本篇文章給大家分享的是有關(guān)java中關(guān)閉窗口的方法,小編覺得挺實(shí)用的,因此分享給大家學(xué)習(xí),希望大家閱讀完這篇文章后可以有所收獲,話不多說,跟著小編一起來看看吧。
java關(guān)閉窗口的方法:
1、使用JFrame的enableEvents和processWindowEvent
//Frame1.java import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Frame1 extends JFrame { public Frame1() { enableEvents(AWTEvent.WINDOW_EVENT_MASK); this.setSize(new Dimension(400, 300)); this.setTitle("Frame1"); } protected void processWindowEvent(WindowEvent e) { super.processWindowEvent(e); if (e.getID() == WindowEvent.WINDOW_CLOSING) { System.exit(0); } } }
2.直接實(shí)現(xiàn)WindowListener接口
//Frame1.java import java.awt.*; import java.awt.event.*; public class Frame1 extends Frame implements WindowListener { public Frame1() { this.setSize(new Dimension(400, 300)); this.setTitle("Frame1"); this.addWindowListener(this); } public void windowClosing(WindowEvent windowEvent) { System.exit(0); } 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) { } }
3.直接繼承窗體適配器WindowAdapter
//Frame1.java import java.awt.*; import java.awt.event.*; public class Frame1 extends WindowAdapter { public Frame1() { Frame f=new Frame(); f.setSize(new Dimension(400, 300)); f.setTitle("Frame1"); f.addWindowListener(this); f.setVisible(true); } public static void main(String[] s){ new Frame1(); } public void windowClosing(WindowEvent windowEvent) { System.exit(0); } }
4.間接繼承窗體適配器WindowAdapter
//Frame1.java import java.awt.*; import java.awt.event.*; public class Frame1 extends Frame { public Frame1() { this.setSize(new Dimension(400, 300)); this.setTitle("Frame1"); this.addWindowListener(new winAdapter()); this.setVisible(true); } public static void main(String[] s){ new Frame1(); } } class winAdapter extends WindowAdapter{ public void windowClosing(WindowEvent windowEvent) { System.exit(0); } }
5.間接實(shí)現(xiàn)WindowListener接口
//Frame1.java import java.awt.*; import java.awt.event.*; public class Frame1 extends Frame { public Frame1() { this.setSize(new Dimension(400, 300)); this.setTitle("Frame1"); this.addWindowListener(new winEventHandle()); this.setVisible(true); } public static void main(String[] s){ new Frame1(); } } class winEventHandle implements WindowListener { public void windowClosing(WindowEvent windowEvent) { System.exit(0); } 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) { } }
6.使用Inner Class
//Frame1.java import java.awt.*; import java.awt.event.*; public class Frame1{ public Frame1(){ Frame f=new Frame(); f.addWindowListener(new WindowAdapter(){ public void windowClosing(WindowEvent e){ System.exit(0); } }); f.setSize(new Dimension(400, 300)); f.setVisible(true); } public static void main(String[] s){ new Frame1(); } }
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(0); } });
