# tk common file dialogues
|
|
#
|
|
# this module 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.
|
|
#
|
|
# 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
|
|
#
|
|
# options for the directory chooser:
|
|
#
|
|
# - initialdir, parent, title: see above
|
|
#
|
|
# - mustexist: if true, user must pick an existing directory
