    Question Movable message with JTextfield

    Hi everybody, i have a problem on this code.
    The ideas is to make a moveable message and that string message obtained from JTextField

    _______________________________________________
    |JPanel("Input Word") | JTextField |
    |______________________________________________|
    | |
    | |
    | |
    | here is the moveable message |
    | |
    | |
    |______________________________________________|

    This is the part of my code, not finished yet.

    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;
     
     
    public class TestListener extends JFrame {
     
    	private JTextField jtfMessage = new JTextField();
    	private JPanel p = new JPanel(new GridLayout(1, 2));
     
    	public TestListener() {
    		p.add(new JLabel("Word"));
    		p.add(jtfMessage);
    		//add(p, BorderLayout.CENTER);
    		add(new MovableMessagePanel("Welcome to Java"));
    	}
     
    	public static void main(String[] args) {
    		TestListener frame = new TestListener();
    		frame.setSize(300, 300);
    		frame.setTitle("Test move and Listener");
    		frame.setLocationRelativeTo(null);
    		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    		frame.setVisible(true);
    	}
     
    	private class MovableMessagePanel extends JPanel {
    		private String message = "Welcome to java";
    		int x = 20;
    		int y = 20;
     
    		public MovableMessagePanel(String s) {
    			message = s;
    			addMouseMotionListener(new MouseMotionAdapter() {
    				public void mouseDragged(MouseEvent e) {
    					x = e.getX();
    					y = e.getY();
    					repaint();
    				}
    			});
    		}
     
    		protected void paintComponent(Graphics g) {
    			super.paintComponent(g);
    			g.drawString(message, x, y);
    		}
    	}
    }

    If i use BorderLayout.CENTER for jtextfield
    and BorderLayout.SOUTH for movablemessage

    will cause the moveablemessage disappear.
    Please help me thanks.
