SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
The listener interface for receiving "interesting" map events of a map.
The class that is interested in processing a map event implements this interface. The listener object created from that class is then registered with a GeographyMap using the GeographyMap's addMapListener method and removed by using removeMapListener method. A map event is generated when some property of the map is changed. For example: After a map is drawn, a map event is fired with the event type is MAP_DRAWN. A map event should has a correct type, and it may be one of the followings:
MapEvent.MAP_DRAWN
,
MapEvent.MAP_VIEWPORT_CHANGED
,
MapEvent.MAP_WINDOW_CHANGED
,
MapEvent.MAP_SCALE_CHANGED
,
MapEvent.MAP_SELECTEDFEATURE_CHANGED
,
MapEvent.MAP_QUERYLAYER_CHANGED
