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