I don't understand your example.

It's true there might be problems if you had to find the editor object
in order to ask for events.  But I don't think you'll have to do this.

Instead, I think we'll have a generic Event Manager, which will act as
an "event bus".

Objects that generate interesting events will connect to the manager
and post events.

Objects that want to receive events will connect to the manager and
listen.


We'll use the CORBA Event Service as the core of the event manager.
Basically all of our "additions" will be just convention:

* Conventions for event types.
* Conventions for event naming
* Our service will be located at a particular place in the namespace


Does this make sense?


I can expand on what I think an event ought to be, and why, if anybody
cares.
