## com.bbn.openmap.event
Class AbstractMouseMode

    java.lang.Object
      com.bbn.openmap.MapHandlerChild
          com.bbn.openmap.OMComponent
              com.bbn.openmap.event.AbstractMouseMode

All Implemented Interfaces:
  java.beans.beancontext.BeanContextChild, java.beans.beancontext.BeanContextMembershipListener, java.util.EventListener, LightMapHandlerChild, MapMouseMode, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.event.MouseWheelListener, PaintListener, PropertyConsumer, java.io.Serializable

Direct Known Subclasses:
  CoordMouseMode, NullMouseMode

public class AbstractMouseMode
extends OMComponent
implements MapMouseMode, java.io.Serializable

Base class of the MouseModes. It takes care of the administrative aspects of being a mouse mode, but does not respond to MouseEvents.

The ID and pretty name can be set in the properties file.

        # Name that layers use to get events from this mode
        mousemode.id=ID
        # Tooltip and Menu name for mode
        mousemode.prettyName=Display Name

This class delegates much of the work of managing its listeners to a MapMouseSupport object.
