ToastOverlay

A widget showing toasts above its content.

<picture> <source srcset="toast-overlay-dark.png" media="(prefers-color-scheme: dark)"> <img src="toast-overlay.png" alt="toast-overlay"> </picture>

Much like [class@Gtk.Overlay], `AdapToastOverlay` is a container with a single main child, on top of which it can display a [class@Toast] , overlaid. Toasts can be shown with [method@ToastOverlay.add_toast].

See [class@Toast] for details.

CSS nodes

``` toastoverlay ├── [child] ├── toast ┊ ├── widget ┊ │ ├── [label.heading] │ ╰── [custom title] ├── [button] ╰── button.circular.flat ```

`AdapToastOverlay`'s CSS node is called `toastoverlay`. It contains the child, as well as zero or more `toast` subnodes.

Each of the `toast` nodes contains a `widget` subnode, optionally a `button` subnode, and another `button` subnode with `.circular` and `.flat` style classes.

The `widget` subnode contains a `label` subnode with the `.heading` style class, or a custom widget provided by the application.

Accessibility

`AdapToastOverlay` uses the `GTK_ACCESSIBLE_ROLE_TAB_GROUP` role.
