Re: [orca-list] Orca and D-Bus

[Willie Walker <William Walker Sun COM>]

Jason pretty much has it right. :-)

To expand upon this, however, I'll often refer to this as the "Bonobo  
Deprecation" task for GNOME. As outlined in the following WIKI page,  
this task covers AT-SPI, Magnification, and Speech:

http://live.gnome.org/Accessibility/BonoboDeprecation

Magnification and Speech will require work in Orca since the Orca code  
talks directly to some CORBA API's.  For speech, the proposed path is  
deprecating gnome-speech in favor of the current support for  
SpeechDispatcher.  For magnification, we're working on a D-Bus API for  
magnification. The goal is that gnome-mag will be ported to this API  
and the emerging magnification support being done for GNOME Shell will  
also expose this API. Orca will then talk to this new magnification API  
for D-Bus.  For AT-SPI, we expect the new work to be a drop in  
replacement for pyatspi.
