Understanding the TreeModel[^]

You could check your node whether it is a file and then extract the file type ending. With that you can retrieve the file icon by searching for the program that supports this file from the OS:

Java

final int iSplit = strFileName.lastIndexOf('.') + 1;
  if (0 < iSplit) {
    final String strExtension = strFileName.substring(iSplit);
    if (null != strExtension) {
      final Program oProgram = Program.findProgram("." + strExtension);
      if (null != oProgram) {
        return new Image(Display.getCurrent(), oProgram.getImageData());
      }
    }
  }
