 958 <h2>wxPython</h2>
 959
 960 <p> wxPython is a <b>GUI toolkit</b> for the <a
 961 href="http://www.python.org/">Python</a> programming language.  It
 962 allows Python programmers to create programs with a robust, highly
 963 functional graphical user interface, simply and easily.  It is
 964 implemented as a Python extension module (native code) that wraps the
 965 popular <a href="http://wxwindows.org/front.htm">wxWindows</a> cross
 966 platform GUI library, which is written in C++.
 967
 968 <p> Like Python and wxWindows, wxPython is <b>Open Source</b> which
 969 means that it is free for anyone to use and the source code is
 970 available for anyone to look at and modify.  Or anyone can contribute
 971 fixes or enhancements to the project.
 972
 973 <p> wxPython is a <b>cross-platform</b> toolkit.  This means that the
 974 same program will run on multiple platforms without modification.
 975 Currently supported platforms are 32-bit Microsoft Windows, most Unix
 976 or unix-like systems, and Macintosh OS X. Since the language is
 977 Python, wxPython programs are <b>simple, easy</b> to write and easy to
 978 understand.
 979
 980 <p> <b>This demo</b> is not only a collection of test cases for
 981 wxPython, but is also designed to help you learn about and how to use
 982 wxPython.  Each sample is listed in the tree control on the left.
 983 When a sample is selected in the tree then a module is loaded and run
 984 (usually in a tab of this notebook,) and the source code of the module
 985 is loaded in another tab for you to browse and learn from.
