Java에서 창을 닫는 방법:
1. JFrame의 enableEvents 및 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); } } }
2를 사용합니다. WindowListener 인터페이스를 직접 구현합니다.
//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) { } }
4. 폼 어댑터 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); } }
5. WindowListener 인터페이스
//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); } }
6를 간접적으로 구현합니다. 내부 클래스 사용
//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) { } }
J프레임 닫기 방법:
//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(); } }
프레임 닫기 방법은 다음과 같습니다.
setDefaultCloseOperation(EXIT_ON_CLOSE);
