Icon

A flexible icon component that renders SVG icons from the built-in icon library. Icons are based on Lucide.dev and support customization of size, color, and rotation. The component requires SVG files to be provided by the user in the assets bundle.

Import

use gpui_component::{Icon, IconName};

Usage

Basic Icon

// Using IconName enum directly
IconName::Heart

// Or creating an Icon explicitly
Icon::new(IconName::Heart)

Icon with Custom Size

// Predefined sizes
Icon::new(IconName::Search).xsmall()   // size_3()
Icon::new(IconName::Search).small()    // size_3p5()
Icon::new(IconName::Search).medium()   // size_4() (default)
Icon::new(IconName::Search).large()    // size_6()

// Custom pixel size
Icon::new(IconName::Search).with_size(px(20.))

Icon with Custom Color

// Using theme colors
Icon::new(IconName::Heart)
    .text_color(cx.theme().red)

// Using custom colors
Icon::new(IconName::Star)
    .text_color(gpui::red())

Rotated Icons

use gpui::Radians;

// Rotate by radians
Icon::new(IconName::ArrowUp)
    .rotate(Radians::from_degrees(90.))

// Transform with custom transformation
Icon::new(IconName::ChevronRight)
    .transform(Transformation::rotate(Radians::PI))

Custom SVG Path

// Using a custom SVG file from assets
Icon::new(Icon::empty())
    .path("icons/my-custom-icon.svg")

Icon Sizes

The Icon component supports several predefined sizes:

Size Method CSS Class Pixels
Extra Small .xsmall() size_3() 12px
Small .small() size_3p5() 14px
Medium .medium() (default) size_4() 16px
Large .large() size_6() 24px
Custom .with_size(px(n)) - n px

SVG Asset Requirements

Important: SVG files must be provided by the user in the assets bundle. The component expects SVG files to be located in the icons/ directory relative to your assets root.

For example, if you want to use IconName::Heart, you need to provide:

  • icons/heart.svg in your assets bundle

The component automatically maps icon names to their corresponding SVG file paths:

  • IconName::ArrowUpicons/arrow-up.svg
  • IconName::GitHubicons/github.svg
  • IconName::CircleCheckicons/circle-check.svg

Notes

  • Icons are rendered as SVG elements and support full CSS styling
  • The default size matches the current text size if no explicit size is set
  • Icons are flex-shrink-0 by default to prevent unwanted shrinking in flex layouts
  • All icon paths are relative to the assets bundle root
  • Icons from Lucide.dev are designed to work well at 16px and scale nicely to other sizes
