Bug Description

As usual, normally accessibility tools are not poking the apps about his status, it reacts to the accessibility framework events.

Right now there is missing the emission of children added/removed on any container. This leads to some missing accessibility objects on the hierarchy, so the accessibility tools doesn't get the proper events from unity.

I have just uploaded the branch lp:~apinheiro/unity/a11y-emit-children-changed

It doesn't emit that signal for all the accessibility object, specifically:

  * NuxViewAccessible
  * NuxLayoutAccessible

But this is because nux::View and nux::Layout lacks signals reporting that a child was added.

Anyway, this branch emit "children-changed" for the most important object, the root, and I found that no manual request of the object was required (so no accessible objects are missing).

So I suggest to close this bug once this branch gets merged, and managed those objects in a different bug.
