Listener interface for handling changes in focus within fields.
Fields that want to handle focus change events should
implement this interface. Field classes identify the listener
object to handle focus change events with their
setFocusListener method.
Three kinds of focus events should be handled:
FOCUS_GAINED, FOCUS_LOST, and
FOCUS_CHANGED.
