Python

- - Python is an interpreted, interactive, object-oriented programming - language often compared to Tcl, Perl, Scheme, or Java. - -

Python combines remarkable power with very clear syntax. It has - modules, classes, exceptions, very high level dynamic data types, and - dynamic typing. There are interfaces to many system calls and - libraries, and new built-in modules are easily written in C or - C++. Python is also usable as an extension language for applications - that need a programmable interface.

wxWindows

- - wxWindows is a free C++ framework designed to make cross-platform - programming child's play. Well, almost. wxWindows 2 supports Windows - 3.1/95/98/NT, Unix with GTK/Motif/Lesstif, with a Mac version - underway. Other ports are under consideration.

- - wxWindows is a set of libraries that allows C++ applications to - compile and run on several different types of computers, with minimal - source code changes. There is one library per supported GUI (such as - Motif, or Windows). As well as providing a common API (Application - Programming Interface) for GUI functionality, it provides - functionality for accessing some commonly-used operating system - facilities, such as copying or deleting files. wxWindows is a - 'framework' in the sense that it provides a lot of built-in - functionality, which the application can use or replace as required, - thus saving a great deal of coding effort. Basic data structures such - as strings, linked lists and hash tables are also supported. - -

-

wxPython

- - wxPython is a Python extension module that encapsulates the wxWindows - GUI classes. Currently it is only available for the Win32 and GTK - ports of wxWindows, but as soon as the other ports are brought up to - the same level as Win32 and GTK, it should be fairly trivial to - enable wxPython to be used with the new GUI. - -

- - The wxPython extension module attempts to mirror the class heiarchy - of wxWindows as closely as possible. This means that there is a - wxFrame class in wxPython that looks, smells, tastes and acts almost - the same as the wxFrame class in the C++ version. Unfortunately, - because of differences in the languages, wxPython doesn't match - wxWindows exactly, but the differences should be easy to absorb - because they are natural to Python. For example, some methods that - return multiple values via argument pointers in C++ will return a - tuple of values in Python. - -

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++. - There is still much to be done for wxPython, many classes still need - to be mirrored. Also, wxWindows is still somewhat of a moving target - so it is a bit of an effort just keeping wxPython up to date. On the - other hand, there are enough of the core classes completed that - useful applications can be written. +

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. - wxPython is close enough to the C++ version that the majority of - the wxPython documentation is actually just notes attached to the C++ - documents that describe the places where wxPython is different. There - is also a series of sample programs included, and a series of - documentation pages that assist the programmer in getting started - with wxPython. +

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. - """ +""" #---------------------------------------------------------------------------- #---------------------------------------------------------------------------- if __name__ == '__main__': + __name__ = 'Main' main() #----------------------------------------------------------------------------
