Gtk.TreeModelSort.prototype.convert_child_path_to_path

function convert_child_path_to_path(child_path:Gtk.TreePath):Gtk.TreePath {
    // Gjs wrapper for gtk_tree_model_sort_convert_child_path_to_path()
}

Converts child_path to a path relative to tree_model_sort. That is, child_path points to a path in the child model. The returned path will point to the same row in the sorted model. If child_path isn't a valid path on the child model, then null is returned.
