Offhand, a couple notable clients are AppleScript and Dictionary.

Arrrr, the only problem is that you cannot get to preference only when
accessibility access is switched on, for apple script.

What are the other accessibility API clients, you mean by

Thanks
Mark.

The issue here is the assumption that VO is the S/W calling the
accessibility APIs.  There are actually numerous other accessibility
API clients within the system, affecting all users, not just those
who have difficulty seeing.

Your best bet may be a preference pane/control panel.

Hi All,
  I'm trying to work around a problem with Voice-over technology
that you
cannot detect whether or not it switched on, doesn't sound like a
big issue,
but we have voice over capability within our webkit application and it
work's well, but if the user has switched on Voice-over for their
system
then they get 2 talking system which is very confusing for them.

So I'm wondering if I declare my own control inheriting from the Web
control, then I could just overload a few method which the
accessibility
API's called, then hopefully assume if something is calling this
methods
then Voice-over capability must be switched on ? - How does that
sound.

  The plan is if we detect the Voice-over is switched on then we
will shut
down ours and let them use the OS's.

  I don't have any experience of these accessibility API's although
I did
sit on a WWDC Session, and seem ok but that always the case until
you get
down to it.

  Anybody got insights on this.

Thanks in advance
Mark.
