# 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
#
