推荐答案

好的，为此你需要2个JFrame。第一个是按钮和所有内容，第二个是弹出的按钮。您将有3个类： Main ， classWhere1stJframeis ， ClassWhere2ndJframeis 。

Ok so,for this you will need 2 JFrames. First one is where the buttons and everything is and the second one is the one that will popup. You will have 3 classes: Main, classWhere1stJframeis, ClassWhere2ndJframeis.

这是 main ：

package proba;

import javax.swing.JFrame;

public class mejn {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        Frame1 frejm = new Frame1();
        frejm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frejm.setVisible(true);
        frejm.setSize(250, 300);
    }
}

这是 Frame1 ：

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;

public class Frame1 extends JFrame {
    JFrame Frame = new JFrame();
    JButton Button1 = new JButton();

    public Frame1()
    {
        super("The title");

        Frame = new JFrame();
        Button1 = new JButton();
        Frame.add(Button1);

        thehandler handler = new thehandler();
        Button1.addActionListener(handler);
    }


    private class thehandler implements ActionListener
    {
        public void actionPerformed(ActionEvent event)
        {
            if(event.getSource()==Button1)
            {
                Frejm2 frejm = new Frejm2();
                frejm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frejm.setVisible(true);
            }
        }
    }
}

这个是第2帧：

import javax.swing.JFrame;

public class Frejm2 extends JFrame {
    JFrame Frame2 = new JFrame();

    public Frejm2()
    {
        super("Title");
    }
}
