+Top-level Windows
+=================
+When a component is shown on screen via a GUI toolkit, its :attr:`window` trait
+contains an instance of :class:`~.AbstractWindow` which serves as a delegate
+between the underlying window system and the component.
+
+For the most part, code doesn't need to interact with the underlying window.
+However one common exception is tools which want to set a custom cursor. This
+is accomplished via the :py:meth:`set_pointer` method.
+
+AbstractWindow
+--------------
+The following methods are the public interface of :class:`AbstractWindow`.
