A note. the samples uses images that are stored in resource file.
not directly off hard disk.

the last sample loads it from file

 QPixmap bkgnd("/home/user/Pictures/background.png"); // from file if windows it would be c:/blabla/x.png
 bkgnd = bkgnd.scaled(this->size(), Qt::IgnoreAspectRatio);
  QPalette palette;
  palette.setBrush(QPalette::Background, bkgnd);
 this->setPalette(palette);

@mrjj yes of course but... i want to escape window rectangle ( with exit etc buttons)

@EpicLoyd
you mean you want to have a window with no frame and buttons ?
you can try
setWindowFlags(Qt::FramelessWindowHint);
in the constructor of the window.

ahh just saw the other post.
look at this

make sure the PNG do have transparent areas.

Super.
So you might need to add a button to close it :)
