[Qt-qml] How to assign an object id?

[Brandon Sun]

Quoted from Qt Doc<http://doc.trolltech.com/4.7-snapshot/qdeclarativedynamicobjects.html>

Also, note that while dynamically created objects may be used the same as
> other objects, they do not have an id in QML.


Although I also think there're requirements that we need manipulate
dynamically created objects by ID, but unfortunately, there's only this
simple sentence in the doc to explain the ID issue.

Maybe nokia guys could tell more on this.

Thanks,
Brandon
