We are happy to give you a release of the Qt Accessiblity bridge for Linux. The bridge provides the platform integration with the platform's accessibility interface. It is still tagged as alpha but works surprisingly well here, so we'd like to get feedback from you.
The biggest change compared to earlier version is improvements in the way DBus is used. This leads to huge improvements when it comes to memory and cpu.
In order to play nice and make Qt applications accessible we chose to implement AT-SPI2 which is used by GNOME so that Qt, KDE and GNOME applications will be accessible in the same way with the same tools. The first goal is to get a nice experience with Orca, the GNOME screen reader.
Get it: You need a working AT-SPI2 stack on your distro of choice. Chances are that there are packages. You probably need packages like at-spi2-core, at-spi2-atk, python-pyatspi2 and Orca (screen reader).
It may be required to tell GNOME to switch over to using at-spi2 instead of 1. gconftool-2 --set /desktop/gnome/interface/at-spi-dbus --type bool true gconftool-2 --set /desktop/gnome/interface/at-spi-corba --type bool false
For GNOME apps to be accessible you may need: export GTK_MODULES=gail:atk-bridge
