  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 "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.
