Show qml elements on top of custom qglwidget viewport

[ecripes]

I create an instance of a class derived from QGLWidget, and set this instance as the viewport on a QDeclarativeView:
@int main(int argc, char *argv[])
{
QApplication app(argc, argv);

QDeclarativeView view;
MyGLWidget glwidget; // QWidget
view.setViewport(&glwidget);
view.setSource(QUrl::fromLocalFile("main.qml"));
view.show();
return app.exec();

}
@
OpenGL code is correctly displayed inside the qml view, but the problem is that any qml elements (like Rectangle) will appear beneath the viewport. I have found very little info in docs about qdeclarativeview::setViewport, except that it comes from QAbstractScrollArea. I am looking for a way to have the viewport widget always appear beneath any QML elements.

Have you found a solution for this problem?

I was trying the same thing, with the same result.
