 public abstract void mouseDragged(MouseEvent e); public abstract void mouseMoved(MouseEvent e); 

Java MouseMotionListener Example

 import java.awt.*; import java.awt.event.*; public class MouseMotionListenerExample extends Frame implements MouseMotionListener{ MouseMotionListenerExample(){ addMouseMotionListener(this);  setSize(300,300); setLayout(null); setVisible(true); } public void mouseDragged(MouseEvent e) { Graphics g=getGraphics(); g.setColor(Color.BLUE); g.fillOval(e.getX(),e.getY(),20,20); } public void mouseMoved(MouseEvent e) {}  public static void main(String[] args) { new MouseMotionListenerExample(); } }

Java MouseMotionListener Example 2

 import java.awt.*; import java.awt.event.MouseEvent; import java.awt.event.MouseMotionListener; public class Paint extends Frame implements MouseMotionListener{ Label l; Color c=Color.BLUE; Paint(){ l=new Label(); l.setBounds(20,40,100,20); add(l);  addMouseMotionListener(this);  setSize(400,400); setLayout(null); setVisible(true); } public void mouseDragged(MouseEvent e) { l.setText(“X=”+e.getX()+”, Y=”+e.getY()); Graphics g=getGraphics(); g.setColor(Color.RED); g.fillOval(e.getX(),e.getY(),20,20); } public void mouseMoved(MouseEvent e) { l.setText(“X=”+e.getX()+”, Y=”+e.getY()); } public static void main(String[] args) { new Paint(); } }
