The bridge is a Qt Accessibility plugin that exposes the internals of a Qt application to interested accessibility clients such as screenreaders. AT-SPI on D-Bus at Linuxfoundation The source code for the bridge can be found here: Qt AT-SPI on gitorious Tools With the Gnome efforts to implement AT-SPI 2 we have some really helpful tools: Accerciser accerciser manual Orca Orca Debugging Tutorial on techbase Python Testing/Development You need a very recent environment, most notably: pyatspi2, at-spi2-core and at-spi2-atk Inside a Gnome session the a11y uses a dedicated d-bus. So if you want to monitor what is going on, you should use: dbus-monitor --address `xprop -root | grep AT_SPI_BUS | sed -e 's/.*= "//' | sed -e 's/"$//'` Todo Complex widgets with children? Tabs... clicking on a file in qgit (crash fix committed, but still needs proper fix) GetApplicationBusAddress seems not defined in the xml but is actually called mgorse: That ought to be defined in the xml. It is used to try to set up a direct dbus connection between libatspi and the application. libatspi will revert to using the session bus if it returns an empty string or an error don't pretend to be gail, coordinate with orca devels Test apps with >1 window fix action for menus inside qt scroll bars have value interface but don't update and cannot be updated, value interface in general text attributes (bold etc) tabs Widgets Combobox List Tree Table Spinner Scrollbar KDE Widgets Widget Status ExampleWidget1 Ready. ExampleWidget2 Mostly done, still needs fooBar() call.

We can only (safely?) hold on to interfaces created by navigate or queryInterface Interfaces that we get through notifyAccessibility are deleted by Qt behind our back, so we need to never keep those around (Frederik will try to fix that now) Retrieved from "https://community.kde.org/index.php?title=Accessibility/qt-atspi&oldid=12010" Content is available under Creative Commons License SA 4.0 unless otherwise noted.
