Well, the documentation says:
"The "current item". In callbacks this is the item the user clicked on.
Otherwise you probably can't make any assumptions about it's value."
So unless you do this in a callback, item() will not return anything useful.
You either need to walk the widget tree and search for someWidget->selected(),
or you set a callback for each entry.
But I am no 2.0 expert... .
