Все это будет в svn trunk и не факт что появится в ветке 2.8. Так что “кто куды, а мы к зайцам” (с), пойду качать svn trunk. Там кстати еще много чего полезного появилось. Если вы пользуетесь стабильной версией 2.8, рекомендую хотя бы попробовать trunk.

Еще вскользь упомянули, что потихоньку развивается wxSymbian и wxQNX. Порт для Symbian мне кажется очень перспективным, да.

What is AxTk?

AxTk (pronounced Ay Ex Tee Kay) is an open source, C++ add-on for wxWidgets that helps developers create highly accessible, talking applications for users with impaired vision. It may also be useful for other impairments that benefit from a simplified user interface.

AxTk features a new menu-based system that is easy to learn and use, in addition to providing adaptation for some existing GUI controls and dialogs. The developer can choose whether to use the menu system, or to adapt an existing application UI, or use a combination of methods.

AxTk is cross-platform (tested so far on Windows XP, Linux and Mac OS X 10.5), and includes text-to-speech classes with the ability to drive SAPI 5, Apple Speech Synthesis Manager, eSpeak, and Cepstral. Other speech engines can be driven by writing additional handlers.

Note that AxTk is a work in progress and the API is subject to change.

What else is AxTk?

There is an additional, higher-level layer for building applications that help the user maintain ‘resource libraries’ for all kinds of files and services. The motivation is to provided simplified access to many resources and activities that are currently spread amongst many applications and web sites. By making this part of AxTk, we increase the chances of providing a really useful, accessible application platform that can be customised in interesting ways for individuals or government sectors. However, this is currently a less well-developed aspect of AxTk and one which you can ignore fo now. The resource demo shows playing of audio albums and reading Epub books (having converted the XHTML content to plain text first).

What about Braille output?

Although nothing is specifically coded yet for Braille devices, they could be supported relatively easily by adding handlers to the wxTextToSpeech system, to output to the device instead of a speech engine.

Why not just use a screen reader?

Screen readers don’t have an in-depth knowledge of the application; in theory, an AxTk application can make use of knowledge of its own structure to make speech more helpful and less verbose. Also, an application’s custom controls are not accessible to screen readers. In additon, AxTk provides an alternative, menu-based user interface that is not so prone to the problems of accessing conventional layouts via a screen reader. Finally, an AxTk application provides support for application-wide colour and text size changes that are harder to achieve in an ad-hoc way.

Is this anything to do with MSAA (Microsoft Active Accessibility)?

No; a different approach is used. Although wxWidgets has some basic MSAA support, other ports have no similar support and it may be hard to create a comprehensive cross-platform solution to accessibility based on OS-level accessibility support. It would still leave applications and users at the mercy of particular screen readers and it would not solve other problems that AxTk sets out to solve: visual adaptation, fine control over speech (such as content voicing), customisable shortcut support, and more.

Having said that, work on integrating MSAA equivalents for other platforms would be very welcome, either as part of AxTk or built into wxWidgets.

How hard is it to use?

Apart from some housekeeping that you can pinch from the sample, the amount of extra code can be small if you’re just adapting existing UIs. For example, to make a dialog self-voicing and responsive to visual appearance changes (assuming the dialog’s controls are in the set of controls currently handled by AxTk):

#include "ax/ax_ui_adaptation.h"
...
class MyDialog: public wxDialog
{
    ...
    AxSelfVoicing m_adapter;
};

MyDialog::MyDialog(...)
{
    ...
    m_adapter.Adapt(this);
}

If you have controls that are not currently handled by AxTk, you can write adapter classes and also handler classes that detect the appropriate controls and create their adapters.

Using the new menu system is also pretty straightforward as you can see from the sample (mainframe.cpp). There are some new concepts such as AxActivator, which handles menu item activation, but there’s plenty in common with conventional wxWidgets programming.

Where and how do I get it?

AxTk is hosted at Google Code and is available via SVN or as a source tarball or zip file.

http://code.google.com/p/axtk/

The discussion group is axtk-dev_at_googlegroups.com.

The documentation is available here:

http://www.anthemion.co.uk/axtk/html/index.html

Are there demos?

Yes; you can download axsample binaries for Windows, Linux and Mac from:

http://www.anthemion.co.uk/axtk/

You can ignore axresourcesample unless you’re interested in the higher-level resource library layer mentioned previously.

Can I contribute?

Please do! See docs/todo.txt for some of the things left to do. You’ll probably find things to do yourself. You can supply patches in the AxTk’s Issue Tracker, or you can ask to be added to the list of project members in order to make changes in SVN.

What’s the build system?

None to speak of. This would make a good contribution. Currently you can use DialogBlocks to generate projects and makefiles for the two samples, which simply include all the AxTk code.

What is the license?

The license is the New BSD License, which is very brief, easy to understand, and industry-friendly. Please see license.txt in the source tarball for details.

I hope you find AxTk useful – or at least, fun to play with.

• Potentially incompatible change: wxExecute() arguments are now quoted if they contain spaces and existing quotes are escaped with a backslash. However, to preserve compatibility, the argument is unchanged if it is already quoted. Notice that this behaviour will change in wxWidgets 3.0 where all arguments will be quoted, please update your code now if you are affected and use only wxWidgets 2.8.9 or later.

This is the first stable release of the wxJSON library. The major version had changed because I introduced some compatibility breaks with the old 0.x versions as well as some new features.

The wxJSON library is now complete and this release should be considered a final beta release.
JSON data format is very stable. It is accredited to be stable forever or, at least, until programming language’s variables are based on numbers, strings, booleans, structures and arrays.

No other feature should have to be added to the library and I think that, after a few months used for discovering and fixing bugs, I will release the stable version 1.0

This will be the good occasion to, eventually, break the compatibility with the old versions 0.x by changing memberfunction’s names and/or parameters.
If you have any comment, suggestion or hint, feel free to write to me or post an answer to this topic.

Разработчики wxWidgets потратили несколько месяцев на создание скриптов для автоматического преобразования документации, и уже достигли той точки, где скрипты уже не могут помочь. В Документация wxWidgets довольно обширна и файлы с документацией в новом формате требуют ручной обработки чтобы исключить ошибки, которые могли появиться в процессе автоматического преобразования.

Итак, мы нуждаемся в вашей помощи для завершения этого процесса в разумные сроки. Все подробности можно найти здесь.

Если вы заинтересованы, но вам надо информация о том, как все настроить, или если у вас есть какие-либо сомнения или вопросы, не стесняйтесь задать их здесь.

Это хорошая возможность:

• Познакомиться с wxWidgets ближе
• Улучшить те части документации, которые вам не очень нравились
• Помочь сделать wxWidgets еще более конкурентоспособным инструментом разработки

This release adds support for Unicode.
