# facet_gtk

> **Not recommended on v0.0.27.** This version is a macOS / AppKit release. Other platforms exist in the tree; do not ship on them yet. See the [manual overview](/docs).

facet's GTK 4 backend: the Linux counterpart of [`facet_appkit`](/docs/packages/facet_appkit). It fills the same `Renderer` vtable. facet owns the tree and layout; this package maps each kind to a typed `gtk4` widget.

**Status: type-checked, not run.** `cpc check` is clean in this package's files. It links `libgtk-4`, so it has not been built or run in the compiler checkout. `facet_appkit` is the reference implementation.

```cplus
import "facet_gtk/facet_gtk" as backend;
```

Install the backend, then `runtime::App::run` as on macOS. Real: label, button, identity. Partial: text area. For the generated GTK types themselves, see [gtk4](/docs/packages/gtk).
