Button

An unstyled, accessible pressable with semantic state and keyboard activation.

Like every gpui-base primitive, Button 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 -- button

Import

use gpui_base::{Button};

Anatomy and API

The example composes Button. GPUI's standard styling and event traits provide presentation; these base types provide the interaction structure.

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

State and events

Activation uses GPUI click handling. Styling for hover, active, focus, and disabled states remains application-owned.

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::relative;

use super::*;

impl BaseShowcase {
    pub(in super::super) fn button(&self) -> impl IntoElement {
        div()
            .flex()
            .items_center()
            .gap_2()
            .child(
                Button::new("primary-button")
                    .px_3()
                    .h_7()
                    .line_height(relative(1.))
                    .flex()
                    .items_center()
                    .text_xs()
                    .border_1()
                    .border_color(super::example_rgb(0x171717))
                    .bg(super::example_rgb(0x171717))
                    .text_color(super::example_rgb(0xffffff))
                    .hover(|style| style.bg(super::example_rgb(0x404040)))
                    .child("Save changes"),
            )
            .child(
                Button::new("secondary-button")
                    .px_3()
                    .h_7()
                    .line_height(relative(1.))
                    .flex()
                    .items_center()
                    .text_xs()
                    .border_1()
                    .border_color(super::example_rgb(0xd4d4d4))
                    .bg(super::example_rgb(0xffffff))
                    .hover(|style| style.bg(super::example_rgb(0xf5f5f5)))
                    .child("Cancel"),
            )
    }
}

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

Accessibility

Provide an accessible name, preserve keyboard activation, and expose disabled state.

Notes

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