-This is the initial CVS checkin of the Gnome Accessibility Project's Assistive Technology Service Provider Interface.
+README
-At the moment it does not include IDL for all of the SPI, but it does provide a prototype implementation of the core of the out-of-process accessibility service, the 'registry'.
+at-spi version 1.9.0
-Accessible applications will register with this registry service (via OAF) and adaptive/assistive technologies will register with the service as well, to indicate their interest in receiving UI events. ATs can also use the registry's services programmatically to query accessible applications.
+This version of at-spi requires atk 1.17.0 or later.
+This version of at-spi is a MAJOR break from previous versions.
+It has been completely rewritten to use D-Bus rather than
+ORBIT / CORBA for its transport protocol.
-Running the test programs:
-============================
+*** Welcome to the Gnome Accessibility Project! ***
-At the moment the only clients and 'apps' are the test at client and test app in the 'tests' subdirectory.
+If you have not already done so, please visit
-If you have a working ORBit2/OAF installation you can run the tests after adding the registryd directory to OAF's directory list with oaf-sysconf, or by installing Accessibility_Registry.oaf in your 'oafinfo' directory.
+http://developer.gnome.org/projects/gap
-You can then run './at' and './app' from the 'test' directory, to see 'app' register as an application, and 'at' as a listening client. OAF should take care of the job of bootstrapping the registry daemon ('registryd') for you.
+for background information on accessibility, the Gnome
+Accessibility Project, mailing list info, and project status.
-At the moment app and at deregistration are broken, so you are advised to kill the registry daemon if you exit either 'at' or 'app' instances. You may run as many instances of each as you like, concurrently - you may find it useful to do so in separate terminal windows.
+Contents of this package ==================================
+The directories within this package are arranged as follows:
-'at' connects to the registry as an event listener, then queries the service for the number of virtual desktops (currently always 0 or 1), and queries each desktop for the accessible applications it is running. It then prints out the name of each such application (as reported by the application's accessibility interfaces), and then waits to receive events.
+ idl : This directory contains the interface definitions
+ (in Interface Definition Language) for the
+ accessibility support interfaces exposed by
+ the AT central registry, accessible applications,
+ and UI components.
+ This is possibly historic. The idl formed the basis
+ for the XML protocol definitions now located
+ in the directory "xml".
-'app' connects to the registry as an application, then dispatches an event which the registry should relay to all registered listeners. Thus instances of 'app' run after 'at' should cause the 'at' instances to receive events.
+ registryd : This directory contains code specific to the
+ central accessibility registry, and the registry
+ executable is built in this directory.
-
--Bill
+ 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
+ types.
