Re: [orca-list] ORCA improvements

[Bill Cox <waywardgeek gmail com>]

Actually, the most important bugs in Orca tend to get fixed pretty
quick by the Orca guys, but with the loss of Willie as a full-time
Orca guy, there's lots of places in Orca that may need help.  I'm sure
Joanmarie will know.  I don't muck with Orca code much, because the
most important bugs are more often in non-Orca packages, and the Orca
guys have kept their code pretty clean.

If you're able to help edit code throughout the Linux system, I
suspect you will find tons of work that needs doing.  Regardless, I'd
be happy to help as far as non-Orca code goes, like with Voxin
integration, which is more of a speech-dispatcher thing.  Here's a
list of Orca/Linux issues I'm interested in:

Bugs
----

Deal with Firefox/Orca problems.  Firefox rewrote the caret navigation
and it has bugs that make
structural navigation with Orca difficult.  The bug report is at
https://bugzilla.mozilla.org/show_bug.cgi?id=546068
We have a patch that fixes this problem, but currently it causes two
Mozilla test cases to fail.

Fix voxin problems on 64-bit Ubuntu Lucid.  We use it with
speech-dispatcher, but the voice is garbled for some reason, only on
64-bit.

Fix usb-creator-gtk.  Currently any Python application that updates
it's widgets with a thread locks up the system if Orca is running.  I
believe this is a bug in atk-spi-registryd, and effects several other
programs as well.

Make icons in icon tray say their names instead of just "icon".  There
is a title property that seems to be read by Braille, but not spoken.

Figure out why Orca is not reading upper case chars in a higher pitch.
 There's some problem in the Orca/speech-dispatcher interface.

Improve accessibility of GTK+ TreeViews.  Currently apps using
TreeModelSorted, TreeModelFiltered,
or CellRendererPixbuf are typically not accessible, as these classes
break the accessibility
model.  We have a patch for this we're testing in Vinux, and a bug
filed with GTK+: https://bugzilla.gnome.org/show_bug.cgi?id=617629

Fix GTK+ so that we can do first-letter navigation in combo boxes.
This would help sighted users, too, but is especially hard on Orca
users.

Improve thunderbird list views - we should not be loading everything
at once when orca is running.  So, for example, clicking on trash
takes several minutes to respond.

New Features
------------

Make evince accessible.  We need a PDF solution with Orca.

Add "read to file" capability to Orca, which needs a speech-dispatcher
upgrade to return synthesized speech rather than just play it.

Thanks for helping out!
Bill
