 5# Tix Demostration Program
 6#
 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 tixOptionMenu widget -- you can
14# use it for the user to choose from a fixed set of options
15#
