The get_extents() method if different in PangoCairo. It calculates an extent as a Rectangle, but doesn't return anything. There is a method, get_logical_extents() that returns a Rectangle. Alas, it is not necessarily available after v1.16. Note that Rectangle is not a list but a class with methods for get_x(), get_y(), get_width(), and get_height(), so you cannot iter over it. | The get_extents() method if different in PangoCairo.
