[easel] Re: [gme-users] Invoking runComponent from GME Addon.

[Larry Howard]

Jonathan,

The issue here has transitioned to invoking a component from within an
event-based AddOn.  The problem, conceptually, is that AddOns are invoked in
a late phase of transaction-processing.  The context is really very wrong
for component invocation, since components are themselves transaction-based.

The possibility for externally generating events has been addressed already
in the affirmative.  There are some issues of communicating
application-specific data for the event from an external source, and Peter
has provided a functional (if somewhat tortured) workaround.

It might be better if Daniel were to tell us more about the "what" without
choosing yet a "how".  For example, just as it is possible to invoke an
AddOn externally, by generating a global or object event, it is possible to
invoke a model interpreter externally.  Perhaps the external entity should
be orchestrating.  I don't know because I don't know what Daniel is trying
to accomplish.

Peter,

Is this a possible enhancement to GME? It seems like if the AddOn is running
and waiting for events that there should be *some* way to send an event
externally...after all, the mouse can do it. ;) 

Daniel, 

Maybe for demo purposes we can just have a special interpreter that does
this interfacing (read: generate the event which the addon is listening
for...) and work with Peter to figure out how to generate this through
visual studio's editor later?

I'm a little spotty following this conversation, I'll try to catch up on the
thread this evening....

Jonathan
