qtnetwork - Problem in developing FTPClient using Qt -

i trying implement ftpclient in using qt network .

how can handle exceptional cases during downloading network cable unplugged , not internet connection gone etc.. ?

how can ftpclient can come know such event , there such kind of notification available ?

i have tried use signals done(bool) , ommandfinished ( int id, bool error ) m not getting sort of signal.

you seem use qftp, obsolete. should use qnetworkreply (and qnetworkaccessmanager), has finished() , error() signals: qnetworkreply documentation.
