- # 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.
-
- # A very simple demonstration of the tixGrid widget
