showOptionDialog按钮位于不同的行上

Question

无法使OptionDialog中的按钮显示在新行上.它们都出现在一行中,但我想将它们放在不同的行上.

我也尝试设置一个框架来添加到OptionDialog(设置最大宽度),但它对我来说也没有用.

任何想法/帮助/建议赞赏.

Object[] options = { "Button1", "Button2", "Button3", "Button4", 
     "Button5 On a newLine\n\n", "Button 6", "Button 7" };
int x = JOptionPane.showOptionDialog(null, "Choose a button..", "Title",
     JOptionPane.DEFAULT_OPTION, JOptionPane.QUESTION_MESSAGE,
     null, options, options[0]);

Answer 1

考虑这个选择.

import javax.swing.*;

class Options {

    public static void main(String[] args) throws Exception {
        SwingUtilities.invokeLater( new Runnable() {
            public void run() {
                Object[] options = {
                    "Option 1",
                    "Option 2",
                    "Option 3",
                    "Option 4",
                    "Option 5",
                    "Option 6",
                    "Option 7",
                    "None of the above" 
                };
                JComboBox optionList = new JComboBox(options);
                optionList.setSelectedIndex(7);
                JOptionPane.showMessageDialog(null, optionList, "Title",
                     JOptionPane.QUESTION_MESSAGE);
            }
        });
    }
}
