ucar.unidata.view.geoloc
Class ProjectionManager

java.lang.Object
  ucar.unidata.view.geoloc.ProjectionManager

All Implemented Interfaces:

ActionListener, EventListener

public class ProjectionManager
extends Object
implements ActionListener

Manages a modal dialogue box that allows the user to define projections using subclasses of ucar.unidata.gis.ProjectionImpl.

    1) It uses bean introspection on ProjectionImpl subclasses to dynamically
       configure edit fields for the projection's parameters. The subclass should
       define getXXX() and setXXX() methods for each parameter.
    3) when the user selects a projection, a NewProjectionEvent is sent to any listeners
    4) currently the list of possible projection classes is maintained as a
       hard-wired list of class names. This should be rethunk.
