I wrote this some time ago and didn’t
get a new response.
Any idea of what I can do to have Voice
Over focus stop on my custom controls? (And an image if possible)

controls
My controls are handling the
kEventSetFocusPart event by setting an internal flag and returning their custom
value in the output parameter (noErr is the returned value for the handler). On
draw, the flag is checked to see if the selection highlight needs to be drawn.
I think this is the right way to do it, isn't it?
I am not intercepting tab keys.
I tried calling
AXNotificationHIObjectNotify to send a kAXFocusedUIElementChangedNotification,
but nothing changed.

I believe Voice Over is reacting to
kAXFocusedUIElementChangedNotification.
I would guess that notification isn't being sent for your custom
controls.
The Control Manager should send that out appropriately for custom
controls, though. How are your custom controls implemented? Do they react to
the kEventControlSetFocusPart event appropriately? Are you intercepting the tab
key and driving your own focus loop?

I have a Carbon application showing a non-composite
dialog with some custom controls. I am trying to make Voice Over read those

I noticed that even when I can tab to my custom controls and
I can use an accessibility inspector and see all the attributes, the Voice
Over focus (black rectangle) does not stop on them. It just remains in the
previous control.
Is there any property or accessibility attribute I need to
set to make them work like regular controls for voice over?
It probably does not matter, but just in case one of my
controls is a custom databrowser (elements are accessibility objects, not
actual controls). The other is a custom tab control (each tab button is a
control).
Additionally. I have a Picture Control on that same dialog.
I'd like Voice Over to read a description of the picture when tabbing to it.
However, I cannot get this to work since the Picture Control never takes focus.
Is there any way around this?
