Feedback and progress

KitProgress

Determinate progress bar expressed as a fraction.

Project progress through value from 0 to 1 and supply a contextual label. Keep exact counters and fraction calculation in the controller.

bounded-value clamps rendering to the interval and the accessible percentage is rounded. The component neither animates invented progress nor manages the task.

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.
