There is no need for such a tutorial since GWT source is available.
You just have to study existing widget's code.
Concerning the event mechanism, the following example shows how to
deal with click events :
public class MyWidget extends Widget implements SourecesClickEvents {
private ClickListenerCollection clickListeners;
public void addClickListener(ClickListener listener) {
if (clickListeners == null) {
clickListeners = new ClickListenerCollection();
sinkEvents(Event.ONCLICK);
}
clickListeners.add(listener);
}
public void removeClickListener(ClickListener listener) {
if (clickListeners != null) {
clickListeners.remove(listener);
}
}
}
