Form structure

KitFieldSet

Form group named by a visible and accessible legend.

Set legend and add related fields as children. Use it for an address, a preference group or a coherent domain section.

The legend supplies the accessible groupbox name. Children remain in a column with field spacing.

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.
