Hello,
You need to use @JsFunction, something like that would do the trick in your
case:
@JsFunction
public interface Function{
public JavaScriptObject call(FBResponse event);
}
and then you can define your FBResponse either using JsInterop or JSNI:
@JsType(isNative=true, namespace=GLOBAL, name="Object")
public interface FBResponse{
public int status;
}
