Thanks once again.
Well, I thought it was emitting signal.
If it isn't emitting signal, then you can create your own copy routine (or class or whatever), that will emit required signal. You might even try to make your own QFile derivative that supports those signals, but that might be too difficult. If I were you I'd write class (based on Q_OBJECT, of course) for copying files, and made it emit signals you need.
