java - 带有可滚动对象的 JDialog

Question

我正在使用一个组件对象，然后在 Jdialog 中调用，但我想让它可滚动，因为由于组件数量较多，它在屏幕中占用了足够的空间。我找到了许多文本区域滚动的解决方案，但与我无关。

//Object of components
             Object[] Payments = {
            "For Max-cost 14 (Applied to all currencies):", er1,
            "For Max-cost 12 (Applied to all currencies)", er2,
            "For Max-cost 10.5 (Applied to all currencies)",er105,
            "For Max-cost 10 (Applied to all currencies)", er10,                                    
            "For Max-cost 9 (Applied to all currencies)", er9,                                   
            "For Max-cost 8.25 (Applied to all currencies)",er825,
            "For Max-cost 8 (Applied to all currencies)", er8,                                   
            "For Max-cost 7 (Applied to all currencies)", er7,                        
            "For Max-cost 6.75 (Applied to all currencies)",er675,
            "For Max-cost 6 (Applied to all currencies)", er3,
            "For Max-cost 5 (Applied to all currencies)", er6,            
            "For Max-cost 4 (Applied to all currencies)", er4,
            "For Max-cost 3.75 (Applied to all currencies)",er375,
        };
//calling dialog 
JOptionPane.showConfirmDialog(null, Payments, "Set Amount for different job-budget", JOptionPane.OK_CANCEL_OPTION);

这会有所帮助

public static void main(String[] args) {
    ScrollDialog dialog = new ScrollDialog();
    dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
    dialog.setVisible(true);
}

public static class ScrollDialog extends JDialog {
    private JScrollPane scrollPane = new JScrollPane();
    private JPanel innerPane = new JPanel();

    public ScrollDialog() {
        this.setSize(400, 400);
        this.setLocationRelativeTo(null);
        this.getContentPane().setLayout(new BorderLayout());
        this.getContentPane().add(scrollPane, BorderLayout.CENTER);
        this.innerPane.setPreferredSize(new Dimension(100, 800));
        this.scrollPane.setViewportView(innerPane);
    }
}

在“innerPane”中添加您想要的内容。快乐编码:)
