I'm trying to bind a GWT view with its presentation layer, but it doesn't seem to be doing anything.
It's a Spring Roo GWT generated project and I'm trying to use the scaffold given as far as possible. The view is a simple button (R.ui.xml) and the rest of the view is defined in R.java:
public class R extends Composite implements RPresenter.Display {
interface MyUiBinder extends UiBinder<Widget, R> {}
private static MyUiBinder uiBinder = GWT.create(MyUiBinder.class);
@UiField Button myButton;
private ClickHandler buttonClickHandler = null;
public R(){
initWidget(uiBinder.createAndBindUi(this));
}
@UiHandler("myButton")
void onButtonClick(ClickEvent event){
GWT.log('Button clicked');
if (buttonClickHandler != null){
GWT.log("buttonClickHandler event triggered");
buttonClickHandler.onClick(event);
}
}
@Override
public void setButtonClickHandler(ClickHandler buttonClickHandler) {
GWT.log("setButtonClickHandler");
this.buttonClickHandler = buttonClickHandler;
}
}
The presenter:
public class RPresenter {
public interface Display extends IsWidget {
void setButtonClickHandler(ClickHandler buttonClickHandler);
}
private final Display display;
private final EventBus eventBus;
@Inject
public RPresenter(EventBus eventBus, Display display){
this.display = display;
this.eventBus = eventBus;
bind();
}
private void bind(){
display.setButtonClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
GWT.log("onClick event triggered");
}
});
}
public void go(HasWidgets container){
container.add(display.asWidget());
}
}
And for my GIN module I use the generated ScaffoldModule in the ...client.scaffold.ioc package:
public class ScaffoldModule extends AbstractGinModule {
@Override
protected void configure() {
GWT.log("ScaffoldModule configure");
bind(EventBus.class).to(SimpleEventBus.class).in(Singleton.class);
bind(ApplicationRequestFactory.class).toProvider(RequestFactoryProvider.class).in(Singleton.class);
bind(PlaceController.class).toProvider(PlaceControllerProvider.class).in(Singleton.class);
//bind(RPresenter.Display.class).to(R.class).in(Singleton.class);
bind(RPresenter.Display.class).to(R.class);
}
static class PlaceControllerProvider implements Provider<PlaceController> {
private final EventBus eventBus;
@Inject
public PlaceControllerProvider(EventBus eventBus) {
this.eventBus = eventBus;
}
public PlaceController get() {
return new PlaceController(eventBus);
}
}
static class RequestFactoryProvider implements Provider<ApplicationRequestFactory> {
private final EventBus eventBus;
@Inject
public RequestFactoryProvider(EventBus eventBus) {
this.eventBus = eventBus;
}
public ApplicationRequestFactory get() {
ApplicationRequestFactory requestFactory = GWT.create(ApplicationRequestFactory.class);
requestFactory.initialize(eventBus);
return requestFactory;
}
}
}
In the GWT development mode console, the "ScaffoldModule configure" never displays, yet the generated scaffold seems to binding just fine as the events get passed along from component to component without a hitch, unless the binding is magically happening somewhere else and that is dead code.
When I put my bind(RPresenter.Display.class).to(R.class) in, it doesn't seem to do the binding. The only output I get in the GWT console is "Button clicked" which is called in the view and then nothing further. I'm clearly missing something, any ideas?
