JLabel中包含的超链接的java添加事件

1 年，5 月 Questions & Answers 1114

我有一个jlabel显示内容，然后我在内容上添加一个超链接include。使用标签。我有一个问题，如何用户可以点击这个超链接，鼠标点击监听器的工作。这是我的密码：

String languages="<html> Deutsch, English (All), English (United Kingdom), Bahasa Indonesia, Italiano <a href=\"\"> edit</a> </html>"; GUIConstants.ELM_ALIGN_RIGHT), 240, 0));*/ JLabel lblLanguage= new JLabel(); lblLanguage.setFont((new Font("Arial", Font.PLAIN, 12))); lblLanguage.setText(languages);

如果用户单击编辑链接，弹出窗口将显示。否则，单击内容上的文本，它将不起作用。谢谢

我认为这就是你想要实现的目标：

import java.awt.BorderLayout;   
import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.event.HyperlinkEvent;
import javax.swing.event.HyperlinkListener;

public class HtmlMsg {

    public static void main(String[] args) {

        JFrame frame = new JFrame("Message with HTML link");

        String languages="<html> Deutsch, English (All), English (United Kingdom), "
                + "Bahasa Indonesia, Italiano <a href=\"\">  edit</a> </html>";

        frame.getContentPane().add( panelWithHtmlListener(languages));
        frame.pack();
        frame.setVisible(true);
    }

    /**
     * 
     * @param msg
     *       to be displayed. Should contain HTML or html tag.
     *
     * @return
     *       Returns a panel with an HTML listener, displaying msg.
     */
    private static JPanel panelWithHtmlListener(String msg){

        JEditorPane jEditorPane = new JEditorPane("text/html", msg);
        jEditorPane.setEditable(false);
        jEditorPane.setOpaque(false);

        HyperlinkListener listener = new HyperlinkListener() {
            @Override
            public void hyperlinkUpdate(HyperlinkEvent hyperLink) {

                if (HyperlinkEvent.EventType.ACTIVATED.
                                equals(hyperLink.getEventType())) {
                    try {
                       //respond to html link clicked
                        JOptionPane.showMessageDialog(null, "HTML has been clicked !!" );
                    }
                    catch (Exception ex) { ex.printStackTrace();}
                }
            }

        };

        jEditorPane.addHyperlinkListener(listener);

        JPanel jPanel = new JPanel();
        jPanel.setLayout(new BorderLayout(5, 5));
        jPanel.add(jEditorPane,  BorderLayout.CENTER);

        return jPanel;
    }   
}
