It has been suggested to me that a more appropriate/consistent use
of the focused UI element concept for menus would be for the menu
itself to be the focused element, and that therefore, the Menu
Manager should only send this notification when the selected menu
changes, and not when the selected menu item changes.
I'd like to know if any accessibility client apps are currently
using this notification in the context of menu selections, and would
be affected by this change. You can either respond to the list or
respond to me privately.
I have not needed the notification mechanisms yet so please correct
me if I make a stupid remark, but I would say that even if the
current method may be theoretically less correct (though that depends
on how you define the "focus" concept) it would seem to me that it is
more powerful then if there would be only notifications if the menu
itself changes. I mean, in the current situation it should be
relatively easy for the accessibility app to figure out after a
notification for a menu item focus change that the item belongs to
the same menu so that the "focused" menu has not really changed. In
the alternative situation knowing that the "focused" menu changes is
easier, but there will no longer be a way to get notified if the
"focused" menu item changed. That would seem like a set back to me.
But, again please correct me if I merely misunderstand the issue.
