Classes:

- FileDialog
- LoadFileDialog
- SaveFileDialog

This module also presents tk common file dialogues, it provides interfaces
to the native file dialogues available in Tk 4.2 and newer, and the
directory dialogue available in Tk 8.3 and newer.
These interfaces were written by Fredrik Lundh, May 1997.

FileDialoga  Standard file selection dialog -- no checks on selected file.

    Usage:

        d = FileDialog(master)
        fname = d.go(dir_or_file, pattern, default, key)
        if fname is None: ...canceled...
        else: ...open file...

    All arguments to go() are optional.

    The 'key' argument specifies a key in the global dictionary
    'dialogstates', which keeps track of the values for the directory
    and pattern arguments, overriding the values passed in (it does
    not keep track of the default argument!).  If no key is specified,
    the dialog keeps no memory of previous state.  Note that memory is
    kept even when the dialog is canceled.  (All this emulates the
    behavior of the Macintosh file selection dialogs.)
