我怎样才能将这样的图像放到slavePanelJPanel的顶部和顶部,调整JButtons看起来像图像但是按钮正确缠绕？(现在它们形成一排,四列)

  //
  // Shot Gun mover up/down/left/right, middle on is for zoom
  //
  public void GunMover(JPanel configPanel) throws IOException {

    // Master Panel - holds everything
    JPanel masterPanel = new Panel();
    masterPanel.setLayout(new SpringLayout());

    // Slave Panel - with image background 
    JPanel slavePanel = new Panel();
    slavePanel.setLayout(new SpringLayout());

    // Row 1
    final JButton ptzLeft = new JButton("<");       
    masterPanel.add(ptzLeft, BorderLayout.WEST);

    // Row 2
    final JButton ptzRight = new JButton(">");   
    masterPanel.add(ptzRight, BorderLayout.CENTER);    

    // Row 3
    final JButton ptzUp = …

这是 JFrame

package client.connection;

import java.awt.Dimension;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import javax.swing.JFrame;


class DrawFrameRemoteControl extends JFrame
{
    private DrawPanelRemoteControl imagePanel;
    private ClientRemoteControlConnection clientRemoteControlConnection;
    private ObjectInputStream clientInputStream;
    private ObjectOutputStream clientOutputStream;
    private Dimension imageDimension;
    private Dimension serverDimension;

    public DrawFrameRemoteControl(Dimension imageDimension,ClientRemoteControlConnection clientRemoteControlConnection,ObjectInputStream clientInputStream,ObjectOutputStream clientOutputStream,Dimension serverDimension)
    {
        super("Remote Desktop Control");

        this.clientRemoteControlConnection=clientRemoteControlConnection;
        this.clientInputStream=clientInputStream;
        this.clientOutputStream=clientOutputStream;
        this.imageDimension=imageDimension;
        this.serverDimension=serverDimension;

        imagePanel=new DrawPanelRemoteControl(imageDimension);
        add(imagePanel);


        setSize(imageDimension.width,imageDimension.height);
        setResizable(false);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setVisible(true);
        setLocationRelativeTo(null);
    }

    void drawNewImageGrayscale(byte[] array)
    {
        imagePanel.setNewImageGrayscale(array);
        imagePanel.repaint();
    }
}

这是扩展的JPanel类 -

import java.awt.Toolkit; …

我有一个图像列表.我需要在框架中添加小缩略图.我目前有框架SpringLayout.如何使用滚动窗格在某些网格中添加缩略图.照片列表可能很大,所以我需要一个滚动窗格.我不知道如何解决这个问题SpringLayout.我知道如何添加缩略图; 真正的问题我如何才能显示缩略图网格SpringLayout.
