There has been a proposal to have desktop environments implement a D-Bus API that accessibility tools like Orca can use to check and turn on/off accessibility. We already have a "Enable assistive technologies" check button in the accessibility settings dialog. However, blind users will have a hard time to find this button when a11y is disabled. If we implement the D-Bus API in xfsettingsd, enabling a11y would be as simple as launching Orca. | There has been a proposal for a D-Bus property to synchronize the setting that says whether assistive technologies are enabled across applications and desktop environments. We already have a "Enable assistive technologies" check button in the accessibility settings dialog. All we have to do is set the ''org.a11y.status.IsEnabled'' property on startup and update our setting whenever the this property changes. This will allow applications like Orca to enable AT support in Xfce automatically. That way blind users can just start Orca--followed by a logout/login--to activate AT, rather than having to search for the "Enable assistive technologies" check button. |

| ==== Notes ==== |
| |
| The D-Bus API proposed in the mails is outdated. at-spi2-core implements the following API instead (see http://git.gnome.org/browse/at-spi2-core/tree/bus/at-spi-bus-launcher.c#n60): |
| <code> |
| <interface name='org.a11y.Status'> |
| <property name='IsEnabled' type='b' access='readwrite'/> |
| </interface> |
| </code> |
