TreeWidget and ftputil question

[Croteam]

Hello,

I trying to make a ftp software,and I have one question about it. After
user connect to his ftp account,
command e.g.  ftp._dir('') must insert folder and files (from that ftp
host) in Listbox widget and that files in listbox must look like (look
example) :

C:\Python24\Lib\site-packages\idlelib\ObjectBrowser.py
How to I create that??
If anybody have any idea please tell me I will really appreciate that
Thanks!!!
