我想用一些JTextArea和JLabel创建一个JOptionPane.showOptionDialog.
问题是对话框太小而我找不到任何解决方案,所以我决定将我的内容放在JScrollPane中.

我看到我必须将我的所有JTextArea和我的JLabel放在JPanel中,因为连续在JScrollPane中添加它们不允许我正确放置视口.

最后一个问题是我的JTextArea正确地包装了单词但是当我有2或3个字母长度的单词时,它们被滚动条隐藏.

SSCCE：

public class myTest extends JFrame
{
        public static void main(String[] args)
        {
            new myTest();
        }
        public myTest()
        {
            String myLongString="Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo.

            String aLittleString="I am a poor little string which is placed at the bottom of a JOptionPane.";
            String[] options = {"OK","NO"}; 

            JLabel titre1 = new JLabel("Title"); 
            JLabel titre2 = new JLabel("Title 2");

            Map<TextAttribute,Integer> attributs = new HashMap<TextAttribute, Integer>();
            attributs.put(TextAttribute.UNDERLINE, TextAttribute.UNDERLINE_ON);
            Font police = new Font("Serif", Font.BOLD, 12).deriveFont(attributs); 

            titre1.setFont(police);
            titre2.setFont(police);

            JTextArea text3 = new JTextArea(myLongString,5,75); 
            text3.setLineWrap(true);
            text3.setWrapStyleWord(true);
            text3.setEditable(false);
            Color back = this.getBackground();
            text3.setBackground(back);
            JTextArea text = new JTextArea(myLongString,5,75); 
            text.setLineWrap(true);
            text.setWrapStyleWord(true);
            text.setEditable(false);
            text.setBackground(back);

            JTextArea text2 = new JTextArea(aLittleString,5,75); 
            text2.setLineWrap(true);
            text2.setWrapStyleWord(true);
            text2.setEditable(false);
            text2.setBackground(back);
            JPanel bas = new JPanel(new BorderLayout());
            JPanel basbas = new JPanel(new BorderLayout());

            bas.add(titre1,BorderLayout.NORTH);
            bas.add(text,BorderLayout.CENTER);
            basbas.add(titre2,BorderLayout.NORTH);
            basbas.add(text2,BorderLayout.CENTER);
            basbas.add(text3,BorderLayout.SOUTH);
            bas.add(basbas,BorderLayout.SOUTH);

            JScrollPane js = new JScrollPane(bas);
            js.setBorder(null);
            js.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
            js.setViewportView(bas);
            JLabel lMessage = new JLabel("A message."); 

            Object[] params = {js,lMessage}; 

            int n = JOptionPane.showOptionDialog(new JFrame(),
                    params,
                    "my dialog", 
                    JOptionPane.YES_NO_OPTION,
                    JOptionPane.QUESTION_MESSAGE,
                    null, 
                    options, 
                    options[0]); 

        }
    }

我读了几个主题,但他们总是在谈论setWrapStyleWord.
我禁用水平滚动条,因为我不想要它,实际上我不想要一个2个字母的滚动条.

在我看来,问题是我使用JPanel构建滚动条但我找不到其他解决方案.

我的帖子或英语的任何反馈也欢迎.

解决方法:

把我的评论回答.请尝试向要添加JScrollPane的JPanel提供一个Empty Border,或者可以向JTextArea添加一个EmptyBorder.
