How to use the reprounzip-qt.reprounzip_qt.reprounzip_interface.FileStatus function in reprounzip-qt

def __init__(self, directory):
        self.directory = directory
        with open(os.path.join(directory, 'config.yml')) as fp:
            config = yaml.safe_load(fp)

        self.files = [FileStatus(f['name'], f['path'],
                                 f.get('read_by_runs'),
                                 f.get('written_by_runs'))
                      for f in config.get('inputs_outputs') or []]
        logger.info("Loaded %d files from the configuration", len(self.files))
        self._refresh()
