|

|
7 # This sample program is structured in such a way so that it can be |
|
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. |
