#### Description [src]

    final class Adw.ToastOverlay : Gtk.Widget
      implements Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget {
      /* No available fields */
    }

A widget showing toasts above its content.

Much like `GtkOverlay`, `AdwToastOverlay` is a container with a single main child, on top of which it can display a `AdwToast`, overlaid. Toasts can be shown with `adw_toast_overlay_add_toast()`.

See `AdwToast` for details.

## CSS nodes

        │   ╰── [custom title]
        ├── [button]
        ╰── button.circular.flat

`AdwToastOverlay`‘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

`AdwToastOverlay` uses the `GTK_ACCESSIBLE_ROLE_TAB_GROUP` role.
