Hi all,

I'm not sure how to retrieve the list of RosterItems from a RosterManager. If 
my user just connected, I can call fill() to get the server's roster in my 
local roster, that's fine.
But then, I only have RosterItem * getRosterItem  ( const JID & jid ) to get 
one RosterItem.
If I assume first connection, I'm not supposed to know the different JIDs for 
which my roster has a RosterItem. So how can I get this list ? For example, 
to populate the contacts view ? 
Is there an iterator of some kind I can use to crawl the RosterItems list ?

Thanks a lot,

Alban
