop wallpaper Fade In

    Hi everyone

    I'm pretty much new to the QT world, so I'm trying to learn something by reading codes and stuff. My main problem now is that I need to set a wallpaper, showing it slowly from a black background.
    I googled and tested some methods, but couldn't get it working.
    So I'll just post my little code and ask if someone can explain me a way to make the effect I'm looking for

    Qt Code:
    1. void Desk::set_wall() {
    2. setPixmap(wall_img);
    3. setScaledContents(true);
    4. setGeometry(0, 0, 1280, 1024);
    5. }
    To copy to clipboard, switch view to plain text mode 


    Thanks!

    Actually I removed it and what I posted is the simple code that provides me the wallpaper.
    After trying to get it working with a for and a setAlpha, I gave up and posted here to get some help on the whole thing, because some people draws a rectangle and make it fade out, and I don't know which is the right way to do it.
    I also read on some KDE page online that the setOpacity method its not either a good way.
    So I don't know, I'm stuck on this
