# gobject > **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). The GObject runtime used by the generated GTK stack (`gtk4`, `adwaita`, `glib`, `gio`, …). Handles, signals, and the `str` ↔ C-string bridge live here. ```cplus import "gobject/runtime" as gobject; import "gobject/signal" as signal; import "gobject/bridge" as bridge; ``` Generated by `cpc-bindgen --gobject`. Strings at the C+ surface are `str`; the bridge allocates the NUL-terminated C string. Object handles are non-owning `{ _raw }` wrappers. This is the Linux analog of `objc` for the Apple frameworks.
