    @Deprecated
    public class DelegatingClickListenerCollection

extends ClickListenerCollection
implements ClickListener

`ClickListenerCollection` used to correctly hook up listeners which need to listen to events from another source.

For example, `Composite` widgets often need to listen to events generated on their wrapped widget. Upon the firing of a wrapped widget's event, the composite widget must fire its own listeners with itself as the source of the event. To use a `DelegatingClickListenerCollection`, simply use the `DelegatingClickListenerCollection` instead of a `ClickListenerCollection`. For example, in `SuggestBox`, the following code is used to listen to click events on the `SuggestBox`'s underlying widget.

      public void addClickListener(ClickListener listener) {
        if (clickListeners == null) {
          clickListeners = new DelegatingClickListenerCollection(this, box);
        }
        clickListeners.add(listener);
      }
