if you only need to hide hidden files, please see my other post. If you
need a more versatile file dialog widget, you might want to consider
wrapping an existing tcl widget for tkinter, this is usually rather easy
once you understand how it is done (all you need is mostly the man page
and a little time) and might save you a lot of headaches.
One example that might be interisting is here:

You might also want to try the Tix.ExFileSelectDialog, it is rather
dated, but actually has a switch to toggle hidden files on/off and
wildcard filtering capabilities. Unfortunately here with debian jessie I
can only test it with Tcl, with python for some reason I get a
segfault :-(

Best regards

Michael

I realize that command does have its fascination, even under
circumstances such as these, but I neither enjoy the idea of command
nor am I frightened of it.  It simply exists, and I will do whatever
logically needs to be done.
