Question

我正在尝试在JEditorPane中显示可点击链接列表。这是我的代码：

import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.event.HyperlinkEvent;
import javax.swing.event.HyperlinkListener;
import javax.swing.text.BadLocationException;
import javax.swing.text.Document;
import javax.swing.text.Style;
import javax.swing.text.html.HTMLEditorKit;
import javax.swing.text.html.StyleSheet;


public class GUI extends JFrame{
    JEditorPane editorpane=new JEditorPane();
    //this is the constructor
    GUI(){
        JFrame frame=new JFrame("Frame");

        frame.add(editorpane);
        JScrollPane scroll=new JScrollPane(editorpane);

        editorpane.setContentType("text/html");
        editorpane.setEditable(false);
        editorpane.setText("<html><body>Test <a href='http://www.java.net'>"
+ "www.java.net</a></body></html>");
        StyleSheet css = ((HTMLEditorKit)
        editorpane.getEditorKit()).getStyleSheet();
        Style style = css.getStyle("body");
        editorpane.addHyperlinkListener(new HyperlinkListener() {
        public void hyperlinkUpdate(HyperlinkEvent e) {
        if (e.getEventType() ==
        HyperlinkEvent.EventType.ACTIVATED) {
        System.out.println("Open browser: " + e.getURL());
        }
        }
        });
        frame.setSize(512, 342);
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.getContentPane().add(scroll);
        frame.show();
    }
    public void append(String s) {
    try{
        Document doc = editorpane.getDocument();
        doc.insertString(doc.getLength(), "\n", null);
        doc.insertString(doc.getLength(), s, null);

    }
    catch(BadLocationException exc){
    }
    }
    //main method
    public static void main(String args[]){

    GUI gui=new GUI();
    gui.append("<html><body>Test <a href='http://www.java.net'>"
+ "www.java.net</a></body></html>");


    }
}

当我在构造函数中使用setText（）方法时，它显示了一个可单击的链接，但是当我尝试使用append（）显示其他链接时;方法它显示html标签以及文本，它不会使我的网址成为超链接。任何想法，为什么它不兼容追加？

使用HTMLEditorKit的任一方法

public void insertHTML(HTMLDocument doc, int offset, String html,
               int popDepth, int pushDepth,
               HTML.Tag insertTag)

HTMLDocument的方法

public void insertAfterEnd(Element elem, String htmlText)
public void insertAfterStart(Element elem, String htmlText)
public void insertBeforeStart(Element elem, String htmlText
public void insertBeforeEnd(Element elem, String htmlText)
