如何禁用（或隐藏）JFrame上的关闭（x）按钮？ [英] How to disable (or hide) the close (x) button on a JFrame?

问题描述

我有一个窗口（从JFrame派生），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

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

setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);

但我想直观地说明点击它是没有意义的。

but I would like to make it clear visually that it is pointless to click it.

推荐答案

如果我理解正确的话，此错误报告表明目前无法做到这一点。

If I understand it correctly, this bug report indicates that this is currently not possible.
