Cannot set FullScreen from QML with QQuickWindow

[ChrisTof]

I have code:

QGuiApplication app(a, nullptr);
QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("../main.qml")));
QQuickWindow *window = qobject_cast<QQuickWindow*>(engine.rootObjects().at(0));
if (!window)
    return 1;
window->show();

return app.exec();

I can set Fullscreen from within C++ by typing:

window->setVisibility(QWindow::FullScreen);

or

window->showFullScreen();

But, I would really like to do this from within main.qml. Typing:

Window{
    visibility: Window.FullScreen
    visibility: "FullScreen"
    ...

does not help. Any ideas?

@ChrisTof said in Cannot set FullScreen from QML with QQuickWindow:

I think you can just use the below code without window->show()

    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

    QQuickWindow *window = qobject_cast<QQuickWindow*>(engine.rootObjects().at(0));
    if (!window)
        return 1;

    return app.exec();

Window {
    visibility: Window.FullScreen

    title: qsTr("Hello World")
    color: 'lightblue'
}
