java窗体开发 java关闭窗体的六种方法

java关闭窗体的六种方法  

　　前段时间集中精力写了两篇论文 很久没写博文了 现在继续了

　　 使用JFrame的enableEvents和processWindowEvent

　　//Frame java

　　import java awt *;

　　import java awt event *;

　　import javax swing *;

　　public class Frame extends JFrame {

　　public Frame () {

　　enableEvents(AWTEvent WINDOW_EVENT_MASK);

　　this setSize(new Dimension( ));

　　this setTitle( Frame );

　　}

　　protected void processWindowEvent(WindowEvent e) {

　　super processWindowEvent(e);

　　if (e getID() == WindowEvent WINDOW_CLOSING) {

　　System exit( );

　　}

　　}

　　}

　　 直接实现WindowListener接口

　　//Frame java

　　import java awt *;

　　import java awt event *;

　　public class Frame extends Frame implements WindowListener {

　　public Frame () {

　　this setSize(new Dimension( ));

　　this setTitle( Frame );

　　this addWindowListener(this);

　　}

　　public void windowClosing(WindowEvent windowEvent) {

　　System exit( );

　　}

　　public void windowOpened(WindowEvent windowEvent) {  }

　　public void windowClosed(WindowEvent windowEvent) {  }

　　public void windowIconified(WindowEvent windowEvent) {  }

　　public void windowDeiconified(WindowEvent windowEvent) {  }

　　public void windowActivated(WindowEvent windowEvent) {  }

　　public void windowDeactivated(WindowEvent windowEvent) {  }

　　}

　　 直接继承窗体适配器WindowAdapter

　　//Frame java

　　import java awt *;

　　import java awt event *;

　　public class Frame extends  WindowAdapter {

　　public Frame () {

　　Frame f=new Frame();

　　f setSize(new Dimension( ));

　　f setTitle( Frame );

　　f addWindowListener(this);

　　f setVisible(true);

　　}

　　public static void main(String[] s){

　　new Frame ();

　　}

　　public void windowClosing(WindowEvent windowEvent) {

　　System exit( );

　　}

　　}

　　 间接继承窗体适配器WindowAdapter

　　//Frame java

　　import java awt *;

　　import java awt event *;

　　public class Frame extends  Frame {

　　public Frame () {

　　this setSize(new Dimension( ));

　　this setTitle( Frame );

　　this addWindowListener(new winAdapter());

　　this setVisible(true);

　　}

　　public static void main(String[] s){

　　new Frame ();

　　}

　　}

　　class winAdapter extends WindowAdapter{

　　public void windowClosing(WindowEvent windowEvent) {

　　System exit( );

　　}

　　}

　　 间接实现WindowListener接口

　　//Frame java

　　import java awt *;

　　import java awt event *;

　　public class Frame extends  Frame {

　　public Frame () {

　　this setSize(new Dimension( ));

　　this setTitle( Frame );

　　this addWindowListener(new winEventHandle());

　　this setVisible(true);

　　}

　　public static void main(String[] s){

　　new Frame ();

　　}

　　}

　　class winEventHandle implements WindowListener {

　　public void windowClosing(WindowEvent windowEvent) {

　　System exit( );

　　}

　　public void windowOpened(WindowEvent windowEvent) {  }

　　public void windowClosed(WindowEvent windowEvent) {  }

　　public void windowIconified(WindowEvent windowEvent) {  }

　　public void windowDeiconified(WindowEvent windowEvent) {  }

　　public void windowActivated(WindowEvent windowEvent) {  }

　　public void windowDeactivated(WindowEvent windowEvent) {  }

　　}

　　 使用Inner Class

　　//Frame java

　　import java awt *;

　　import java awt event *;

　　public class Frame {

　　public Frame (){

　　Frame f=new Frame();

　　f addWindowListener(new WindowAdapter(){

　　public void windowClosing(WindowEvent e){

　　System exit( );

　　}

　　});

　　f setSize(new Dimension( ));

　　f setVisible(true);

　　}

　　public static void main(String[] s){

　　new Frame ();

　　}

　　}

　　Jframe的关闭方法

　　setDefaultCloseOperation(EXIT_ON_CLOSE);

　　frame的关闭方法如下

　　this addWindowListener(new java awt event WindowAdapter() {

　　public void windowClosing(java awt event WindowEvent e) {

　　System exit( );

　　}
