SWT is indeed more accessible.   I think the only parts of Libre
Office that are in Java are those tied to the database.  Most of the
code is in c and c++, I heard.  Btw, QT is somewhat supported.  I
wouldn't call it stellar but it's not impossible to navigate witha
jaws cursor.  (Mouse simulator)  Idle, for instance, is in QT.  I dn't
see them rewriting the code to use swt classes though.  Besides, I
think this creates issues in Gnome since swt is less accessible there
than swing.

Hi Alex,

Well, my thinking is and always will be that Libre Office is better
off making itself accessible no matter what screen reader is used.

That is why LibreOffice (like needs to support
accessibility APIs, keyboard access, desktop themes, etcetera. For a
screen reader to work with an application, the application needs to
implement the accessibility API (for example the Java Accessibility
API, which is not tied to a specific operating system), and the
screen reader needs to support that API. As far as I know, screen
readers on Windows have generally weak support for the Java Accessibility

True, although the screen readers for Windows have a weak support for SWING
API. The support for SWT is much better.

But the screen readers for Windows have a non-existent support for other
GUIs like Tk, GTK, QT...

(Note: Java accessibility on Windows requires the Java Access Bridge.
Oracle is working on a new version of this bridge that will be part
of the Java Runtime Environment instead of a separate download.)

This will be great, but hopefully the screen readers manufacturers will also
offer a better support for SWING.

JAWS for Windows offer some support for Java Access Bridge as it is now, but
only in a virtual buffer, so the apps are seen like web pages.

SWING is slower than SWT anyway, and that weak support offered by JAWS makes
the apps much less responsive, but what's the most important for blind
programmers is that it is very hard if impossible to make the design of the
GUI, because in the SWING apps, JAWS doesn't offer that "JAWS cursor" for
allowing us to "see" the position of each window control on the screen.

I heard that Window Eyes started to offer a better support for SWING than
JAWS but I haven't tested it.

By the way, what interface is LibreOffice using? I've tested OpenOffice and
it was pretty accessible although I don't remember if I had Java Access
Bridge installed. Does it use something else than SWING?
