Thanks for ur advise.
How about if i define a interface ( View Listener ), then my presenter
implement the View Listener?
Example :
public class MyView extend Composite implement MyPresenter.View {
public interface Listerner {
public void onEdit(String id);
}
.....
.....
Listener listener;
// a List of Button here
button.addClickHandler(new ClickHandler(){
public void onClick(ClickEvent event){
listener.onEdit(id);
}
);
}
public class MyPresenter implement MyView.Listener {
public interface View {
}
public void onEdit(String id){
// Do something here.
};
}
Please correct me if i am following the wrong way.
Thanks.
