KitBreadcrumbs

Breadcrumb trail linking parent levels to the current location.

Supply OptionRow values from the root level to the current level. Handle activate(token, generation) to open a parent destination.

The final item is current-location text without an action; preceding items remain named buttons. The bar can scroll horizontally for long paths.

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.
