Slint Kit Documentation

Times and zones

KitZonedDateTimeField

Date, local-time and zone input with explicit ambiguity resolution.

Date, local-time and zone input with explicit ambiguity resolution.
Native screenshot of the same example, rendered with Skia.

Bind all three texts and handle resolve-requested(ZonedDateTimeDraft) with an IANA zone resolver. Project resolution and resolution-message, then handle ambiguity-chosen when required.

ZonedTimePresentation distinguishes unresolved, unique, ambiguous, nonexistent and invalid-zone. Ambiguity offers AmbiguousTimeChoice.earlier or .later; no occurrence is silently chosen.

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 AmbiguousTimeChoice earlier, later
struct CivilDateView year: int, month: int, day: int
enum ClockFormat twenty-four-hour, twelve-hour
enum ControlSize compact, medium, comfortable
enum FieldAccess editable, read-only, disabled
struct LocalDateTimeView date: CivilDateView, time: LocalTimeView
struct LocalTimeView hour: int, minute: int, second: int
enum TimePrecision minute, second
struct ZonedDateTimeDraft date: string, time: string, zone: string
enum ZonedTimePresentation unresolved, unique, ambiguous, nonexistent, invalid-zone
