| 8 | # executed from the Tix demo program "tixwidgets.py": it must have a
|

| 9 | # procedure called "RunSample". It should also have the "if" statment

| 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.
