# 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 compound image to add
# colors in Notebook tabs.
#

    # Create the notebook widget and set its backpagecolor to gray.
    # Note that the -backpagecolor option belongs to the "nbframe"
    # subwidget.

    #

    #
    # Notice that the -window option must be set to the nbframe
    # subwidget of the notebook because the image will be displayed
    # in that widget.
