Module progress 

Progress — a non-interactive horizontal bar showing how full a 0.0..=1.0 value is. Shaped like the shadcn / Radix Progress primitive, scaled down to a single progress(value) builder because Aetna progress bars don’t need to advertise their indeterminate or label-bearing state — apps compose those around the bar.

use aetna_core::prelude::*;

struct Storage { used_pct: u32 }

impl App for Storage {
    fn build(&self, _cx: &BuildCx) -> El {
        column([
            row([
                text("Storage").label(),
                spacer(),
                text(format!("{}%", self.used_pct)).muted(),
            ]),
            progress(self.used_pct as f32 / 100.0),
        ])
    }
}

Progress paints the same way as the slider track + fill, minus the thumb. There’s no apply_event because the widget is read-only — apps update the underlying value through whatever channel they own (timer tick, async snapshot, computed metric, …).

Constants

DEFAULT_HEIGHT

Default bar height in logical pixels.

Functions

progress

A horizontal progress bar. value is clamped to 0.0..=1.0; the returned El defaults to filling its container’s width and a fixed DEFAULT_HEIGHT. Override with .height(...) / .width(...) like any El.

progress_indeterminate

Indeterminate horizontal loader — same dimensions as progress, but with a small bar of bar_color sliding back and forth across a muted track on a continuous loop. Use this in progress slots where no completion ratio is available (uploading to a server that doesn’t report bytes-sent, parsing a stream of unknown length, etc.). The runtime keeps the host loop ticking automatically while one is in the tree.
