当我按下JButton时如何关闭GUI? [英] How to close a GUI when I push a JButton?

问题描述

有人知道如何使jbutton关闭gui吗?我认为它就像System.CLOSE(0);，但没有用.也可以是exitActionPerformed(evt);，但这也不起作用.只需一行代码即可.

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.

没关系，伙计们.答案是System.exit(0);.谢谢你的帮助！

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，并覆盖其主要功能:

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法，但这是一个起点.例如，该类可以设置为公共类，而不能作为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.
