Qt6 QScreen setOrientationUpdateMask()

[Kuzma30]

I use b2qt distro.
My app is QML based. I need rotate context of the screen by 90degree. I have not accelerometer in my system and screen must be rotated all time.
After googling I found such example code

    QScreen* screen = QGuiApplication::primaryScreen();
    if(screen){
          screen->setOrientationUpdateMask(Qt::PortraitOrientation);
    }

but it not compile on QT6.
What is a proper way to hardcode screen orientation for QT6 app?

After some research I do
Window {
id: root
contentOrientation: Qt.InvertedLandscapeOrientation
visible: true

Rectangle{
    id: root_w
    width: 1920
    height: 1200
    transform: Rotation {
        angle: 270
        origin.x: root.height / 2
        origin.y: root.height / 2
    } 

// code here
}
