在Java中提供可滚动的图像视图(波形)而不使用ImageIcon的简单方法？

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

class WaveformPanel extends JPanel {
    private int[] waveformData; // 波形数据

    public WaveformPanel(int[] waveformData) {
        this.waveformData = waveformData;
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);

        // 绘制波形图像
        // 使用waveformData绘制波形，具体绘制逻辑根据实际需求实现

        // 示例代码：绘制一条简单的水平线
        g.drawLine(0, getHeight() / 2, getWidth(), getHeight() / 2);
    }

    @Override
    public Dimension getPreferredSize() {
        return new Dimension(800, 400); // 设置面板的首选大小
    }
}

class WaveformViewer extends JFrame {
    public WaveformViewer() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setTitle("Waveform Viewer");

        int[] waveformData = { /* 波形数据 */ };
        WaveformPanel waveformPanel = new WaveformPanel(waveformData);

        JScrollPane scrollPane = new JScrollPane(waveformPanel);
        scrollPane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
        scrollPane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_NEVER);

        setContentPane(scrollPane);
    }
}

public class Main {
    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> {
            WaveformViewer waveformViewer = new WaveformViewer();
            waveformViewer.setSize(800, 600);
            waveformViewer.setVisible(true);
        });
    }
}
