Subject: [PATCH] core: Change MetaWaylandTextInput event forwarding to IMs
|
||||||
|
|
||||||
|
We need to juggle with some things here to keep key event ordering
|
||||||
|
and accounting consistent.
|
||||||
|
|
||||||
|
The keyboard internal state changes (and maybe modifier event emission)
|
||||||
|
happening through meta_wayland_seat_update() should ideally happen
|
||||||
|
from the same key events that reach the client through wl_keyboard.key,
|
||||||
|
so that wl_keyboard.modifier events are emitted in the right relative
|
||||||
|
order to other key events.
|
||||||
|
|
||||||
|
In order to fix this, we need to decide at an earlier point whether
|
||||||
|
the event will get processed through IM (and maybe be reinjected),
|
||||||
|
thus ignored in wait of IM-postprocessed events.
|
||||||
|
|
||||||
|
This means we pay less attention to whether events are first-hand
|
||||||
|
hardware events for some things and go with the event that does
|
||||||
|
eventually reach to us (hardware or IM).
|
||||||
|

||||||
