There are 2 pre-requisites to provide an accessible Dash, being:
1/ keyboard navigation support
2/ nux accessibility classes

#1 is implemented and was released as part of alpha-3
#2 is implemented as well, and is used to provide accessibility for the launcher

The missing part is to connect the keyb. navigation and focus change signals to the same atk infrastructure that is now built into Unity.

This bug also serves to track a Feature Freeze Exception request. The request itself will be effective once the missing integration is ready for release into a subsequent Unity point release.

I have just relate this bug to a branch. Anyway, in order to work well with orca, it requires this two bugs fixes:

https://bugzilla.gnome.org/show_bug.cgi?id=657732
https://bugzilla.gnome.org/show_bug.cgi?id=657646

The big problem here is that we are really long away from the oneiric feature freeze.

In the case of accessibility not enabled, this branch doesn't affects at all. It is true that the branch adds some new methods on Unity code, but all of them are just exposing some internal labels, doesn't add new logic.

And in relation of the accessibiliity (ATK) objects, you can find here some code extracts:

  if (unity_a11y_initialized() == TRUE)
  {
    AtkObject* atk_obj = NULL;

    atk_obj = unity_util_accessible_add_window(self->dashController->window());

    atk_object_set_name(atk_obj, _("Dash"));
  }

This is the example of the Dash, but also applies to the launcher and the home panel. Without accessibility enabled no accessible object is created, so no signals, connections and so on.

The tricky part would be with accessibility enabled as there were a lot of changes and there isn't too much time to test it. Most of the accessible object are just a proxy of the base objects, with some signal connections, and with several NULL checks. But as I said there are a lot of changes and new objects there.

I will debate with Unity developers if it is worth to propose the branch to be merged, or should be postponed to next official release. In the second case, my plan would be create a specific unity a11y PPA so it could be properly tested by the users.
