Is kAXFocusedUIElementChangedNotification intended for such purposes?
No. This notifications tells you when the keyboard focus has changed.
If not, is there a way how to find out that the VO cursor has moved?
No. You can file a feature request, but the VO cursor is a concept
specific to the Voice Over application and I doubt they are planning
to expose it.
I don't know what your needs are, but the VO cursor is built on top
of the public accessibility APIs. You should be able to do the same.
I've just noticed that descriptions in my app that are entered as
"A-D", "E-J" are improperly read. Do I have to set descriptions to
"ay to dee" or "ee to jay" instead of nice "A-D" to achieve proper
reading?
Can be role descriptions and element descriptions shown somewhere
or are just for reading purposes so it would be OK to do what I do?
Is there some alternative to get "A-D" properly read?
AXDecriptions are supposed to be regular text (not phonetic). Voice
Over does "read" the AXDescriptions, but other accessibility apps
treat them as text.
That being said, I don't think it would be unreasonable for a button
labeled "n-m" to have a description that was "n to m" or even "en to
em". Note - I picked the letters "n" and "m" because those are among
the few letters whose name I know how to spell (thanks to playing
scrabble).
There is definitely precedent for this. I would consider it akin to
having the button text contain an abbreviation and the description
providing the full term. E.g. a natural logarithm button ("ln") would
have a description of "natural log".
Obviously, this doesn't handle every case. A way for assistive apps
to provide phonemes has been discussed, but it puts yet another
burden on apps trying to accessorize themselves.
Go ahead and file a feature request. I'm pretty sure this is already
a bug about this, but it can't hurt to ask again.
