QFtp hidden files/folder's list

Dear all,

I am using QFtp class for getting directory list from the FTP Server.

The QFtp's list () function doesn't gives hidden files/folders.

I need a list with hidden files.

So I am using rawCommand () method for getting dir LIST.
--> rawCommand ( "PASV" ) -----reply-------> 227 entering into passive mode ( ......)
after calculating port value, I think I need to open a data connection for receiving folder list.
can anyone help me with some code for opening data connection ?

-->rawCommand ( "LIST -a" ) ----- no reply for this.

Regards
jay.
