# tkfbox.tcl --
#
# Implements the "TK" standard file selection dialog box. This
# dialog box is used on the Unix platforms whenever the tk_strictMotif
# flag is not set.
#
# The "TK" standard file selection dialog box is similar to the
# file selection dialog box on Win95(TM). The user can navigate
# the directories by clicking on the folder icons or by
# selecting the "Directory" option menu. The user can select
# files by clicking on the file icons or by entering a filename
# in the "Filename:" entry.
