Gtk.TreeModelSort.prototype.convert_path_to_child_path

function convert_path_to_child_path(sorted_path:Gtk.TreePath):Gtk.TreePath {
    // Gjs wrapper for gtk_tree_model_sort_convert_path_to_child_path()
}

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