# FIXME List:
|
|
# * Problems with flickering related to ERASE_BACKGROUND
|
|
# and the splitters. Might be a problem with this 2.5 beta...?
|
|
# UPDATE: can't see on 2.5.2 GTK - maybe just a faster machine :)
|
|
# * Demo Code menu?
|
|
# * Annoying switching between tabs and resulting flicker
|
|
# how to replace a page in the notebook without deleting/adding?
|
|
# Where is SetPage!? tried freeze...tried reparent of dummy panel....
|
|
|
|
# TODO List:
|
|
# * UI design more prefessional
|
|
# * save file positions (new field in demoModules) (@ LoadDemoSource)
|
|
# * Update main overview
|
|
|
|
# * Why don't we move _treeList into a separate module

<h2>wxPython</h2>
|
|
|
|
<p> wxPython is a <b>GUI toolkit</b> 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++.
|
|
|
|
<p> Like Python and wxWindows, wxPython is <b>Open Source</b> 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.
|
|
|
|
<p> wxPython is a <b>cross-platform</b> 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 <b>simple, easy</b> to write and easy to
|
|
understand.
|
|
|
|
<p> <b>This demo</b> 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.
