3 | # Implements the "TK" standard file selection dialog box. This | |
4 | # dialog box is used on the Unix platforms whenever the tk_strictMotif | |
5 | # flag is not set. | |
6 | # | |
7 | # The "TK" standard file selection dialog box is similar to the | |
8 | # file selection dialog box on Win95(TM). The user can navigate | |
9 | # the directories by clicking on the folder icons or by | |
10 | # selecting the "Directory" option menu. The user can select | |
11 | # files by clicking on the file icons or by entering a filename | |
12 | # in the "Filename:" entry. | |
