   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 using tixwish.
  12
  13 # This file demonstrates the use of the tixScrolledHList widget.
