# Tix Demostration Program
|
|
#
|
|
# This sample program is structured in such a way so that it can be
|
|
# executed from the Tix demo program "widget": 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 how to use the TixTree widget to display
|
|
# dynamic hierachical data (the files in the Unix file system)
