I'd say that the normal pattern to hande input done in a dialog window would be to have an "OK listener" or "save listener", or in Java 8 just a Consumer of the edited data type.

public class MyDialog extends Window {
    public interface SaveListener {
        public void save(SomeDataModel modifiedData);

    public MyDialog(SaveListener save) {

Then use it for example:

SomeDataModel data;

MyDialog dlg = new MyDialog(data, (modifiedData) -> {
    data = modifiedData;
    Notification.show("Data changed");
