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:

Orca Orca Debugging

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
Application::Id is read/write - implement properly
Test apps with >1 window
Make special keys for Orca work (flat review)

When do we need to create component?
why do menus not get actions?
DEC: for flat review, get it to work
