# Tix Demostration Program

#

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

# executed from the Tix demo program "tixwidgets.py": 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.

# This file demonstrates the use of the tixOptionMenu widget -- you can

# use it for the user to choose from a fixed set of options

#
