[Qt-qml] dynamically updatable model in QML ListView

[vineeth]

I could get this working using :
declView->rootContext()->setContextProperty(...)
to update the model variable used in QML ListBiew, but I think this involves
unnecessary computation.
A more optimal way will be to get a reference to the model of the ListView
and call append on it.
There is a example of this in :
C:\QtSDK\Examples\4.7\declarative\modelviews\listview\dynamiclist\qml\ and I
need to do the same using C++ backend.
Thanks all for the kind reply.
