KitSkeleton

Loading shape that reserves space for pending content.

Size it to the expected content and use multiple instances to suggest its structure. Set running from loading activity.

Opacity pulses when animation is active and theme.reduced-motion is false. This placeholder supplies neither progress state nor a loading message.

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.
