# 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 write a new Tix widget class.
#

# ArrowBtn.tcl --
#
#	Arrow Button: a sample Tix widget.
