Buttons and actions

KitFormButton

Button that emits a typed form intent.

Button that emits a typed form intent.
Native screenshot of the same example, rendered with Skia.

Set action to FormAction.submit or .reset and handle form-action. Build the domain payload in your controller.

Activation emits the current intent without submitting or resetting fields itself. busy and disabled come from KitButton.

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.
