JoptionPane多选和可滚动选项 [英] JoptionPane multi select and srollable option

问题描述

我是JoptionPane的新手，有没有什么方法可以使我拥有多重选择和可滚动功能.请在下面找到我的代码.

I'm new to JoptionPane is there any method that i can have multi select and scrollable feature. Please find my code below.

String bigList[] = new String[100];

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

用于滚动，我正在使用

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

对于使用

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

问题是我需要结合滚动和多选选项这两个功能，任何人都可以为我提供适当的代码

  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();
