|
|---|
| 8 | # executed from the Tix demo program "tixwidgets.py": it must have a
|
|---|
| 9 | # procedure called "RunSample". It should also have the "if" statment
|
|---|
| 10 | # at the end of this file so that it can be run as a standalone
|
|---|
| 11 | # program.
|

| 12 |
|

| 13 | # This file demonstrates the use of the tixComboBox widget, which is close
|
|---|
| 14 | # to the MS Window Combo Box control.
