Since controlPanel is presumably an instance variable of the
ObserverSwarm, have you thought about passing the agent a pointer
to the panel and then execute the doTkEvents? Alternatively you
could pass a pointer to ObserverSwarm to the agent and then put
this method in ObserverSwarm:

-updateGUI {
        [controlPanel doTkEvents];
        return self;
}

and then in the agent you simply say:

        [observerSwarm updateGUI];

where observerSwarm is the name of the instance variable that
points to ObserverSwarm.

I have taken to passing the pointer to ObserverSwarm to ModelSwarm
when I call buildObjects (assuming that you have main.m create
ObserverSwarm, and ObserverSwarm create ModelSwarm) i.e. instead of

        [modelSwarm buildObjects]

ObserverSwarm calls:

        [modelSwarm buildObjects: self]

and now you can have modelSwarm pass the pointer to ObserverSwarm
to any object in the model that needs this info. (Of course you have
to define the buildObjects: method in ModelSwarm.)
