Hello all,
this is a pretty simple issue, but one that has kept me a bit confused.
How does the OS, or a third-party application such as VoiceOver get
the first accessible object (from which it starts its traversal of
the accessibility object hierarchy, I assume)?
Obviously, one can implement the Accessibility protocol on any
NSView, but from what I've read in the archives and in some of the
source code examples, a normal technique is also to implement another
abstract object to delegate everything to. The question is, what
does that object have to hook up to, so it is visible for third-parties?
Thanks,
Håkan
