Re: GWT JS Interopt

I have the same problem with addEventListener, the generated code is not exactly as you mention: 

This is my code:

    public interface EventListener<E extends JsObject> {

        void onEvent(E event);

    }

    @JsType(prototype = "HTMLElement")

    public interface HTMLElement extends Element {

        public void setAttribute(String align, String center);

        public void appendChild(HTMLElement element);

        public void addEventListener(String event, EventListener<? extends JsObject> handler);

        @JsProperty

        public void setInnerHTML(String text);

        @JsProperty

        public void setInnerText(String text);

    }

    .....

    HTMLElement button = doc.createElement("button");

    .....

    .....

    button.setInnerText("UPDATE - See the console");

    button.addEventListener("click", new EventListener<JsObject>() {

            @Override

            public void onEvent(JsObject event) {

                window().getConsole().log(event);

            }

    });

    ....

    ....

    ....

    body.appendChild(button);

    .....

    ....

This is the generated code:

 _.onModuleLoad = function() {

  var body_0, button, div, input_0, observer, p, person;

  body_0 = $wnd.document;

  div = body_0.createElement("DIV");

  p = body_0.createElement("P");

  input_0 = body_0.createElement("input");

  button = body_0.createElement("button");

  body_0 = $wnd.document.body;

  person = new clgscm$Person;

  observer = new $wnd.PathObserver(person, "name");

  input_0.bind("value", observer);

  person.name = "Cristian";

  button.innerText = "UPDATE - See the console";

  button.addEventListener("click", new clgsc$gwt_sample$01(this));

  $wnd.console.log("%cWelcome to JSInterop!%c", initValues(jl$getClassLiteralForArray_0(cggl$Ljava_lang_String_2_classLit, 1), $intern_2, 2, 4, ["font-size:1.5em;color:#4558c9;", "color:#d61a7f;font-size:1em;"]));

  div.appendChild(p);

  div.appendChild(input_0);

  body_0.appendChild(div);

  body_0.appendChild(button);

};

createForClass(61, cggl$Ljava_lang_Object_2_classLit);

function clgsc$gwt_sample$01(this$0) {

  this.this$01 = this$0;

  jl$$0init__V__devirtual$0(this);

}

Any Suggestion?

Thanks!!!

Yes, i didn't use addEventListener. But i has a similar usage:

Java

Bus.subscribe(String topic, Handler<? extends Message> handler);

translated to js

bus.subscribe("some/topic", function(message) {    var body = message.body();    console.log("Name: " + body.name);  });

A bonus issue, I saw you did not use addEventListener like the demo does, and I really struggled to make it work.  The generated javascript looks like "addEventListener('click', new xxx(this))" which doesn't work (the key thing here being "new" I'd guess).  I found no other way to call it directly and eventually resorted to doing it from a jsni function instead:

        public static native void jsAddEventListener(Element elem, String event, EventListener listener) /*-{

elem.addEventListener(event, function(ev) { listener.onEvent(ev); });

        }-*/;

Which demo uses addEventListener?
