Inject your eventBus in to the widget, it will work just fine, then "new"
your widget or create it by using injection, or whatever.
You only need <ui:with> if you need to access some object in the ui.xml file
that you want to be constructed somewhere else. Typically this is some
object that get injected in to the ui.xml associated .java class or it is a
Resources object (typically also injected).
Example:
public class MyWidget extends Composite {
private static MyWidgetUiBinder uiBinder =
GWT.create(MyWidgetBinder.class);
interface MyWidgetUiBinder extends UiBinder<Widget, MyWidget> {
}
private final EventBus bus;
@UiField
private HTMLPanel outerPanel;
@Inject
public MyWidget(EventBus bus) {
this.bus = bus;
initWidget(uiBinder.createAndBindUi(this));
}
}
