# 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 inside NoteBook

# widgets. This file is basically a cross-over of NoteBook.tcl and CmpImg.tcl

#

    # Note that the -backpagecolor option belongs to the "nbframe"

    # subwidget.
