When does changing the 'Enable Access for Assistive devices' preference
actually take effect?
I'll write up a bug for us to clarify this issue.
FYI. I am not explicitly constantly calling AXAPIEnabled, I just let
my code
try doing what I want and let it cope with kAXErrorAPIDisabled
(obviously I
don't let it do anything if the APIs are not actually there (pre OS X
10.2)
If AXAPIEnabled is out of sync with the preference, that would be a bug
you
should report.
Assuming that they are supposed to become unusable straight away, will
my
app get any observer notifications of elements being destroyed?
No you won't. The UIElements aren't really destroyed, so a destroyed
notification isn't quite appropriate. In fact, since accessibility has
been turned off - the notification mechanism itself shouldn't be in
operation anymore.
If this is important to you, you can file a feature request.
