libtmux.Client.attached_window(self) -> Window | None
```

Return the :class:`Window` this client is currently viewing.

Re-reads the client from [`list-clients`](/en/tmux/latest/manual/list-clients/), looks up its attached
session, and returns that session's :attr:`~libtmux.Session.active_window`.
Returns ``None`` when no live attached session can be resolved.
