Orca doesn't report that the Launcher receives the focus

Bug Description


1. Be sure that the accessibility is enabled and orca running
2. Press Alt+F1 to give the focus to the Launcher and start the keynav mode on Launcher


Orca speech out that the Launcher receives the Focus, and the current icon selected


Orca just speech out the selection change


It is true that it gets exposed the item selected, but it can be somewhat misleading without the context of being on the Launcher (and in some cases, as I explain on bug 727131, the icon could not have any name, so the selection would not be exposed)

As of unity 3.6.4, i.e current unity trunk, revision 945, this is still not working. I enabled Orca's debugging, but couldn't find anything substancial there. I then monitored window, object, and focus events in accerciser, and when pressing Alt + F1, there are no window activate/focus change events from Unity. There were however, object property change events, with the accessible name being changed to the menu titles of nautilus on the desktop, before several events of object property state defunct messages.

To be clear, here are the steps to reproduce:
1. Open accerciser
2. Go to the event monitor tab
3. IF monitoring is currently enabled, disable it, and clear the buffer.
4. In the right table, check window, focus, and object. Leave the radio button option set to everything.
5. Start monitoring, and attempt to move focus to the launcher, with Alt + F1.

You will get the above described events in the event monitor, with no focus events.

I think that the problem is this bug:


Due this bugs, sometimes it is required a manual atk object exploration in order to have the proper accessible objects (so the signals related).

While solving this bug I didn't notice it because I usually checked that the accessible object hierarchy was there manually. After that I started to notice missing events without this manual exploration, so I reported that bug.

I'm working on it, so this would be solved soon.

Note: IMHO, we shouldn't re-open this bug. If the accessible object hierarchy are there, things work fine.

Thanks for the review
