There is a FileSelectDialog in Tix that has a dircmd option according to the Tix documentation.
There is also allegedly a 'hidden' check-box subwidget that controls whether hidden files are shown. Again I couldn't find how to access this.
This combo looks like the best solution if I can find how to make it work. Its the logical solution and I'm astounded that none of the common GUIs seem to offer it. (Although I've been building GUIS for over 20 years and never needed it until now! So maybe not so surprising). I'm hoping to buy out some time over the next couple of days to seriously explore the Tix dialogs.
there only minimal pattern support matching, but there is no way to subclass the thing and feed it your own list of file and directory
This is true and it is because Tkinter has used the underlying GUI toolkit rather than building open/save from scratch. (Native Tk
offers no standard dialogs for file operations!) However there is another option in the shape of the Dialog module which is designed to allow you to easily build a custom dialog of your own design. This could be done using the Tix tree view widget for example and you could then build in a file filter operation. (A search may even reveal that somebody has done this already... I think that's what the Tk code Laura posted was doing))
I can only assume that windows users don't get this problem.
Its got nothing to do with the OS, the same limitations apply in all cases. They have taken the minimum subset of options when they built the common dialogs. But the standard Windows dialog doesn't offer exclusion options either, so even if they had offered platform specific hooks, it would not have helped on Windows. wxPython does the same, so has the same limitations.
Do any of the other graphical packages avoid this problem?
The GTk dialogs on my Linux box have slightly more sophisticated options so I'd guess that PyGTK at least will offer more in the API (But even they don't appear to have filter out capability). PyQt/SIDE probably offers more too but I don't know very much about Qt. One possibility on Windows is that the list of folders shown is con trolled by the users registry settings in the file explorer. You can choose to hide "system files" in the Explorer view and that sets a registry flag. I haven't checked but its possible that the Windows open/save dialogs respect that setting.
