Re: [OpenMap Users] BasicMapPanel

Hi Rachel,

The BasicMapPanel *is* the JPanel you are looking for. In your code,
you aren't adding the MapPanel to the EVMap, which would make your code
work, too.

To prevent the BasicMapPanel from searching for an openmap.properties
file, create it with a PropertyHandler created from an empty
Properties. See code below, modified from your code to use the
BasicMapPanel:

import java.awt.*;
import javax.swing.*;
import java.util.Properties;

import com.bbn.openmap.*;
import com.bbn.openmap.layer.*;
import com.bbn.openmap.layer.shape.*;
import com.bbn.openmap.gui.*;

public class map {

     /** Creates a new instance of TestFile */
     public static void main(String args[]) {

         //BackgroundMap map = new BackgroundMap();
         EVMap ev = new EVMap();

         JFrame frame = new JFrame("Experiential Systems Group Map
Interface");

         frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

         frame.getContentPane().add(ev);

         frame.setVisible(true);

     }

     public static class EVMap extends BasicMapPanel {

         public EVMap() {
                // Prevent the BasicMapPanel from creating a PropertyHandler with no
                // properties, which would cause it to look for an openmap.properties
file:

             super(new PropertyHandler(new Properties()));
             try {

                 // Get the default MapBean that the BasicMapPanel
created.
                 MapBean mapBean = getMapBean();

                 // Set the map's center
                 mapBean.setCenter(new LatLonPoint(43.0f, -95.0f));
                 // Set the map's scale 1:120 million
                 mapBean.setScale(120000000f);

                 addMapComponent(new LayerHandler());
                 addMapComponent(new GraticuleLayer());

                 ShapeLayer shapeLayer = new ShapeLayer();

                 Properties shapeLayerProps = new Properties();
                 shapeLayerProps.put("prettyName", "Political Solid");
                 shapeLayerProps.put("lineColor", "000000");
                 shapeLayerProps.put("fillColor", "BDDE83");
                 shapeLayerProps.put("shapeFile",
                                            
"C:/openmap-4.6/ESGData/world.shp");
                 shapeLayer.setProperties(shapeLayerProps);
                 shapeLayer.setVisible(true);

                 addMapComponent(shapeLayer);

                 // Create the directional and zoom control tool
                 addMapComponent(new OMToolSet());
                 // Create an OpenMap toolbar
                 addMapComponent(new ToolPanel());

             } catch (MultipleSoloMapComponentException msmce) {
                 System.out.println(msmce.getMessage());
             }
         }

     }
}
