When you're chatting with someone, you're alerted when that person starts typing, goes away, etc. by a change in the appearance of the page tab which contains the person's id. If you see a keyboard, it means he/she is typing; if you see a yellow chat bubble, it means he/she is away; etc.

When this occurs, a couple of events seem to be emitted by the accessible associated with that page tab:

* object:property-change:accessible-name
* object:visible-data-changed

I believe that I can reliably use those events as a way to detect a status change. However, I am not seeing anything which tells me what the status has changed to. As a result, the status changes are inaccessible to users who are blind.  If you could expose the new status as the description of the AtkObject, that would be awesome.

I'm afraid I've not yet had time to get familiar with your code to try this (sorry!), but here's what in theory should work: When you're changing the icon to reflect the status change, also

* Get the accessible AtkObject for the page tab widget via
  gtk_widget_get_accessible()
* Set the description on that object via atk_object_set_description()

That should do it....

I'd ask that the string you use for the description not be localized. The reason being that some users might only be interested in, say, the typing status.

Thank you *very* much in advance for taking a look at this issue.
