ApplicationWindow as root object result in error

[codeman]

Hello friends,

I have expose one c++ classes to qml in a main.cpp file like this:

int main(int argc, char** argv)
{
    QGuiApplication app(argc, argv);
 
 
    qmlRegisterType<MyTestClass>("Test", 1, 0, "Test");
 
 
    QQuickView view;
    view.resize(800, 480);
    view.setResizeMode(QQuickView::SizeRootObjectToView);
    view.setSource(QUrl("qrc:///main.qml"));
    view.show();
    return app.exec();
}

int main(int argc, char** argv)
{
    QGuiApplication app(argc, argv);


    qmlRegisterType<MyTestClass>("Test", 1, 0, "Test");


    QQuickView view;
    view.resize(800, 480);
    view.setResizeMode(QQuickView::SizeRootObjectToView);
    view.setSource(QUrl("qrc:///main.qml"));
    view.show();
    return app.exec();
}

To copy to clipboard, switch view to plain text mode 

But my root object in qml is a ApplicationWindow object. So I get a

QQuickView only supports loading of root objects that derive from QQuickItem.

So when I avoid the main.cpp I have to run the qml file with qmlscene. But I want to have an exe file. How can I use an main.cpp in combinatiion with a ApplicationWindow root object in a qml file?

Yours,
