Pete,

I am looking at accessibleDocument. Should we not do more than that for a document interface? Should we also have features to collect and access specific objects with a specific element type - filtering mechanisms?

Hi Rich, It's been a long time since I looked at accessibleDocument.  (It's not part of IA2.)  I couldn't find a link in my archives.  Please send it.  Would that discussion be better held on the parent LF a11y list at accessibil...@lists.linux-foundation.org ?  That will also be of interest to the Linux a11y architects.


Note: I am in favor of not unnecessarily growing the API. API changes cause a lot of churn. However, with the FCC adopting creating new laws based on the 21st Century Communication and Video act there is a need for infrastructure to better support the HTML 5 changes Silvia is working on to support video and audio.

I am looking at the notification mechanism for media MEDIA_TEXT_QUEUE_CHANGE. Would it be better to have a callback registry for ATs similar to what we did in Java? I am concerned about potential OS scheduling issues caused by posting events to the message queue.

We've talked about adding something to get around the limitations of WinEvent, primarily the lack of an event payload so out of process AT don't have to use (and possibly get stale data) on a following call fetching event data.  It's not become enough of an issue that the group has pushed that change through though.

For in process AT the callback happens on the same thread that fires the event.  Jamie might be able to comment on what problems there might be for out of process AT when handing a cue change event.

    Hi, Jamie. I missed Mick suggestion on the list. It's sounds reasonable and I agree we should try it before getting new API for this since the issue is mostly about events.

    Thank you.
    Alex.

      Hi.

      Nice work; good to get the discussion going. :)

      I still don't see a need for this registry API. Why not just use IsWinEventHookInstalled(), as Mick suggested on the IA2 list?

      Thanks.

      Jamie
