在 JFrame 上运行函数关闭

2022-01-24 00:00:00 java swing jframe windowlistener 
void terminate() {}
protected JFrame frame = new JFrame();

当我按下关闭按钮时，如何让 frame 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，但由于某种原因它不打印测试(但是，程序关闭).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

你可以使用addWindowListener:

frame.addWindowListener(new WindowAdapter() {
    public void windowClosing(WindowEvent e) {
        // call terminate
    }
});

参见 void windowClosing(WindowEvent e) 和 类 WindowAdapter 也是.
