   6 # This sample program is structured in such a way so that it can be
   7 # executed from the Tix demo program "widget": it must have a
   8 # procedure called "RunSample". It should also have the "if" statment
   9 # at the end of this file so that it can be run as a standalone
  10 # program using tixwish.

  12 # This file demonstrates the use of the tixPopupMenu widget.
