How to disable (or hide) the close (x) button on a JFrame?
提问by florin
I have a window (derived from JFrame) and I want to disable the close button during certain operations which are not interruptible. I know I can make the button not do anything (or call a handler in a WindowListener) by calling
我有一个窗口（派生自 JFrame），我想在某些不可中断的操作中禁用关闭按钮。我知道我可以通过调用使按钮不执行任何操作（或调用 WindowListener 中的处理程序）
setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
but I would like to make it clear visually that it is pointless to click it.
但我想在视觉上清楚地表明点击它是没有意义的。

This is probably the best you are going to get:
这可能是您将得到的最好的结果：
setUndecorated(true);
getRootPane().setWindowDecorationStyle(JRootPane.NONE);
This will remove the entire titlebar, java doesn't really specify a way to remove individual components of the titlebar
这将删除整个标题栏，java 并没有真正指定删除标题栏各个组件的方法
