Icons

Register the assets

HeroGpuiAssets embeds the herogpui/icons/*.svg files used by checkmarks, chevrons, clear buttons, and other built-in chrome. Pass it to with_assets before you run the app:

1gpui_platform::application()
2    .with_assets(HeroGpuiAssets)
3    .run(|cx| { /* open windows */ });

If your app already has an asset source, wrap it so both sets resolve. Components keep working, and your own paths stay available:

1gpui_platform::application()
2    .with_assets(HeroGpuiAssets::with_fallback(MyAppAssets))
3    .run(|cx| { /* both icon sets resolve */ });

Draw an icon

Paths live on herogpui::prelude::icons. Size and color are GPUI style methods — icons follow the theme when you read cx.colors():

1use herogpui::prelude::{icons, ActiveTheme};
2use gpui::{px, svg};
3
4svg()
5    .size(px(16.))
6    .path(icons::PLUS)
7    .text_color(cx.colors().foreground)

Put the svg ahead of a label when you compose a Button. Icon-only buttons use is_icon_only(true) so the control stays square.
