1.使用JFrame的enableEvents和processWindowEvent<br /> //Frame1.java<br /> import java.awt.*;<br /> import java.awt.event.*;<br /> import javax.swing.*;<br /> public class Frame1 extends JFrame {<br /> public Frame1() {<br /> enableEvents(AWTEvent.WINDOW_EVENT_MASK);<br /> this.setSize(new Dimension(400, 300));<br /> this.setTitle(“Frame1”);<br /> }<br /> protected void processWindowEvent(WindowEvent e) {<br /> super.processWindowEvent(e);<br /> if (e.getID() == WindowEvent.WINDOW_CLOSING) {<br /> System.exit(0);<br /> }<br /> }<br /> }<br /> 2.直接实现WindowListener接口<br /> //Frame1.java<br /> import java.awt.*;<br /> import java.awt.event.*;<br /> public class Frame1 extends Frame implements WindowListener {<br /> public Frame1() {<br /> this.setSize(new Dimension(400, 300));<br /> this.setTitle(“Frame1”);<br /> this.addWindowListener(this);<br /> }<br /> public void windowClosing(WindowEvent windowEvent) {<br /> System.exit(0);<br /> }<br /> public void windowOpened(WindowEvent windowEvent) { }<br /> public void windowClosed(WindowEvent windowEvent) { }<br /> public void windowIconified(WindowEvent windowEvent) { }<br /> public void windowDeiconified(WindowEvent windowEvent) { }<br /> public void windowActivated(WindowEvent windowEvent) { }<br /> public void windowDeactivated(WindowEvent windowEvent) { }<br /> }<br /> 3.直接继承窗体适配器WindowAdapter<br /> //Frame1.java<br /> import java.awt.*;<br /> import java.awt.event.*;<br /> public class Frame1 extends WindowAdapter {<br /> public Frame1() {<br /> Frame f=new Frame();<br /> f.setSize(new Dimension(400, 300));<br /> f.setTitle(“Frame1”);<br /> f.addWindowListener(this);<br /> f.setVisible(true);<br /> }<br /> public static void main(String[] s){<br /> new Frame1();<br /> }<br /> public void windowClosing(WindowEvent windowEvent) {<br /> System.exit(0);<br /> }<br /> }<br /> 4.间接继承窗体适配器WindowAdapter<br /> //Frame1.java<br /> import java.awt.*;<br /> import java.awt.event.*;<br /> public class Frame1 extends Frame {<br /> public Frame1() {<br /> this.setSize(new Dimension(400, 300));<br /> this.setTitle(“Frame1”);<br /> this.addWindowListener(new winAdapter());<br /> this.setVisible(true);<br /> }<br /> public static void main(String[] s){<br /> new Frame1();<br /> }<br /> }<br /> class winAdapter extends WindowAdapter{<br /> public void windowClosing(WindowEvent windowEvent) {<br /> System.exit(0);<br /> }<br /> }<br /> 5.间接实现WindowListener接口<br /> //Frame1.java<br /> import java.awt.*;<br /> import java.awt.event.*;<br /> public class Frame1 extends Frame {<br /> public Frame1() {<br /> this.setSize(new Dimension(400, 300));<br /> this.setTitle(“Frame1”);<br /> this.addWindowListener(new winEventHandle());<br /> this.setVisible(true);<br /> }<br /> public static void main(String[] s){<br /> new Frame1();<br /> }<br /> }<br /> class winEventHandle implements WindowListener {<br /> public void windowClosing(WindowEvent windowEvent) {<br /> System.exit(0);<br /> }<br /> public void windowOpened(WindowEvent windowEvent) { }<br /> public void windowClosed(WindowEvent windowEvent) { }<br /> public void windowIconified(WindowEvent windowEvent) { }<br /> public void windowDeiconified(WindowEvent windowEvent) { }<br /> public void windowActivated(WindowEvent windowEvent) { }<br /> public void windowDeactivated(WindowEvent windowEvent) { }<br /> }<br /> 6.使用Inner Class<br /> //Frame1.java<br /> import java.awt.*;<br /> import java.awt.event.*;<br /> public class Frame1{<br /> public Frame1(){<br /> Frame f=new Frame();<br /> f.addWindowListener(new WindowAdapter(){<br /> public void windowClosing(WindowEvent e){<br /> System.exit(0);<br /> }<br /> });<br /> f.setSize(new Dimension(400, 300));<br /> f.setVisible(true);<br /> }<br /> public static void main(String[] s){<br /> new Frame1();<br /> }<br /> } </p> <p>Jframe的关闭方法： </p> <p>setDefaultCloseOperation(EXIT_ON_CLOSE); </p> <p>frame的关闭方法如下：<br /> this.addWindowListener(new java.awt.event.WindowAdapter() {<br /> public void windowClosing(java.awt.event.WindowEvent e) {<br /> System.exit(0);<br /> }<br /> });<br />
