5 # Tix Demostration Program
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 using tixwish.
13 # This file demonstrates the use of the tixDirTree widget -- you can
14 # use it for the user to select a directory. For example, an installation
15 # program can use the tixDirTree widget to ask the user to select the
16 # installation directory for an application.
