## Built-in icons [#built-in-icons]

Controls such as `MacCheckbox`, `MacSwitch`, `MacPopUpButton`, `MacSearchField`, and `MacStepper` include their own vector graphics:

* Check marks and dashes for checkbox states
* Switch thumb and track shapes
* Pop-up button chevrons
* Search field magnifying glass and clear button
* Stepper up/down arrows

These are implemented as regular GPUI [`Image`](https://docs.rs/gpui/latest/gpui/struct.Image.html) elements with embedded SVG bytes, so they scale cleanly at every control size and DPI.

## No asset setup required [#no-asset-setup-required]

Because every glyph is compiled into the crate binary, there is no `assets/` folder to configure and no font file to load. This keeps both native and WebAssembly builds self-contained.

## Custom icons [#custom-icons]

For your own application icons, use GPUI's native image support or any GPUI-compatible icon library. You can style custom icons with colors from [`MaccnTheme`](./theme):

```rust
use maccn::theme::ThemeExt as _;

let theme = cx.theme();
let icon_color = theme.label_secondary;
```
