# 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.
