问题描述

我使用以下代码在java swing应用程序中显示地图

i used this following code for to show the map in java swing application

public class Tracking extends JInternalFrame  {
	
	private MapPanel map;
	private JLabel map1;
	
	public Tracking(String lan,String lat,String codeno){
		super("Tracking :"+codeno+"-Location",false,true,false,true);
		setDefaultCloseOperation(JInternalFrame.DISPOSE_ON_CLOSE);
		setSize(700,500);
		map=new MapPanel();
		map.setZoom(13);
		double lon = Double.valueOf(lan);
		double latt = Double.valueOf(lat);
		map1=new JLabel(new ImageIcon(ClassLoader.getSystemResource("Image/position.png")));
		Point position = map.computePosition(new Point2D.Double(lon,latt));
		map1.setLocation(position);
		map1.setFocusable(true);
		map.setIgnoreRepaint(true);
		map.setFocusable(true);
		map.setCenterPosition(position); // sets to the computed position
		add(map);
		map.add(map1);
	}
}
