Java Swing -当框架B可见时，如何让框架A不被使用？

import javax.swing.*;

public class Main {
    public static void main(String[] args) {
        JFrame frameA = new JFrame("框架A");
        frameA.setSize(300, 200);
        frameA.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frameA.setVisible(true);

        JFrame frameB = new JFrame("框架B");
        frameB.setSize(300, 200);
        frameB.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frameB.setVisible(true);

        // 监听框架B的可见状态
        frameB.addWindowListener(new java.awt.event.WindowAdapter() {
            @Override
            public void windowOpened(java.awt.event.WindowEvent windowEvent) {
                // 当框架B可见时，将框架A设置为不可用
                frameA.setEnabled(false);
            }

            @Override
            public void windowClosed(java.awt.event.WindowEvent windowEvent) {
                // 当框架B不可见时，将框架A设置为可用
                frameA.setEnabled(true);
            }
        });
    }
}
