 (for example) contact count and this view needs to know about some changes
 in your contacts, you would fire an event in deleteSelectedContacts.

  Hi everyone, now that i am working with GWT i am facing a problem with
  the event handling mechanism the first problem was (

 http://groups.google.com/group/google-web-toolkit/browse_thread/threa...
  ), but when i read this article MVP II (
 https://developers.google.com/web-toolkit/articles/mvp-architecture-2
  ) - actually i read it several times - i still don't understand when u
  to use EventBus mechanism and when not ? and if i have to use when u
  use EventBus Handler and HandlerManage ?.
  Here is what confuses me:

  public class ContactsPresenter implements Presenter,
  ContactsView.PresenterContactDetails {
  ..
  public void onAddButtonClicked() {
      eventBus.fireEvent(new AddContactEvent());
    }

    public void onDeleteButtonClicked() {
      deleteSelectedContacts();
    }

    public void onItemClicked(ContactDetails contactDetails) {
      eventBus.fireEvent(new EditContactEvent(contactDetails.getId()));
    }

  
  }

  Why one method fires and event and the other just do some logic witch
  is defined the class ?

  Thank you all for your replies.

  the source code of the example is here :
