 5# Tix Demostration Program
 6#
 7# This sample program is structured in such a way so that it can be
 8# executed from the Tix demo program "tixwidgets.py": it must have a
 9# procedure called "RunSample". It should also have the "if" statment
10# at the end of this file so that it can be run as a standalone
11# program.

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

63    Hi,
64
65    I have implemented a new image type called "compound". It allows you
66    to glue together a bunch of bitmaps, images and text strings together
67    to form a bigger image. Then you can use this image with widgets that
68    support the -image option. For example, you can display a text string string
69    together with a bitmap, at the same time, inside a TK button widget.
