In pyatspi2, Registry.setReferenceWIndow() is misspelled. However,
that function is never called in Orca or elsewhere, as far as I can
tell.
This ties down to atspi_registry_set_reference_window(), which just
calls _atspi_mutter_set_reference_window(). The side effect of that
is to set the ATSPI_MUTTER_DATA.window_id and
window_id_is_explicit, but again, those fields never get used in the
atspi-mutter.c code. I think they were meant to be used in
_atspi_mutter_generate_keyboard_event or
_atspi_mutter_generate_mouse_event.
Relatedly, _atspi_mutter_generate_keyboard_event takes a
keystring argument but it’s not used.
What is incomplete here?
While the device event controller (DEC) code works for X11, it doesn’t work for Wayland because there are no hooks there to sniff the keyboard or mouse.
However, the machinery to synthesize events is presumably still useful. I’d like to be able to add tests for it.
