how to use( include) QObjectPrivate，QUrlnfo？
i want to rewrite QFtp class. so how to use( include) QObjectPrivate，QUrlnfo？
I don't think QUrlnfo exists anymore.
Personally, I'd suggest you just use libcurl as it's the most common network library out there, maybe with a C++ wrapper. If you want you can even build a Qt-style wrapper on top of libcurl to simulate what QFtp did
