Can you clarify what you want the above code to do? If you are trying to add an additional Rectangle to the scene described in main.qml, one possible problem is that the Rectangle created is never parented to another item. If you modified the above to something like:

...
QDeclarativeItem *rect = qobject_cast<QDeclarativeItem*>(component.create(context))

view.setSource(QUrl("main.qml"));
rect->setParentItem(view.rootObject())
...

It should be successfully inserted into the scene.
