    // Gjs wrapper for gtk_tree_model_filter_convert_path_to_child_path()
}

Converts filter_path to a path on the child model of filter. That is, filter_path points to a location in filter. The returned path will point to the same location in the model not being filtered. If filter_path does not point to a location in the child model, null is returned.
