Initial accessible object:state-changed:focused event missing from password field when unlocking screen

[joanmarie]

Steps to reproduce:

1. Acquire Orca from its main branch (see notes below)
2. Run the unstable version of Orca in a MATE session
3. Lock the screen and unlock it

Expected results: Orca would announce the password field.

Actual results: Orca only announces a panel.

Notes:

• The reason why Orca stable doesn't have this bug is that it listens for the focus: event. That event was deprecated over 10 years ago. I (the Orca maintainer) am no longer listening for that event; object:state-changed:focused is expected.
• When you perform the steps to reproduce the problem, the correct event (object:state-changed:focused) is emitted, BUT it's emitted on a panel -- presumably the ancestor of the password field. The password field only emits focus: initially.
• If you Tab away from the password field and Shift+Tab back to it, the correct object:state-changed:focused event is fired by the password field and Orca presents it.
• This is probably a Gtk bug. See https://gitlab.gnome.org/GNOME/gtk/-/issues/454.

@cwendling: Here's another, please and thank you very much!!

This appears to be fixed by https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/7239. Let's hope that lands and lands soon!

I can't really get an Orca master running just yet here, but adjusting the listener from mate-desktop/caja#1778 I get:

GTK 3.24.38

[window | ] is now focused (focus:)
[panel | ] is now focused (object:state-changed:focused)
[password text | ] is now focused (focus:)

GTK 3.24.42

[window | ] is now focused (object:state-changed:focused)
[window | ] is now focused (object:state-changed:focused)
[panel | ] is now focused (object:state-changed:focused)
[password text | ] is now focused (object:state-changed:focused)
[window | ] is now focused (object:state-changed:focused)

So it looks a bit spammy good (the first even actually happens earlier, likely when locking the screen), but and might be fixed. The last event could look a bit worrying, but it seems to actually happen after unlocking (well, after having hit Return at least), so shouldn't be a problem.

So I'd say this is fixed by upgrading GTK.

Cool! @cwendling: Do you happen to know where the duplicates (which, again, I'm not worried about) are coming from?

[cwendling]

@joanmarie here I actually edited my post because there isn't really any duplicate, the first event seem to happen right after when locking (so I guess the black locking window gets active), and I believe the second one is either the unlock dialog or just the same window getting active again because of user interaction. Anyway, those don't seem to be duplicates I think.
