java - 使用 Java GUI 将事件处理程序插入图像中

Question

我想插入一个图像，然后想使用 Java GUI 向该图像添加一个事件。我添加图像，然后尝试将其插入到此容器中，但显示错误。您能否告诉我在 Java 中插入图像然后向该图像或事件处理程序添加监听器的正确方法是什么？或者如果使用容器来处理图像是正确的方法。我该怎么做？

这是我的代码:

import java.awt.*;
import java.awt.event.*;
import javax.swing.event.*;
import javax.swing.*;
import java.util.Random;

public class Back extends JFrame { 
    private Container pane;
    public Back() {
        super("title");
        setLayout(null);

        Icon i=new ImageIcon(getClass().getResource("1.png"));
        pane=new Container();

        thehandler hand=new thehandler(); //konstruktori i handler merr 
                                          //nje instance te Background
    }

    private class thehandler implements ActionListener {
        public void actionPerformed(ActionEvent event) {

        }
    }

    public static void main(String[] args) {
        Back  d = new Back() ;

        d.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        d.getContentPane().setBackground(Color.GREEN);
        d.setSize(700,500);

        d.setVisible(true); 
    }
}

这是使用 JButton 制作可点击按钮的示例

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class GUITemplate {
    JFrame myMainWindow = new JFrame("Title");
    JPanel  firstPanel = new JPanel();

    private void runGUI() {
        myMainWindow.setBounds(10, 10, 400, 400);
        myMainWindow.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        myMainWindow.setLayout(new GridLayout(1,1));
        createFirstPanel();
        myMainWindow.getContentPane().add(firstPanel);
        myMainWindow.setVisible(true);
    }

    private void createFirstPanel() {
        firstPanel.setLayout(new FlowLayout());

        ImageIcon image1 = new ImageIcon("YourImage.ImageFileType");
        Image image2 = image1.getImage().getScaledInstance(300,300,0);
        ImageIcon image3 = new ImageIcon(image2);

        JButton jB = new JButton(image3);
        jB.addActionListener(new TheHandler());
        firstPanel.add(jB);
    }

    private class TheHandler implements ActionListener { //Changed thehandler to TheHandler
        public void actionPerformed(ActionEvent event) { //because it is a class
            //Do Something
        }
    }

    public static void main(String[] args) {
        GUITemplate gt = new GUITemplate();
        gt.runGUI();
    }
}
