Package org.apache.log4j.chainsaw.prefs

## Interface SettingsListener

- All Superinterfaces:
    `EventListener`
  All Known Subinterfaces:
    `Profileable`
  All Known Implementing Classes:
    `ApplicationPreferenceModelSaver`, `LogPanel`, `LogUI`, `MRUFileListPreferenceSaver`, `ReceiversPanel`

      public interface SettingsListener
      extends EventListener

  Components, or objects, that are interested in being notified when Settings are loaded or being saved, can implement this interface.

  'Settings' are Chainsaw wide preferences, and are not specific to a particular tab identifer etc. See the correspoing ProfileListener and related classes for a discussion on profile specific events etc.

  The implementing class can use this event notification opportunity to load setting information stored previously, or to request that setting information be stored.

  NOTE: This contract does _*NOT*_ dictate that the Thread invoking these methods will be the Swing's Event dispatching event, it could be any arbitary thread. Having said that, it COULD be the Swing's Event dispatching event, but this contract makes no guarantee.
