KitDurationField
Decimal field for a duration expressed in an explicit unit.
Name the canonical unit in suffix, such as seconds or minutes. Have the controller validate the exact duration through inherited callbacks.
It does not interpret a clock or an hours-and-minutes string. The draft stays decimal text and the domain decides precision and allowed values.
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.
