      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 #
