All Implemented Interfaces:
  javax.accessibility.Accessible, java.beans.beancontext.BeanContextChild, java.beans.beancontext.BeanContextMembershipListener, java.awt.event.ComponentListener, java.util.EventListener, java.awt.image.ImageObserver, LightMapHandlerChild, java.awt.MenuContainer, ProjectionListener, java.beans.PropertyChangeListener, PropertyConsumer, java.io.Serializable, Tool

public class OverviewMapHandler
extends OMToolComponent
implements ProjectionListener, java.io.Serializable, PropertyConsumer, java.beans.PropertyChangeListener, java.awt.event.ComponentListener

The OverviewMapHandler contains a MapBean that contains a projection that reflects another MapBean's projection. It manages the two MapBeans and the differences in the projections betwen them. The OverviewMapHandler can have a projection type independent of that of the source MapBean (the MapBean that the OverviewMapHandler's MapBean is paying attention to). It also contains a scale factor, which is a multiplier to use against the scale of the source MapBean's scale.

The OverviewMapHandler MapBean can also be used to control the source MapBean's projection center and scale. The source MapBean just needs to be added to the OverviewMapHandler by OverviewMapHandler.addControlledMap(MapBean).

The OverviewMapHandler needs to be added to the source MapBean as a ProjectionListener. Then, the overview MapBean can be added to the ContentPane of a Component by calling Component.setContentPane(OverviewMapHandler.getMap()); The OverviewMapHandler Should also be added as a ComponentListener to the Component.

After the first projectionChanged() call is received, the OverviewMapHandler knows about the source MapBean. Since the OverviewMapHandler is a ComponentListener and will therefore find out when it's parent is hidden, it will disengage and engage itself from the source MapBean as it's visibility changes.

To get the overview map to appear in the OpenMap application, add the following properties to your openmap.properties file:

       # First, add overviewMapHandler to the openmap.components marker name list.  Then, add:

       overviewMapHandler.class=com.bbn.opemap.gui.OverviewMapHandler
       overviewMapHandler.overviewLayers=overviewLayer
       overviewMapHandler.overviewScaleFactor=10f
       overviewMapHandler.overviewMinScale=100f
       # Set the Unit of Measure for the overviewMinScale property
       # Omission of  overviewMinScaleUom indicates that overviewMinScale
       # is an projection map scale instead of a distance.
       overviewMapHandler.overviewMinScaleUom=km

       # 'overviewStatusLayer' is a marker name for any attributes you may
       # want to pass to the overviewStatusLayer instance, in addition to
       # being used to define the class to use for that special layer.
       overviewMapHandler.overviewStatusLayer.class=com.bbn.openmap.layer.OverviewMapAreaLayer
       # Properties can be passed to the overview status layer by listing
       # them with the OverviewMapHandler prefix.

       # Set the line color for the coverage box outline...
       # overviewMapHandler.lineColor=FFFF0000

       # A sample overview map layer
       overviewLayer.class=com.bbn.openmap.layer.shape.ShapeLayer
       overviewLayer.prettyName=Overview
       overviewLayer.shapeFile=/home/dietrick/dev/openmap/share/dcwpo-browse.shp
       overviewLayer.spatialIndex=/home/dietrick/dev/openmap/share/dcwpo-browse.ssx
       overviewLayer.lineColor=ff000000
       overviewLayer.fillColor=ffbdde83

If layers are not added to the overview map, then it won't show up in the application.

  Sets the properties for the `Layer`. This allows `Layer` s to get a richer set of parameters than the `setArgs` method. Part of the PropertyConsumer interface. Layers which override this method should do something like: `

       public void setProperties(String prefix, Properties props) {
           super.setProperties(prefix, props);
           // do local stuff
       }

    `setProperties` in class `OMToolComponent`
  Parameters:
    `prefix` - the token to prefix the property names
    `props` - the `Properties` object

### getProperties

    public java.util.Properties getProperties(java.util.Properties props)

  Specified by:
    `getProperties` in interface `PropertyConsumer`
  Overrides:
    `getProperties` in class `OMToolComponent`
  Parameters:
    `props` - a Properties object to load the PropertyConsumer properties into. If props equals null, then a new Properties object should be created.
  Returns:
    Properties object containing PropertyConsumer property values. If getList was not null, this should equal getList. Otherwise, it should be the Properties object created by the PropertyConsumer.

### getPropertyInfo

    public java.util.Properties getPropertyInfo(java.util.Properties list)

  Method to fill in a Properties object with values reflecting the properties able to be set on this PropertyConsumer. The key for each property should be the raw property name (without a prefix) with a value that is a String that describes what the property key represents, along with any other information about the property that would be helpful (range, default value, etc.). For Layer, this method should at least return the 'prettyName' property.

  Specified by:
    `getPropertyInfo` in interface `PropertyConsumer`
  Overrides:
    `getPropertyInfo` in class `OMToolComponent`
  Parameters:
    `list` - a Properties object to load the PropertyConsumer properties into. If getList equals null, then a new Properties object should be created.

    public void deactivateMouseMode()

  Disconnects the mouse mode from the overview map.

### addControlledMap

    public void addControlledMap(MapBean l)

  Add a controlled MapBean to the OverviewMapHandler. Use this method to add another MapBean to the overview map in order to have its projection controlled by the overview panel. If the overview panel is clicked on, the listening MapBean will be recentered. If a box is drawn with a mouse drag, the scale of the controlled map will be modified.

  Parameters:
    `l` - MapBean.

### removeControlledMap

    public void removeControlledMap(MapBean l)

  Remove a controlled MapBean from the OverviewMapHandler.

  Parameters:
    `l` - a MapBean.

### getMap

    public MapBean getMap()

  Get the overview MapBean.

  Returns:
    overview MapBean.

### setMap

    public void setMap(MapBean map)

  Set the overview MapBean.

### getControlledMapListeners

    public OverviewMapHandler.ControlledMapSupport getControlledMapListeners()

  Get the ControlledMapSupport, which usually contains the source map.

### setControlledMapListeners

    public void setControlledMapListeners(OverviewMapHandler.ControlledMapSupport list)

  Set the ControlledMapSupport, which usually contains the source map.

### getStatusLayer

    public Layer getStatusLayer()

  Get the status layer, which is always drawn on top of the other layers, and maintained separately from other layers.

### setStatusLayer

    public void setStatusLayer(Layer layer)

  Get the status layer, which is always drawn on top of the other layers, and maintained separately from other layers. If the layer is also an OverviewMapStatusListener, it will receive source map projection changes, so it can draw stuff on itself representing what's going on the source map.

### setScaleFactor

    public void setScaleFactor(float setting)

  Set the scale factor to use between the source MapBean and the overview MapBean. It's a direct multiplier, so the overview MapBean can actually be a magnified map, too. The overview map scale = source MapBean scale * scaleFactor.

  Parameters:
    `setting` - scale factor

### getScaleFactor

    public float getScaleFactor()

  Get the scale factor used for the overview MapBean.

### setProjection

    public void setProjection(Proj proj)

  Set the projection of the overview MapBean. Lets you set the type, really. The scale and center will be reset when a projection event is received.

### getProjection

    public Proj getProjection()

  Get the current projection of the overview MapBean.

### setMinScale

    public void setMinScale(float setting)

  Set the minimum scale to use for the overview map. If this is set too small with a very general map layer, it won't be of any use, really, if it gets really zoomed in.

  Parameters:
    `setting` - the scale setting - 1:setting

### setMinScale

    public void setMinScale(float width,
                            Length uom)

  Set the minimum scale to use for the overview map. If this is set too small with a very general map layer, it won't be of any use, really, if it gets really zoomed in.

### getMinScale

    public float getMinScale()

### componentShown

    public void componentShown(java.awt.event.ComponentEvent e)

  Invoked when component has been shown. This component should be the component that contains the OverviewMapHandler.

  Specified by:
    `componentShown` in interface `java.awt.event.ComponentListener`

### componentHidden

    public void componentHidden(java.awt.event.ComponentEvent e)

  Invoked when component has been hidden. This component should be the component that contains the OverviewMapHandler.

  Specified by:
    `componentHidden` in interface `java.awt.event.ComponentListener`

### componentResized

    public void componentResized(java.awt.event.ComponentEvent e)

  Specified by:
    `componentResized` in interface `java.awt.event.ComponentListener`

### componentMoved

    public void componentMoved(java.awt.event.ComponentEvent e)

  Specified by:
    `componentMoved` in interface `java.awt.event.ComponentListener`

### getOverviewFrameActionListener

    public java.awt.event.ActionListener getOverviewFrameActionListener()

  Return an ActionListener that will bring up an independent window with an Overview Map.

  Returns:
    ActionListener that brings up a Window when an actionPerformed is called.

### getFace

    public java.awt.Container getFace()

  Tool interface method.

  Specified by:
    `getFace` in interface `Tool`
  Overrides:
    `getFace` in class `OMToolComponent`
  Returns:
    The container GUI for this tool, may be null.

### findAndInit

    public void findAndInit(java.lang.Object someObj)

  Called when the OverviewMapHandler is added to the BeanContext, and whenever an object is added to the BeanContext after that. The OverviewMapHandler looks for a MapBean to use as a source map, and for a PropertiesHandler object to use to load itself with layers and other properties. If a source MapBean is already set and another MapBean is found, the last MapBean will be used as the source MapBean. Every time a PropertyHandler is found, the OverviewMapHandler will reinitialize itself.

  Specified by:
    `findAndInit` in interface `LightMapHandlerChild`
  Overrides:
    `findAndInit` in class `OMComponentPanel`
  Parameters:
    `someObj` - the object being added to the BeanContext

### findAndUndo

    public void findAndUndo(java.lang.Object someObj)

  Specified by:
    `findAndUndo` in interface `LightMapHandlerChild`
  Overrides:
    `findAndUndo` in class `OMComponentPanel`

### propertyChange

    public void propertyChange(java.beans.PropertyChangeEvent pce)

  PropertyChangeListener method, to listen for the source map's background changes. Act on if necessary.

  Specified by:
    `propertyChange` in interface `java.beans.PropertyChangeListener`
