DelegatingFocusListenerCollection

This class is deprecated.
Use delegateEvent(Widget, GwtEvent) instead

Class Overview

FocusListenerCollection 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 DelegatingFocusListenerCollection, simply use the DelegatingFocusListenerCollection instead of a FocusListenerCollection. For example, in SuggestBox, the following code is used to listen to focus events on the SuggestBox's underlying widget.

  public void addFocusListener(FocusListener listener) {
    if (focusListeners == null) {
      focusListeners = new DelegatingFocusListenerCollection(this, box);
    }
    focusListeners.add(listener);
  }
