JFrame.DISPOSE_ON_CLOSE只让当前的窗口关闭而已

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( );

}

java窗口关闭代码

给Frame 添加一个监听就可以了，如果你是用的JFrame不用添加监听直接点击小叉叉就可以关闭窗口了

Frame frame = new Frame("测试");

frame.setSize(300, 300);

frame.setVisible(true);

frame.addWindowListener(new WindowAdapter() {

public void windowClosing(WindowEvent e) {

System.exit(0);// 退出程序

}

});
