# Tix Demostration Program

#

# This sample program is structured in such a way so that it can be

# executed from the Tix demo program "tixwidgets.py": it must have a

# procedure called "RunSample". It should also have the "if" statment

# at the end of this file so that it can be run as a standalone

# program.

# This file demonstrates the use of the tixBalloon widget, which provides

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

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