- # tk common file dialogues
- #
- # this module provides interfaces to the native file dialogues
- # available in Tk 4.2 and newer.
- #
- # written by Fredrik Lundh, May 1997.
- #
-
- #
- # options (all have default values):
- #
- # - defaultextension: added to filename if not explicitly given
- #
- # - filetypes: sequence of (label, pattern) tuples. the same pattern
- # may occur with several patterns. use "*" as pattern to indicate
- # all files.
- #
- # - initialdir: initial directory. preserved by dialog instance.
- #
- # - initialfile: initial file (ignored by the open dialog). preserved
- # by dialog instance.
- #
- # - parent: which window to place the dialog on top of
- #
- # - title: dialog title
