# 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.
