KitOtpField
One-time code field that retains one native editor.
Bind the draft and use the core OtpLength and OtpAlphabet parsers to validate the complete code. Choose a label describing the expected code.
Character spacing and centering are visual; they do not create a box per character. Paste, selection and undo remain native editor behavior.
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.
