# Tix Demonstration 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 using tixwish.
# This file demonstrates the use of the tixDirList widget -- you can
# use it for the user to select a directory. For example, an installation
# program can use the tixDirList widget to ask the user to select the
# installation directory for an application.
