如何创建QML这样的画布，并在该画布上附加XOverlay视频对象？

Java:
final Canvas canvas = new Canvas(); 
canvas.setPreferredSize(new Dimension(200, 200)); 
XOverlay.wrap(video).setWindowID(canvas);

C++
#include <QtGui/QApplication>
#include "qmlapplicationviewer.h"

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

    QmlApplicationViewer viewer;
    viewer.setOrientation(QmlApplicationViewer::ScreenOrientationAuto);
    viewer.setMainQmlFile(QLatin1String("qml/QmlTest1/main.qml"));

    // set the window no border, to do full screen live VIDEO
    viewer.setWindowFlags(
                            Qt::CustomizeWindowHint |
                            Qt::FramelessWindowHint
    );
    viewer.showExpanded();

    return app.exec();
}
