---|
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 | # selectinf 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. |
