   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.
