Examples of com.bbn.openmap.event.MapMouseListener

com.bbn.openmap.event.MapMouseListener
The MapMouseListener interface is for use by a layer interested in getting mouse events when the mouse cursor is over the MapBean. These events will be coming from an event delegate object, that distributes events based on the current "mouse mode" of the map.
NOTE: It is very important that if a MapMouseListener is being implemented for a Layer object, the Layer.getMapMouseListener() method be modified for the layer to return the MapMouseListener. The layer returns null by default, and this will result in the MapMouseListener NEVER receiving events. @see SelectMouseMode @see NavMouseMode
