This version of at-spi is a major break from version 1.x.
It has been completely rewritten to use D-Bus rather than
ORBIT / CORBA for its transport protocol.
A page including instructions for testing, project status and
TODO items is kept up to date at:

For bug reports, feature requests, patches or enhancements please use
the AT-SPI project on bugzilla.gnome.org. Use the at-spi2-atk component for
bugs specific to this module.
A git repository with the latest development code is available at:
Code in this repository depends on at-spi2-core resources. The

The project was started with a D-Bus performance review
the results of which are available on the GNOME wiki. Keep in
mind that the D-Bus AT-SPI design documents on this page

Contents of this package
This package includes libatk-bridge, a library that bridges ATK to the new
D-Bus based AT-SPI, as well as a corresponding module for gtk+ 2.x. Gtk+ 3.x
now links against libatk-bridge directly rather than requiring it to be loaded
as a module.
These libraries depend on the at-spi2-core code that contains the daemon for
registering applications, D-Bus helper libraries and the AT-SPI D-Bus specifications.
Building this package
In order to build at-spi2-atk you will need:
- Python 3.5
Additionally, you will need the development files for:
- GTK+ 3.x
To build and install this package, you will typically need to run `meson` to
configure the build process, and Ninja to run the compilation and installation
# Configure the build and initialize the build directory
meson _build .
# Enter the build directory
# Build the project
# Install the project
sudo ninja install
To run the test suite, use `meson test` from the build directory.
The directories within this package are arranged as follows:
Contains a framework for registering objects
with a D-Bus connection and for routing messages to
the implementing object.
Used by the ATK adaptor.
This directory contains code that bridges
the at-spi to the GTK+ toolkit, and which is
loaded at runtime by GTK+-based Gnome applications.
The 'bridge' automatically registers GTK+-2.0
applications with the accessibility registry,
and relays UI events from application to registry.
It is also responsible for servicing requests from
the registry to register handlers for specific event
Contains tests for atspi.
