     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.py": 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 tixBalloon widget, which provides

    14 # a interesting way to give help tips about elements in your user interface.

    15 # Your can display the help message in a "balloon" and a status bar widget.
