All Implemented Interfaces:

com.bbn.openmap.event.MapMouseListener, com.bbn.openmap.event.ProjectionListener, com.bbn.openmap.ProjectionPainter, com.bbn.openmap.PropertyConsumer, java.awt.event.ActionListener, java.awt.event.ComponentListener, java.awt.event.KeyListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.beans.beancontext.BeanContextChild, java.beans.beancontext.BeanContextMembershipListener, java.io.Serializable, java.util.EventListener, MouseWheelCanZoomMap

public class DrawLayer
extends com.bbn.openmap.Layer
implements com.bbn.openmap.event.MapMouseListener, java.awt.event.KeyListener, java.awt.event.ComponentListener, MouseWheelCanZoomMap

This class implements an overlay on the OpenMap map panel that permits the user to draw arbitrary geometrical lines and objects, suitable for marking and highlighting areas of interest on the map. Note that these overlays are completely independent of the information drawn from the OpenStreetMap data sets and from received APRS stations and objects.
