java - JoptionPane 多选和可滚动选项

Question

我是 JoptionPane 的新手，有什么方法可以让我拥有多选和可滚动功能。请在下面找到我的代码。

String bigList[] = new String[100];

        for (int i = 0; i < bigList.length; i++) {
          bigList[i] = Integer.toString(i);
        }

我正在使用滚动

 JOptionPane.showInputDialog(new JFrame(), "Pick a printer", "Input", JOptionPane.QUESTION_MESSAGE,null, bigList, "Titan");

使用多选即时消息

 JList list = new JList(bigList);
        JOptionPane.showMessageDialog(null, list, "Select Test Case (For Multiple Selections Press 'Ctrl') ", JOptionPane.PLAIN_MESSAGE);

问题是我需要结合这两个功能，即滚动和多选选项。任何人都可以为我提供合适的代码。

• 基于 Oracle 教程 How to Make Dialogs - Getting the User's Input from a Dialog

• Swing JComponents(其模型)被指定为使用标准 Java 数据类型

• 例如，有两种模型(从键盘响应数字 0-9)

import java.awt.EventQueue;  
import javax.swing.Icon;  
import javax.swing.JOptionPane;  
import javax.swing.UIManager;  

public class MyOptionPane {  

    public MyOptionPane() {  
        Icon errorIcon = UIManager.getIcon("OptionPane.errorIcon");  
        Object[] possibilities = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};  
        Integer i = (Integer) JOptionPane.showOptionDialog(null,   
                null,  "ShowInputDialog",   
                JOptionPane.PLAIN_MESSAGE, 1,  errorIcon, possibilities, 0);

        // or

        Integer ii = (Integer) JOptionPane.showInputDialog(null,  
                "Select number:\n\from JComboBox", "ShowInputDialog",  
                JOptionPane.PLAIN_MESSAGE, errorIcon, possibilities, "Numbers");  
    }  

    public static void main(String[] args) {  
        EventQueue.invokeLater(new Runnable() {  
            @Override  
            public void run() {  
                MyOptionPane mOP = new MyOptionPane();  
            }  
        });  
    }  
}
