java - 无法将 Control-Backspace 映射到 KeyStroke

我无法将 Control-Backspace 键映射到 KeyStroke。以下对我来说毫无意义。

import java.awt.event.KeyEvent;
import javax.swing.KeyStroke;
public class TestControlBackspace {
    public static void main(String[] args) {
        KeyStroke ks1 = KeyStroke.getKeyStroke(KeyEvent.VK_BACK_SPACE, KeyEvent.VK_CONTROL);
        KeyStroke ks2 = KeyStroke.getKeyStroke(KeyEvent.VK_BACK_SPACE, KeyEvent.VK_SHIFT);
        KeyStroke ks3 = KeyStroke.getKeyStroke(KeyEvent.VK_BACK_SPACE, 0);
        System.out.println(ks1);
        System.out.println(ks2);
        System.out.println(ks3);
    }
}

输出:

shift 按下 BACK_SPACE

按下 BACK_SPACE

按下 BACK_SPACE

我在这里错过了什么吗？

最佳答案

您可能忘记阅读 documentation 。请注意，修饰符掩码来自与按下的键不同的位置。

import java.awt.event.InputEvent;
import java.awt.event.KeyEvent;
import javax.swing.KeyStroke;
public class TestControlBackspace {
    public static void main(String[] args) {
        KeyStroke ks1 = KeyStroke.getKeyStroke(KeyEvent.VK_BACK_SPACE, InputEvent.SHIFT_DOWN_MASK);
        KeyStroke ks2 = KeyStroke.getKeyStroke(KeyEvent.VK_BACK_SPACE, InputEvent.CTRL_DOWN_MASK);
        KeyStroke ks3 = KeyStroke.getKeyStroke(KeyEvent.VK_BACK_SPACE, 0);
        System.out.println(ks1);
        System.out.println(ks2);
        System.out.println(ks3);
    }
}
