java中關(guān)閉當(dāng)前窗口用什么代碼

setDefaultCloseOperation(JFrame.EXIT_ON_CLOES)會(huì)讓整個(gè)程序都退出

JFrame.DISPOSE_ON_CLOSE只讓當(dāng)前的窗口關(guān)閉而已

java關(guān)閉窗體的六種方法

前段時(shí)間集中精力寫(xiě)了兩篇論文 很久沒(méi)寫(xiě)博文了 現(xiàn)在繼續(xù)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( );

}

}

}

直接實(shí)現(xiàn)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) {? }

}

直接繼承窗體適配器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( );

}

}

間接繼承窗體適配器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( );

}

}

間接實(shí)現(xiàn)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的關(guān)閉方法

setDefaultCloseOperation(EXIT_ON_CLOSE);

frame的關(guān)閉方法如下

this addWindowListener(new java awt event WindowAdapter() {

public void windowClosing(java awt event WindowEvent e) {

System exit( );

}

java窗口關(guān)閉代碼

給Frame 添加一個(gè)監(jiān)聽(tīng)就可以了，如果你是用的JFrame不用添加監(jiān)聽(tīng)直接點(diǎn)擊小叉叉就可以關(guān)閉窗口了

Frame?frame?=?new?Frame("測(cè)試");

frame.setSize(300,?300);

frame.setVisible(true);

frame.addWindowListener(new?WindowAdapter()?{

public?void?windowClosing(WindowEvent?e)?{

System.exit(0);//?退出程序

}

});
