Re: [orca-list] Orca and QT4 applications

[Willie Walker <William Walker Sun COM>]

Hi All:

Work is underway to migrate AT-SPI from CORBA to D-Bus: see 
http://live.gnome.org/Accessibility/BonoboDeprecation.  Related to this 
work, support is also being added to Qt to make it participate in the 
AT-SPI infrastructure.

We expect the AT-SPI/D-Bus work to be complete by GNOME 3.0, and the Qt 
support should (hopefully) be done in the same timeframe.
