使用 Java GUI 将事件处理程序插入到映像中



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。我添加了图像,然后尝试将其插入此容器中,但它显示错误。您能否告诉我哪种方法是在 Java 中插入图像,然后将侦听器添加到该图像或事件处理程序的正确方法?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); 
    }
}
下面是

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();
    }
}
