Steve,

Have you tried this.  On my linux (RedHat 8.0) python 2.2.2
I can supply a list of filetypes to the tkFileDialog and when the user
only types a file name (no extension) the selected extension is appended
to the returned filename.  :-




>>> import tkFileDialog
>>> filename = tkFileDialog.asksaveasfilename(filetypes=[("text files",
"*.txt"),
...     ("python source code", "*.py")])

<<< users types aaaa and selected *.txt as file type>>>>


>>> print filename
/usr/python/scripts/aaaa.txt
