SOCKSv4 and QT 4.6.x

[memus]

Hi there,
I need to find out how to check is host support SOCKSv4/SOCKSv5 proxy connections.
For SOCKSv5 i can do that:

proxy.setType(QNetworkProxy::Socks5Proxy);

proxy.setType(QNetworkProxy::Socks5Proxy);

To copy to clipboard, switch view to plain text mode 

but how about SOCKSv4?

any ideas?

Thanks for reply.
