    // Gjs wrapper for gtk_tree_model_filter_convert_child_iter_to_iter()
}

Sets filter_iter to point to the row in filter that corresponds to the row pointed at by child_iter. If filter_iter was not set, false is returned.

Returns: true, if filter_iter was set, i.e. if child_iter is a valid iterator pointing to a visible row in child model.
