All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.beans.PropertyChangeListener, java.io.Serializable, java.util.EventListener, Helpful, LayerManager.LayerChangeListener, MainLayerManager.ActiveLayerChangeListener, PreferenceChangedListener

public class MapView
extends NavigatableComponent
implements java.beans.PropertyChangeListener, PreferenceChangedListener, LayerManager.LayerChangeListener, MainLayerManager.ActiveLayerChangeListener

This is a component used in the MapFrame for browsing the map. It use is to provide the MapMode's enough capabilities to operate.

MapView holds meta-data about the data set currently displayed, as scale level, center point viewed, what scrolling mode or editing mode is selected or with what projection the map is viewed etc..

MapView is able to administrate several layers.
