# 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 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.
|
