     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 #
