Class PanListener

java.lang.Object
  org.deegree_impl.enterprise.control.AbstractListener
      org.deegree_impl.clients.wmsclient2.control.AbstractMapListener
          org.deegree_impl.clients.wmsclient2.control.PanListener

All Implemented Interfaces:

java.util.EventListener, WebListener

public class PanListener

extends AbstractMapListener

will be called if the client forces a pan action and performs it. A extending class can change the behavior of the response by overriding the modifyModel() and the modifySettings() methods.

pan

private double[] pan(double minx,
                     double miny,
                     double maxx,
                     double maxy,
                     double delta,
                     java.util.HashMap model)
