java - 在选项卡 Pane 中显示多个图像

Question

有人可以建议我在 jtabbedpane 选项卡中显示多个图像的方法吗？例如，我想显示图像的缩略图 View ，并选择应在其他选项卡中打开的图像？

我已经放置了部分代码来展示我想要的内容。在这里，我绘制了图像，但实际上我想加载这些图像以允许他们选择进行编辑。

import javax.swing.*;
import java.awt.*;
import java.awt.Event.*;
import java.io.File;
import java.awt.image.BufferedImage;
import javax.imageio.ImageIO;
import java.io.IOException;

public class SwindDesign {
    public static void main(String[] args) throws IOException {
    JFrame frame = new JFrame("Split Pain");
    frame.setSize(700, 500);
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setLayout(new GridLayout());

    //panel
    JPanel panel = new JPanel();
    panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
    panel.add(new PicturePanel());

    JTabbedPane jtp = new JTabbedPane();

     jtp.addTab("Set Image", panel);
      jtp.addTab("Compare Image", new JButton());
      frame.add(jtp);

    }
}
class PicturePanel extends JPanel {

File folder = new File("C:/Documents and Settings/All Users/Documents/My Pictures/Sample Pictures");
File[] listOfFiles = folder.listFiles();
ImageIcon[] img ;
JComponent lblimg;
JTabbedPane jtp = new JTabbedPane();
private BufferedImage[] b = new BufferedImage[10];

public PicturePanel() throws IOException {
    for (int i = 0; i < listOfFiles.length; i++) {
        System.out.println("chek panth"+listOfFiles[i].getName().toString());
        b[i] = ImageIO.read(new File("C:/Documents and Settings/All Users/Documents/My Pictures/Sample Pictures/" + listOfFiles[i].getName().toString()));
    }
}

@Override
protected void paintComponent(Graphics g) {
    super.paintComponents(g);
    Graphics2D g2 = (Graphics2D) g;
    int k = 10;
    for (int j = 0; j < listOfFiles.length - 1; j++) {
        g2.drawImage(b[j], k, 0, 100, 100, null);
        k = k + 75;
        }
   }
}

1. 将 JPanel 与 GridLayout 或 GridBagLayout 一起使用来显示 JLabel 列表。
2. 为每个标签设置一张图像，并将一个 MouseListener 附加到每个标签。单击标签后，创建一个带有大图像的新 JPanel 或 JLabel 并将其添加到选项卡
