# LibTmux::Async::Server::query_panes

- **Module:** LibTmux::Async
- **Package:** LibTmux-Async
- **Language:** Perl
- **Kind:** method
- **Source:** https://github.com/libtmux/libtmux-perl/blob/352715a4fa66a96eed7763b90daaa536aa2f121d/packages/async/lib/LibTmux/Async/Server.pm#L68

```
sub query_panes($self, %args)
```

See [`"query_panes" in LibTmux::Server`](/en/perl/latest/reference/libtmux-server-query_panes/) for arguments, returned value, and completion. Its observer runs inline in void context; a returned [Future](https://metacpan.org/pod/Future) is ignored. Cancellation before the decision suppresses it. If the observer cancels its query or calls [`"close"`](/en/perl/latest/reference/libtmux-async-server-close/), cancellation takes precedence over subsequent return or exception delivery. Continue driving the loop until close cleanup completes.
