hum... that works... usage would be something like?
efl_event_callback_call(event_type_obj, EFL_LOOP_EVENT_TRIGGERED, data);
(that would make event dispatch synchronous), or:
efl_loop_broadcast(loop, MY_EVENT_CLASS, data);
which internally will queue {MY_EVENT_CLASS->data} and call
efl_event_callback_call() at some specific main loop phase like
before.
I'd not oppose as it will simplify the logic a lot, basically you
don't need to do anything at all -- all done by Eo. Including
"walking/delete_me" logic...
then each loop contains a hash cls -> instance, return the instance
(event_type_obj) or create and return for the first time.
in that case, just be aware that MY_EVENT_CLASS for legacy is a single
one: ECORE_EVENT_LEGACY_CLASS. It will contain "legacy_type: int"
property, which uses the global integers to work on. Then
ecore_event_callback_add() will connect efl_event_callback_call()
using a proxy/wrapper, that will filter by "legacy_type", converting
to the old dispatch system -- those globals still remain.
