That's right. The web interface remote uses the same layout as yours.

But my inquiries about this topic were about 30 minutes... perhaps I will continue next month to search a solution.
Or have you already a good idea how to implement something like this?

I presume you are attempting to create the QML object statically? This will prevent the main.qml file from being loaded as the component that contains the error cannot be instantiated. If you create the QML object dynamically like this

Code:

function createObject(sourceFile, parentObject) {
    var component = Qt.createComponent(sourceFile);
    
    if (component.status == Component.Ready) {
        var guiObject = component.createObject(parentObject);
        
        if (guiObject == null) {
            console.log("Error creating object");
        }
        else {
            return guiObject
        }
    }
    else {
        console.log(component.errorString());
    }
}

then you can handle the error. In the above code, if the created component does not have status == Component.Ready, then the error is logged to the console. Otherwise, the created object is returned with parent as specified.
