Java Swing-在Mac上，侦听Quit事件 [英] Java Swing - On a Mac, listening for Quit event

问题描述

在Mac上的Java应用程序中，您可以单击顶部栏，然后选择退出以退出程序.如何将侦听器添加到我的JFrame中以进行侦听?

In a Java application on a Mac, you can click the top bar and select Quit to exit the program. How can I add a listener to my JFrame to listen to this?

我对此进行了搜索，找到了ApplicationListener，但是Eclipse在其中添加了一个划掉的"字样，似乎认为它已被弃用了.

I did a search on this and found ApplicationListener, however Eclipse puts a "cross out" in this and seems to think its deprecated or something.

具体地说，我发现使用com.apple.eawt.ApplicationListener，但是我该怎么做?我需要下载此com.apple.eawt软件包吗?我似乎找不到它.

Specifically, I found to use com.apple.eawt.ApplicationListener, but how do I do this? Do I need to download this com.apple.eawt package? I can't seem to find it.

推荐答案
