# 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 tixDirSelectDialog widget:
# it allows the user to select a directory.
#
proc RunSample {w} {

    # Create an entry for the user to input a directory. If he can't
    # bother to type in the name, he can press the "Browse ..." button
    # and call up the diretcory dialog
    #
