| # Tix Demostration Program |
| # |
| # This sample program is structured in such a way so that it can be |
| # executed from the Tix demo program "tixwidget": 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 how to use multiple columns and multiple styles |
| # in the tixHList widget |
| # |
| # In a tixHList widget, you can have one ore more columns. |
