Interface FieldChangeListener

All Known Implementing Classes:

Dialog

public interface FieldChangeListener

Listener interface for handling Field change events.

Classes that want to handle change events should implement this interface. Field classes identify the listener object to handle change events with their setChangeListener method.

Note: A listener may get notified by an unexpected field. For example, suppose one registers to listen to a ChoiceField. If the user puts the field into "change option" mode, this funtion will be called from that instance. Use Field.getOriginal() to find out what the original field is.
