   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": 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
