KitMenuBar

Horizontal bar of stable-identity navigation actions.

Horizontal bar of stable-identity navigation actions.
Native screenshot of the same example, rendered with Skia.

Supply OptionRow and SelectState from the controller and acknowledge activations by token and generation. Use it for a row of actions or destinations.

Left and right arrows request previous and next steps. Horizontal scrolling reveals the active item when the bar exceeds available width.

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.

Types and variants

Names below use Slint syntax. Shared Rust domain types live in slint_kit; presentation enums come from the Rust types generated by Slint.

Type Declaration
enum CloseReason escape, outside-press, system-back, trigger-toggle, programmatic, host-closed
enum ControlSize compact, medium, comfortable
enum NavigationStep next, previous, first, last, page-next, page-previous
struct OptionRow token: int, generation: int, label: string, description: string, disabled: bool
enum SelectionAvailability absent, available, unavailable
struct SelectionRef present: bool, token: int
struct SelectState selection-availability: SelectionAvailability, selected: SelectionRef, active: SelectionRef, open: bool, active-index: int, generation: int
