In the future, Swing related questions should be
posted in the Swing forum.
Maybe you just use a JPanel as a rectangle by setting
the border of the panel. Then you can add a
MouseListener to the panel.The code is as follows
import javax.swing.*;
   import java.awt.*;
   import java.awt.geom.*;
   import java.awt.image.*;
   import java.awt.event.MouseEvent;
     import javax.swing.event.MouseInputAdapter;
    class MapImager extends JPanel
           BufferedImage imageMap;
          private static JFrame frame = new JFrame();
           //private String botswana = "Images/botswana.jpg";
           private Rectangle2D.Double square =
           new Rectangle2D.Double(0, 0, 350, 350);
           private GradientPaint gradient =
           new GradientPaint(0, 0, Color.red, 175, 175, Color.yellow,true); // true means to repeat pattern
           private final static int SQUARE_EDGE_LENGTH = 10;
            private static JPanel panel;
            private static int xPos;
            private static int yPos;
            private static int xP;
          private static int yP;
          private MapPanel mapPanel;
           public MapImager (){
              //imageMap = getBufferedImage(botswana, this);
               xPos = 186;yPos = 100;
          static MouseInputAdapter mia = new MouseInputAdapter(){
               public void mousePressed(MouseEvent e){
                    xPos = e.getX();
                   System.out.println(" The X2 When mousePressed Cordinates are "+xPos);
                   yPos = e.getY();
                   System.out.println(" The Y2 When mousePressed Cordinates are "+yPos);
                   frame.repaint();
               public void mouseDragged(MouseEvent e){
                    xPos = e.getX();
                   System.out.println(" The X2 When mouseDragged Cordinates are "+xPos);
                   yPos = e.getY();
                   System.out.println(" The Y2 When mouseDragged Cordinates are "+yPos);
                   frame.repaint();
           public void paintComponent (Graphics g){
             Graphics2D g2d = (Graphics2D)g;
             this.setBackground(Color.WHITE);
               g2d.setPaint(gradient);
               g2d.fill(square);
                 g2d.drawImage (imageMap, 0, 0, this);
               g.setColor(Color.RED);//I want to draw as many as i want and have each move freely on the frame.
               g.fillRect(xPos-(SQUARE_EDGE_LENGTH/2), yPos-(SQUARE_EDGE_LENGTH/2), SQUARE_EDGE_LENGTH, SQUARE_EDGE_LENGTH);
     public static BufferedImage getBufferedImage(String imageFile,Component c){
         Image image = c.getToolkit().getImage(imageFile);
         waitForImage(image, c);
         BufferedImage bufferedImage =
            new BufferedImage(image.getWidth(c), image.getHeight(c),
                        BufferedImage.TYPE_INT_RGB);
         Graphics2D g2d = bufferedImage.createGraphics();
         g2d.drawImage(image, 0, 0, c);
         return(bufferedImage);
     public static boolean waitForImage(Image image, Component c){
         MediaTracker tracker = new MediaTracker(c);
         tracker.addImage(image, 0);
         try {
            tracker.waitForAll();
             catch(InterruptedException ie) {}
         return(!tracker.isErrorAny());
       public static void main(String[] args){
              MapImage map = new MapImage();
              frame.add(map);
               frame.addMouseListener(mia);
               frame.addMouseMotionListener(mia);
             frame.setSize(360, 380);
              frame.setTitle("Map of Botswana");
              frame.setVisible(true);
              frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
