   5 # Tix Demostration Program
   6 #
   7 # This sample program is structured in such a way so that it can be
   8 # executed from the PyTix demo program "tixwidget": 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 using tixwish.
  12
  13 # This file demonstrates how to use multiple columns and multiple styles
  14 # in the tixHList widget
  15 #
  16 # In a tixHList widget, you can have one ore more columns.
