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-examples -- button

#Import

use gpui_kit::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.
