Re: [orca-list] Roundcube mail possibly accessibility of other rich web apps



Hello,

Yes, I think I might try doing that.

How do you think it should look like? Should that be a wiki article a part of the orca documentation or a blog article?

I think it's very intuitive but I'll try writing something anyway because I think it's more than adequate to give something in return for these great enhancements you are adding to orca all the time.

Greetings

Peter

Hey Peter.

Thanks for testing! Any chance you could start drafting a how-to guide
on using Roundcube with Orca? (Yeah, I know, if you asked me to do the
same I'd laugh and make a snarky comment about my copious spare time.
You should feel free to laugh at me and make snarky comments and say
"no." Seriously.) But if you do at some point have some spare time, this
would be some nice documentation to have.

Hello,
This is more than awesome. This must be magic. To make that table
reporting when in focus mode it appears you have just added
_generateTableCellRow() into the speach and braille generator. For less
experienced developer that would be a difficult task.

The follow up commit where you are fixing focus mode widgets irons all
nits I was able to find while using Roundcube. Now this is fully
accessible and very predictable to work with. For anyone dealing with
huge mailboxes, relying on imap search I definatelly recommend giving
Roundcube with Orca and Firefox a try. Address book and settings are
also all fully accessible.

When coupled with other fixes you have done today I think it potentialy
contributes to even more awesome experience with other rich web apps.

There is one worth noting feature still missing at the Roundcube side of
things. Multiselection capability of email messages list is not yet
communicated via ARIA markup and supporting javascript code.

    Hi again Peter.

    Orca master now treats the descendants of menus and toolbars as focus
    mode widgets. Hopefully that will address the other problem you
    reported. Please let me know. Thanks!
