KitButton
Labeled button whose busy indicator preserves its natural width.
Set text and handle the inherited activated callback. Use intent for action hierarchy and control-width: ControlWidth.fill to fill a slot.
The text supplies the accessible name when accessible-name is empty. busy visually replaces the label without changing its measurement and blocks activation.
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.
