在JFrame上运行功能关闭 [英] Run function on JFrame close

问题描述

void terminate() {}
protected JFrame frame = new JFrame();

当我按下关闭按钮时，如何获得 frame 来运行终止功能?

How can I get frame to run the terminate function when I press the close button?

我试图运行它，但是由于某种原因它无法打印测试(但是程序关闭了).有谁知道可能是什么问题?

I tried to run this, but for some reason it doesn't print test (however, the program closes). Does anyone have an idea what could be the problem?

frame.addWindowListener(new WindowAdapter() {
    public void WindowClosing(WindowEvent e) {
        System.out.println("test");
        frame.dispose();
    }
});

推荐答案

您可以使用请参见无效windowClosing(WindowEvent e)和 WindowAdapter类.
