How to disable (or hide) the close (x) button on a JFrame?
I want the frame to have a deactivated close button, but I don't want to do frame.setDefaultCloseOperation( JFrame.DO_NOTHING_ON_CLOSE );
nor frame.setUndecorated(true).
我希望框架有一个停用的关闭按钮，但我不想这样做frame.setDefaultCloseOperation( JFrame.DO_NOTHING_ON_CLOSE )；也不frame.setUndecorated(true)。
I want the frame to appear but the close button should look inactive/disabled.
我希望框架出现，但关闭按钮应该看起来不活动/禁用。
If we cant achieve this in JFrameis there a way to do this? You suggestions will be of great help.
如果我们不能做到这一点，JFrame有没有办法做到这一点？你的建议会有很大帮助。

I think the best answer is that it is not possible.
我认为最好的答案是不可能。
I would choose the DO_NOTHING_ON_CLOSEand override the windowClosing event in its WindowAdapter as the best option.
我会选择DO_NOTHING_ON_CLOSE并覆盖其 WindowAdapter 中的 windowClosing 事件作为最佳选择。
frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
// do whatever else
}
});
