Java关闭窗体方法总结.doc

Java关闭窗体方法总结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) cessWindowEvent(e); if (e.getID() = WindowEvent.WINDOW_CLOSING) System.exit(0); 2.直接实现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.直接继承窗体适配器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.间接继承窗体适配器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.间接实现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的关闭方法：setDefaultCloseOperation(EXIT_
