com.luciad.format.kml22.view.gxy.TLcdKML22GXYViewParametersUpdater

public class TLcdKML22GXYViewParametersUpdater
extends Object

This class is used to update all parameters of a TLcdKML22Parameters which are derived from a 2D view.

A property change listener can be attached to the view to update the KML parameters whenever a a relevant view property has been changed, as follows:

   ILcdGXYView view = ...
   TLcdKMl22GXYViewParametersUpdater updater = ..

   view.addPropertyChangeListener( new PropertyChangeListener() {
     public void propertyChange( PropertyChangeEvent evt ) {
       // The KML parameters are computed from the worldOrigin and scale.
       if ( "worldOrigin".equals( evt.getPropertyName() ) || "scale".equals( evt.getPropertyName() ) ) {
         updater.updateParameters(view);
       }
     }
   } );
