Thanks for that, will check it out.
The carbon apis are no longer supported by apple,
Has apple anounced that?
Repeatedly. They're encouraging all developers to use the cocoa
apis, because of the tighter integration to the system, and future
upgrades and so forth.
and it would be nice to
have cocoa apis supported, because of their better integration to the
system, and their accessibility features that are basically free
when used
properly.
what do you mean by "accessibility features"?
Voiceover (the screen reader that ships with osx) and the other
accessibility features such as reading outloud, screen contrast,
larger/smaller text, background/foreground colors and so on) are all
basically free when using cocoa apis, as the features are built-in to
the cocoa apis, and require very little (if any) coding on the
developers part to make the programs usable by users of these
technologies.
Being a voiceover user myself, I'm of course all for this modification.
Carbon aps can be made accessible, but it takes additional work on the
developers part, and generally, they're still a bit more difficult to
use (I.E. vo users need to use simulated mouse clicks instead of using
voiceover generated button clicks) as well as labels for things like
buttons, tables and scroll bars. All these things are much simpler
under cocoa than they ae using carbon equivalents.

As opposed to the one for cocoa at:

There's considerably less work to access enable a cocoa app then there
is for a carbon one, as evidenced by comparisons between these two
document trails.
On the surface, it looks similar, but do some digging, and you'll see
there's a world of difference.
A lot of things you get for free with cocoa takes specific coding on
the carbon apis.
That's why I'm trying for cocoa support (preferrably by default) as
that would make more apps accessible right out of the box.
