| 8 | # executed from the Tix demo program "tixwidgets.py": it must have a
|
|---|
| 9 | # procedure called "RunSample". It should also have the "if" statment
|

|

|
|---|
| 14 | # use it for the user to select a directory. For example, an installation
|
|---|
| 15 | # program can use the tixDirTree widget to ask the user to select the
|
|---|
| 16 | # installation directory for an application.
