KitToastHost

Transient notification stack supplied by a Rust-owned queue.

Transient notification stack supplied by a Rust-owned queue.
Native screenshot of the same example, rendered with Skia.

Project ToastQueue entries through entries and forward action, dismissal and interaction callbacks. Place the stack in a window region appropriate for your application.

Each entry is rendered by KitToast without a per-delegate timer. The owner decides lifetime, ordering and removal while preserving remaining time after a pause.

Complete example

This complete Slint file is a visual composition used to produce the screenshot above. Internal strings without a label property retain the kit’s default language; system dialogs follow the host platform. Projected state and callbacks requesting a decision need host wiring; the standalone fixture does not supply that controller. Set up the Rust project, then see the typed controller application for working editing, validation and selection.
