 944 <h2>wxPython</h2>
 945
 946 <p> wxPython is a <b>GUI toolkit</b> for the <a
 947 href="http://www.python.org/">Python</a> programming language.  It
 948 allows Python programmers to create programs with a robust, highly
 949 functional graphical user interface, simply and easily.  It is
 950 implemented as a Python extension module (native code) that wraps the
 951 popular <a href="http://wxwindows.org/front.htm">wxWindows</a> cross
 952 platform GUI library, which is written in C++.
 953
 954 <p> Like Python and wxWindows, wxPython is <b>Open Source</b> which
 955 means that it is free for anyone to use and the source code is
 956 available for anyone to look at and modify.  Or anyone can contribute
 957 fixes or enhancements to the project.
 958
 959 <p> wxPython is a <b>cross-platform</b> toolkit.  This means that the
 960 same program will run on multiple platforms without modification.
 961 Currently supported platforms are 32-bit Microsoft Windows, most Unix
 962 or unix-like systems, and Macintosh OS X. Since the language is
 963 Python, wxPython programs are <b>simple, easy</b> to write and easy to
 964 understand.
 965
 966 <p> <b>This demo</b> is not only a collection of test cases for
 967 wxPython, but is also designed to help you learn about and how to use
 968 wxPython.  Each sample is listed in the tree control on the left.
 969 When a sample is selected in the tree then a module is loaded and run
 970 (usually in a tab of this notebook,) and the source code of the module
 971 is loaded in another tab for you to browse and learn from.
