wxPython

wxPython is a GUI toolkit for the Python 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 wxWindows cross platform GUI library, which is written in C++.

Like Python and wxWindows, wxPython is Open Source 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.

wxPython is a cross-platform 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 simple, easy to write and easy to understand.

This demo 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.
