Hi all,
I'm a newcomer to this list, the world of accessibility, and to the
world of Mac, so please excuse any foibles :-)
I'm working on a project to enable accessibility in a UI toolkit, and
have come across a situation I don't know how best to handle. In our
toolkit, for historical reasons, we have our list/tree/table/etc
components contain a scrollpane, rather than the perhaps more common
approach of having a scrollpane contain the list/tree/table.
Based on the best of my sleuthing ability, it seems to me that the mac
voice over software will only allow for scrolling (VO+Shift+S, then
up/down) if the AXScrollArea wraps the list, etc. I was able to prove
this by hacking our accessibility code, such that the accessibility
hierarchy in these ui components reports the parent / children
relationship as Mac OS expects it, but that becomes mucky _really_ fast.
It isn't an option to change the hierarchy of our ui components either,
unfortunately.
I was wondering if you accessibility experts had any better advice on
how to enable scrolling in this situation? There is a very high
likelihood that I have overlooked something obvious, and I would really
appreciate it if you could tell me what it is :-)
Thanks,
Jonathan Giles
