| # Tix Demostration Program | |
| # | |
| # This sample program is structured in such a way so that it can be | |
| # executed from the Tix demo program "widget": it must have a | |
| # procedure called "RunSample". It should also have the "if" statment | |
| # at the end of this file so that it can be run as a standalone | |
| # program using tixwish. | |
| # This file demonstrates the use of the tixOptionMenu widget -- you can | |
| # use it for the user to choose from a fixed set of options | |
| # | |
