Event processing in GUI

There are events fired by user interface and fired by game model. Events are dispatched by com.google.common.eventbus.EventBus. In class org.microcol.gui.event.modelModelListenerImpl are handled events from model process like:

@Override
public void onTurnStarted(final TurnStartedEvent event) {
    eventBus.post(event);
}

Events from game model are send to user interface. Anywhere in user interface code event could be consumed like:

@Subscribe
private void onTurnStarted(final TurnStartedEvent event) {
        // Do something
} 

When Class that wants to consume some event have be to marked with annotation org.microcol.gui.util.Listener:

import org.microcol.gui.util.Listener;
 
@Listener
public final class TurnStartedListener {
}

Events produced on user interface are directly inserted to EventBus instance. Thread that post event also handle the event.

Model

First not working attempt

Originally was model meant as single threaded. It quickly led to problem like this:

It's clear that it's not working because sequence of events is broken. Event that on turn is AI comes to UI after event that on turn is Player.
