什么会影响Mac JFrame上缩放按钮的启用状态?

下面是一个简单的示例,展示了macosx上的预期行为;您可以将其与您正在做的操作进行比较,以供参考。

import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import javax.swing.AbstractAction;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JToggleButton;

public class FrameTest extends JPanel implements Runnable {

    private JFrame f;
    private boolean test;

    public static void main(String[] args) {
        EventQueue.invokeLater(new FrameTest());
    }

    @Override
    public void run() {
        f = new JFrame("Test");
        test = f.isResizable();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.add(this);
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    }

    public FrameTest() {
        this.add(new JToggleButton(new AbstractAction("Test") {

            @Override
            public void actionPerformed(ActionEvent e) {
                test = !test;
                f.setResizable(test);
            }
        }));
    }
}
