Thank you John for your reply.
I have made the modifications and it does print inside the listbox,
however they are all printed on the same line.
My files are named Name.0 Name.1 Name.2 Name.3 etc so I would like
them to be printed sorted on a separate line. When I did a
type(fileNames) it showed me that it was in unicode and printed
character per line, so I tried it this way
listFileNames = str(fileNames).split(' ')
for fileName in listFileNames:
self.lbox.insert(0, fileName)
it works but does not print sorted.
it prints
name.2
name.1
name.0
name.3
Thank you for all your help.
