Java Jwindow Class Example

JWINDOW

Java Swing Tutorial Explaining the JWindow Component. JWindow is Swing’s version of Window and is descended directly from that class. Like Window, it uses BorderLayout by default. Almost all Swing components are lightweight except JApplet, JFrame, JDialog, and JWindow.

JWINDOW SOURCE CODE

public class JWindowDemo extends JWindow {

 private int X = 0;
 private int Y = 0;
 public JWindowDemo() {
  setBounds(60, 60, 100, 100);
  addWindowListener(new WindowAdapter() {

   public void windowClosing(WindowEvent e) {
    System.exit(0); // An Exit Listener
   }
  });
  // Print (X,Y) coordinates on Mouse Click
  addMouseListener(new MouseAdapter() {

   public void mousePressed(MouseEvent e) {
    X = e.getX();
    Y = e.getY();
    System.out.println("The (X,Y) coordinate of window is ("
      + X + "," + Y + ")");
   }
  });
  addMouseMotionListener(new MouseMotionAdapter() {

   public void mouseDragged(MouseEvent e) {
    setLocation(getLocation().x + (e.getX() - X),
      getLocation().y + (e.getY() - Y));
   }
  });
  setVisible(true);
 }
 public static void main(String[] args) {
  new JWindowDemo();
 }
}
