@Deprecated public class DelegatingClickListenerCollection
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); }
