Java 带有自定义UI的JSpinner

我正在开发定制设计的swing base应用程序。任务之一-自定义微调器控件。我想实现这样的目标：

我的主要问题是微调器控件与其边界重叠：
创建微调器的代码：

public class GolfSpinner extends JSpinner {

    public GolfSpinner() {
        setBorder(new LineBorder(new Color(Colors.INPUT_BORDER.getR()
                , Colors.INPUT_BORDER.getG(), Colors.INPUT_BORDER.getB()), 1, true));
        setEditor(new Editor(this));
        setUI(new GolfSpinnerUI());
    }

    private class GolfSpinnerUI extends BasicSpinnerUI {

        @Override
        protected Component createPreviousButton() {
            Component component = createButton(Icons.ARROW_DOWN.getUrl());
            super.createPreviousButton();
            if (component != null) {
                installPreviousButtonListeners(component);
            }
            return component;
        }

        @Override
        protected Component createNextButton() {
            Component component = createButton(Icons.ARROW_UP.getUrl());
            if (component != null) {
                installNextButtonListeners(component);
            }
            return component;
        }

        private Component createButton(String url) {
            BufferedImage icon = null;
            try {
                icon = ImageIO.read(new File(url));
            } catch (IOException e) {
                System.err.println(e.getMessage());
            }
            if (icon != null) {
                JButton arrowButton = new JButton(new ImageIcon(icon));
                arrowButton.setBackground(new Color(Colors.APP_PANEL_BACKGROUND.getR()
                        , Colors.APP_PANEL_BACKGROUND.getG(), Colors.APP_PANEL_BACKGROUND.getB()));
                arrowButton.setBorderPainted(false);
                arrowButton.setPreferredSize(new Dimension(icon.getWidth() + 15, icon.getHeight() + 5));
                return arrowButton;
            } else {
                return null;
            }
        }

    }

    private class Editor extends JPanel implements ChangeListener {

        private JLabel label = new JLabel();

        private Editor(JSpinner spinner) {
            setLayout(new FlowLayout(FlowLayout.LEADING));
            label.setForeground(Color.BLACK);
            setBackground(Color.WHITE);
            setBorder(new EmptyBorder(5, 6, 5, 0));
            add(label);
            spinner.addChangeListener(this);
        }

        @Override
        public void stateChanged(ChangeEvent e) {
            JSpinner spinner = (JSpinner) e.getSource();
            label.setText(spinner.getValue().toString());
        }
    }
}

我曾尝试更改微调器的首选大小，但没有帮助。

您可能想看看这些格子是如何做到的

import java.awt.*；
导入java.awt.event.ActionEvent；
导入java.awt.event.ActionListener；
导入javax.swing.*；
类SwingSpinnerLook{
公共静态void main（字符串[]args）{
Runnable r=新的Runnable（）{
@凌驾
公开募捐{
最终的JPanel gui=新的JPanel（新的BorderLayout（））；
JSpinner微调器=新的JSpinner微调器(
新喷丝头型号（10,1100,1）；
添加（微调器、边框布局、线条结束）；
最终UIManager.LookAndFeelInfo[]plafInfos=
UIManager.getInstalledLookAndFeels（）；
字符串[]plafNames=新字符串[plafInfos.length]；
对于（int ii=0；ii谢谢你的建议！我会检查它，如果你想要设计-发布代码。现在我通过在箭头按钮上使用MatteBorder找到了临时解决方案。它不是完美的，但总比没有好。
