Choices and values

KitRating

Score selection with an explicit clear action.

Score selection with an explicit clear action.
Native screenshot of the same example, rendered with Skia.

Supply scores: [ChoiceRow], generation and active-token from the rating controller. Handle choose(token, generation) separately from clear-requested.

The presentation composes KitSegmentedControl and a clear action. No rating remains an explicit domain state, distinct from the first score.

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.
