Hi,

I use this piece of code to find the root QQuickItem (part of my test
suite):

    engine.load(url);

    QObject *rootObject = engine.rootObjects().first();


    QQuickWindow *window = qobject_cast<QQuickWindow*>(rootObject);

    if (window) {

        setTestableRootObject(window->children().first());

    } else {

        setTestableRootObject(rootObject);

    }
