Progress

Composable track and indicator parts for reporting task completion.

Like every gpui-base primitive, Progress supplies behavior and semantic structure without imposing a product visual language. Apply GPUI styles and compose the exported parts to match your design system.

#Example

The single native Cargo entrypoint selects this primitive from the shared showcase implementation. The same showcase is compiled once for the WASM preview above.

cargo run -p gpui-base --example components -- progress

#Import

use gpui_kit::base::{Progress, ProgressIndicator, ProgressTrack};

#Anatomy and API

The example composes Progress, ProgressIndicator, ProgressTrack. GPUI’s standard styling and event traits provide presentation; these base types provide the interaction structure.

The authoritative module is components/progress.rs. Native and browser previews compile this same file.

#State and events

Set the value on Progress; size and position ProgressIndicator inside ProgressTrack.

Keep controlled state on the parent render type or in a GPUI entity. Update it in callbacks and call cx.notify(); do not recreate persistent entities during every render.

#Complete Rust example

The complete implementation used by the runnable showcase is embedded directly from Rust source:

use gpui::{IntoElement, ParentElement as _, Styled as _, div, px};
use gpui_base::{Progress, ProgressIndicator, ProgressTrack};

use super::super::BaseShowcase;

impl BaseShowcase {
    pub(in super::super) fn progress(&self) -> impl IntoElement {
        div()
            .w_64()
            .flex()
            .flex_col()
            .gap_2()
            .text_xs()
            .child(
                div()
                    .flex()
                    .justify_between()
                    .child("Uploading assets")
                    .child("68%"),
            )
            .child(
                Progress::new("example-progress").value(68.).child(
                    ProgressTrack::new()
                        .w_full()
                        .h(px(7.))
                        .border_1()
                        .border_color(super::example_rgb(0x171717))
                        .child(
                            ProgressIndicator::new()
                                .w(px(177.))
                                .h_full()
                                .bg(super::example_rgb(0x171717)),
                        ),
                ),
            )
            .child(
                div()
                    .flex()
                    .justify_between()
                    .text_sm()
                    .text_color(super::example_rgb(0x737373))
                    .child("Optimizing bundle")
                    .child("32%"),
            )
            .child(
                Progress::new("example-progress-secondary")
                    .value(32.)
                    .child(
                        ProgressTrack::new()
                            .w_full()
                            .h(px(6.))
                            .border_1()
                            .border_color(super::example_rgb(0xa3a3a3))
                            .child(
                                ProgressIndicator::new()
                                    .w(px(83.))
                                    .h_full()
                                    .bg(super::example_rgb(0x737373)),
                            ),
                    ),
            )
    }
}

The command above supplies application initialization, window creation, and shared BaseShowcase state.

#Accessibility

Expose task label and numeric value; use indeterminate state only when progress is unknown.

#Notes

Use stable element IDs where accepted. Verify focus, hover, active, selected, disabled, reduced-motion, and high-contrast appearances in the consuming design system.
