Checkbox

A checkbox component for binary choices. Supports labels, disabled state, and different sizes.

Use on_change for requested values. The owner stores the value and calls cx.notify(). The existing on_click name remains a compatibility alias; setting either replaces the same handler, so the last call wins.

#Import

use gpui_kit::component::checkbox::Checkbox;

#Usage

#Basic Checkbox

Checkbox::new("my-checkbox")
    .label("Accept terms and conditions")
    .checked(false)
    .on_change(|checked, _, _| {
        println!("Checkbox is now: {}", checked);
    })

The on_change callback is triggered when the user toggles the checkbox, receiving the new checked state.

#Controlled Checkbox

struct MyView {
    is_checked: bool,
}

impl Render for MyView {
    fn render(&mut self, _: &mut Window, cx: &mut Context<Self>) -> impl IntoElement {
        Checkbox::new("checkbox")
            .label("Option")
            .checked(self.is_checked)
            .on_change(cx.listener(|view, checked, _, cx| {
                view.is_checked = *checked;
                cx.notify();
            }))
    }
}

#Different Sizes

Checkbox::new("cb").text_xs().label("Extra Small")
Checkbox::new("cb").text_sm().label("Small")
Checkbox::new("cb").label("Medium") // default
Checkbox::new("cb").text_lg().label("Large")

#Disabled State

Checkbox::new("checkbox")
    .label("Disabled checkbox")
    .disabled(true)
    .checked(false)

#Without Label

Checkbox::new("checkbox")
    .checked(true)

#Custom Tab Order

Checkbox::new("checkbox")
    .label("Custom tab order")
    .tab_index(2)
    .tab_stop(true)
