    Description

      This code used to create a label, fill it with a QImage as its pixmap. The resulting pixmap filled the area displayed on screen. Now the pixmap is super-large, and I can only see a fraction of it:

      QLabel *label=new QLabel();
      label->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);
      label->setScaledContents(true);
      label->setPixmap(QPixmap::fromImage(QImage(":/Images/3DVideoSplashScreen.jpg")));
      label->setFrameStyle(QFrame::Box);
      this->layout()->addWidget(label);
