<h2>wxPython</h2>

<p> wxPython is a <b>GUI toolkit</b> for the <a
href="http://www.python.org/">Python</a> programming language.  It
allows Python programmers to create programs with a robust, highly
functional graphical user interface, simply and easily.  It is
implemented as a Python extension module (native code) that wraps the
popular <a href="http://wxwindows.org/front.htm">wxWindows</a> cross
platform GUI library, which is written in C++.

<p> Like Python and wxWindows, wxPython is <b>Open Source</b> which
means that it is free for anyone to use and the source code is
available for anyone to look at and modify.  Or anyone can contribute
fixes or enhancements to the project.

<p> wxPython is a <b>cross-platform</b> toolkit.  This means that the
same program will run on multiple platforms without modification.
Currently supported platforms are 32-bit Microsoft Windows, most Unix
or unix-like systems, and Macintosh OS X. Since the language is
Python, wxPython programs are <b>simple, easy</b> to write and easy to
understand.

<p> <b>This demo</b> is not only a collection of test cases for
wxPython, but is also designed to help you learn about and how to use
wxPython.  Each sample is listed in the tree control on the left.
When a sample is selected in the tree then a module is loaded and run
(usually in a tab of this notebook,) and the source code of the module
is loaded in another tab for you to browse and learn from.
