JFileChooser feature

Question

Hello all,
I need to know how could I integrate type-ahead feature into JFileChooser. I have been able to put in FileFilter in the JFileChooser dialog but I cant' seem to figure out how to put in type-ahead feature which causes JFileChooser to jump to a file whose corresponding first letter typed by the user.
        final JFileChooser fc = new JFileChooser (lastDirSelected);
        fc.setDialogTitle("Select Children File");
        fc.setFileSelectionMode(JFileChooser.FILES_ONLY);
         javax.swing.filechooser.FileFilter fi =   new javax.swing.filechooser.FileFilter () {
          private String des = "Xml Files (*.xml)";
          public boolean accept (File f) {
            String name = f.getName();
            String temp[] = name.split("\\.");
            int length = temp.length;
            String ext = temp[length-1].toLowerCase();
            if (f.isDirectory()){
              return true;
            if(ext.equals("xml")){
              return true ;
            } else {
              return false;
          public String getDescription () {
            return des;
        fc.setFileFilter(fi);
        fc.setApproveButtonText("Select");
        fc.setApproveButtonMnemonic('S');
        int returnVal = fc.showOpenDialog (this);
        if (returnVal == fc.APPROVE_OPTION) {
            childXmlFile = fc.getSelectedFile ().toString ();
            childInfoFileText.setText (childXmlFile);
         }The above code is a working code but there is little problem as well, fc.setApproveButtonMnemonic('S'); does not underline 'S' in "Select". Anyway this issue does not matter to me much, but if anyone of you could get me any solution or advice or suggestion regarding the type-ahead feature, I would be grateful.

Khurram
