如何在推送JButton时关闭GUI [英] How to close a GUI when i push a JButton

问题描述

有谁知道如何让jbutton关闭gui？我认为它就像 System.CLOSE（0）; 但是没有用。它也可以是 exitActionPerformed（evt）; ，但这也不起作用。只需要一行代码即可。

Does anyone know how to make a jbutton close a gui? I think it is like System.CLOSE(0); but that didnt work. it also could be exitActionPerformed(evt);, but that didn't work either. just the line of code will work.

编辑：别介意人。答案是 System.exit（0）; 。感谢您的帮助！

never mind guys. the answer was System.exit(0);. thanks for the help though!

推荐答案

添加按钮：

JButton close = new JButton("Close");

添加一个ActionListener：

Add an ActionListener:

close.addActionListner(new CloseListener());

为实现ActionListener接口的Listener添加一个类并覆盖其主函数：

Add a class for the Listener implementing the ActionListener interface and override its main function:

private class CloseListener implements ActionListener{
    @Override
    public void actionPerformed(ActionEvent e) {
        //DO SOMETHING
        System.exit(0);
    }
}

这可能不是最好的方式，但它是一个指向开始。例如，该类可以公开，而不是另一个类中的私有类。

This might be not the best way, but its a point to start. The class for example can be made public and not as a private class inside another one.
