A little improvement:
public class MyWidget extends Composite {
interface MyWidgetUiBinder extends UiBinder<Widget, MyWidget> {
}
private final EventBus bus;
@UiField
private HTMLPanel outerPanel;
@Inject
public MyWidget(MyWidgetUiBinder uiBinder, EventBus bus) {
this.bus = bus;
initWidget(uiBinder.createAndBindUi(this));
}
}
