Which GWT EventBus should I use?

Question

In the gwt-user.jar there are 2 EventBus interfaces and SimpleEventBus implmentations.

com.google.gwt.event.shared.EventBus and com.google.web.bindery

Answer 1

I know this question has already an answer but might be worth while adding the following. As I said in my comment above, Activity still needs the com.google.gwt.event.shared.EventBus class. To avoid deprecated warnings, I did the following (I use GIN):

public class GinClientModule extends AbstractGinModule {

    @Override
    protected void configure() {
        bind(EventBus.class).to(SimpleEventBus.class).in(Singleton.class);
        ...
    }

    @Provides
    @Singleton
    public com.google.gwt.event.shared.EventBus adjustEventBus(
            EventBus busBindery) {
        return (com.google.gwt.event.shared.EventBus) busBindery;
    }

...

By doing this, you will always be using the object from the "new" version of Event bus in the bindery package.
