Subject: [Accessibility] D-Bus-based accessibility API

Hi!

For those who are not subscribed to the Gnome accessibility list 

or heard otherwise:

Trolltech have released the promised D-Bus-based accessibility 

API. They have made it available at: 

http://labs.trolltech.com/page/Projects/Accessibility/QDBusBridge

They also wrote a poke tool:

http://labs.trolltech.com/page/Projects/Accessibility/IAPoke

Last but not least, they have a ported Dasher to use the API:

http://labs.trolltech.com/page/Projects/Accessibility/QDasher

(They say that they plan to contribute their work back to the 

official Dasher repository once things it has matured a bit.)

The API is close to both IAccessible2 and AT-SPI.

If I understnad the approach that Trolltech has taken correctly, 

then they have:

a) implemented everything that is in IAccessible2 (including the

   improvements that are missing in AT-SPI)

b) implemented everything from AT-SPI that has been left out of

   IAccessible2 because it is available in MSAA

c) _not_ implemented parts of AT-SPI that are unused by the 

   existing assistive technologies and that have therefore also 

   been left out in IAccessible2

Hi Rich!

In the meantime I had a look at Trolltech's D-Bus sources
and have started to 
compare them with the IAccessible2 and AT-SPI APIs.

My first impression is that there is a very large common set
of APIs that is 
shared by all three, some APIs that are individual to only
one of the three, 
and some APIs that are missing on one of the three.

If this is true, then I am concerned myself, but it is more
likely that I did 
not fully and correctly understand the IAccessible2
approach.

I am waiting for Trolltech to answer my questions before I
publish the 
comparision.

Olaf
