# Tix Demostration Program
#
# This sample program is structured in such a way so that it can be
# executed from the Tix demo program "tixwidgets.py": 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.

# This file demonstrates the use of the tixPanedWindow widget. This program
# is a dummy news reader: the user can adjust the sizes of the list
# of artical names and the size of the text widget that shows the body
# of the article.

    Hi,

    I have implemented a new image type called "compound". It allows you
    to glue together a bunch of bitmaps, images and text strings together
    to form a bigger image. Then you can use this image with widgets that
    support the -image option. For example, you can display a text string string
    together with a bitmap, at the same time, inside a TK button widget.
