在Java中处理键盘键ALT + F4组合 [英] Handle Keyboard Keys ALT+F4 combination in Java

问题描述

我是一名Windows用户，当我按
ALT + F4 时，我不想关闭我的jframe，

I am a windows user and i don't want to close my jframe when I press ALT+F4,

public void keyPressed(KeyEvent e) {
 if (KeyEvent.VK_SPACE, java.awt.event.InputEvent.CTRL_DOWN_MASK){
 }
}

获取击键并处理/停止关闭或切换jframe

get the keystrokes and handle/stop closing or switching of the jframe

所以如何在java中处理这个keypressed组合，
请帮助....

so how can i handle this keypressed combination in java, please help....

推荐答案

<如果确实你按下了组合键意味着即使关闭X也不起作用，前一个将锁定关闭。因此以下
审查：基于快速蜗牛回答更好：

the previous will lock closing if indeed you press the key combination meaning there on even close X will not work. hence the following REVIEW: much better based on fast snail answer:

public class OnKeyAltF4DontClose2 extends JFrame {//implements  WindowListener {

public OnKeyAltF4DontClose2() {
    setVisible(true);
    setDefaultCloseOperation(3);
    setBounds(400,400,400,400);



    addKeyListener(new KeyAdapter(){
        public void keyPressed(KeyEvent e) {

            if(((KeyStroke.getKeyStroke(KeyEvent.VK_SPACE, java.awt.event.InputEvent.ALT_DOWN_MASK)) != null)  &&  e.getKeyCode() == KeyEvent.VK_F4){

            e.consume();
            }

            }

    });

}
public static void main(String[] args) {
    new OnKeyAltF4DontClose2();

}

}
