Error: Unqualified access [unqualified]

[DeSGuN]

Can anyone tell me what the problem is? Python methods he sees, tried to paste mainwindows.backend

// main.qml
ApplicationWindow {
    id: mainwindows
    visible: true
    flags: Qt.FramelessWindowHint
    width: Screen.width
    height: Screen.height
    title: "HelloApp"
    
    property var conts: backend // there is a problem here Unqualified access [unqualified]

# python
if __name__ == "__main__":
    app = QApplication(sys.argv)
    engine = QQmlApplicationEngine()
    
    controller  = MainWindow()
    engine.rootContext().setContextProperty("backend", controller)
    print("Controller registered:", bool(controller)) 
    engine.load("main.qml")
    sys.exit(app.exec())

Hi,

Shouldn't that be const ? You wrote conts.

Using setContextProperty is not recommended anymore. Use a QML singleton or setInitialProperties on the engine.

@SGaist I didn't quite understand in python there are several methods example: backend.data() then the backend gives an error Unqualified access [unqualified]

@GrecKo Thank you, I set setInitialProperties and the errors disappeared
