QFtp : Connexion to false IP doesn't expirate

Hi,
I'm trying to write a small program using QFtp, and I need to try to connect to several IP and ignore those who hasn't a valid ftp server. But it looks like the signal commandFinished isn't called like it is if you try to connect to an invalid web address. So how can I know that the connexion to the IP is failing and that I should try the next address?
(The FTP example from the documentation report an error when given a false address bug "freeze" when given 1.1.1.1)

I hope my english isn't too bad to be understandable...
Thanks

Process the states returned from QFtp, if you get "Connecting" state for too long, abort the connection and assume host doesn't exist.

I had the same problem. Needed to inform a user that some command (be it connecting or put, get etc.) takes too long. So I created a class that is set on QFtp pointer. I hope it is fine. It takes QFtp isntance pointer, which has to observe and when it's action is started - waits for specified time. If the state doesn't change within that time (suppose this is host looking or connecting) or the data transfer progress doesn't change - it emits timeout signal.
The first timeout (until the first command is executed) is a bit longer here - I assumed this one would take the most of time. Here, have a look at my code. If You see any mistakes, I am opened.
Caution: I didn't inherited from QFtp to have one TimeOutFtp class due to my specific reasons. But of course, this would be the good idea as well.
Hope it helps.

Regards,
Chris.
