Hyperlink in JTextpane without HTMLEditorKit?

Question

Hi,
how is it possible to insert a hyperlink without HTMLEditorKit, simply with a StyledDocument ?
private void addCustomStylesToDocument(StyledDocument doc) {
Style def = StyleContext.getDefaultStyleContext().getStyle(StyleContext.DEFAULT_STYLE);
Style regular = doc.addStyle("regular", def);
StyleConstants.setFontFamily(def, "Arial");
Style s = doc.addStyle("link", regular);
StyleConstants.setUnderline(s, true);
StyleConstants.setBold(s, true);
StyleConstants.setForeground(s, Color.BLUE);
How is it possible to add the hyperlinkListener to a style?

The way I do this is to create a child style for every link containing a key of my own making that maps to the url ref. Then you need a MouseMotionListener to do the hand cursor and a MouseListener for clicks.
  void mouseMoved(MouseEvent me)
       JTextComponent jt = (JTextComponent)me.getComponent();
       int pos = jt.viewToModel(me.getPoint());
       if (pos >= 0)
            StyledDocument d = (StyledDocument)jt.getDocument();
            Element el = d.getCharacterElement(pos);
            AttributeSet as = el.getAttributes();
            if (as.getAttribute(urlRefKey) != null)
              jt.setCursor(linkCursor__);
         else
            jt.setCursor(defaultCursor__);
  }Sorry about the tabbing. In MouseListener.mouseClicked(MouseEvent) call the above code (which you factored out) and if you are over a URL then get the ref from the attributes and launch your browser...
