Choices and values

KitSegmentedControl

Compact exclusive choice presented as segments.

Compact exclusive choice presented as segments.
Native screenshot of the same example, rendered with Skia.

Supply the controller’s ChoiceRow values, generation and active-token. Forward navigate and activate, and choose ChoiceFlow.left-to-right or .right-to-left for navigation.

Selected segments use primary intent and expose a radio role. Shared focus and controlled selection remain distinct; labels can wrap.

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.
