qml и c ++ с приложением qt quick 2

У меня есть qml GUI моего главного окна. Я только что создал приложение qt quick2, скопировал и вставил графический интерфейс qml моего главного окна в main.qml. Когда я запускаю приложение, оно отображает пустое окно, и мой журнал qml следующий:

    QML debugging is enabled. Only use this in a safe environment.

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

If your example is using QML 2, (such as qmlscene) and the .qml file you 
loaded has 'import QtQuick 1.0' or 'import Qt 4.7', this error will occur. 

To load files with 'import QtQuick 1.0' or 'import Qt 4.7', use the 
QDeclarativeView class in the Qt Quick 1 module.

        anchors.bottom: parent.bottom

    }


}

и автоматически сгенерированный main.cpp:

#include <QtGui/QGuiApplication>
#include "qtquick2applicationviewer.h"

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

    QtQuick2ApplicationViewer viewer;
    viewer.setMainQmlFile(QStringLiteral("qml/convQML/main.qml"));
    viewer.showExpanded();

    return app.exec();
}

Есть идеи, почему это не работает? Я новичок в qml, и я действительно запутался, как это связано с c ++.
