| 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. |
