 955 <h2>wxPython</h2>
 956
 957 <p> wxPython is a <b>GUI toolkit</b> for the <a
 958 href="http://www.python.org/">Python</a> programming language.  It
 959 allows Python programmers to create programs with a robust, highly
 960 functional graphical user interface, simply and easily.  It is
 961 implemented as a Python extension module (native code) that wraps the
 962 popular <a href="http://wxwindows.org/front.htm">wxWindows</a> cross
 963 platform GUI library, which is written in C++.
 964
 965 <p> Like Python and wxWindows, wxPython is <b>Open Source</b> which
 966 means that it is free for anyone to use and the source code is
 967 available for anyone to look at and modify.  Or anyone can contribute
 968 fixes or enhancements to the project.
 969
 970 <p> wxPython is a <b>cross-platform</b> toolkit.  This means that the
 971 same program will run on multiple platforms without modification.
 972 Currently supported platforms are 32-bit Microsoft Windows, most Unix
 973 or unix-like systems, and Macintosh OS X. Since the language is
 974 Python, wxPython programs are <b>simple, easy</b> to write and easy to
 975 understand.
 976
 977 <p> <b>This demo</b> is not only a collection of test cases for
 978 wxPython, but is also designed to help you learn about and how to use
 979 wxPython.  Each sample is listed in the tree control on the left.
 980 When a sample is selected in the tree then a module is loaded and run
 981 (usually in a tab of this notebook,) and the source code of the module
 982 is loaded in another tab for you to browse and learn from.
