Settings

Since: v0.5.0

The Settings component provides a UI for managing application settings. It includes grouped setting items and pages. We can search by title and description to filter the settings to display only relevant settings (Like this macOS, iOS Settings).

Import

use gpui_component::setting::{Settings, SettingPage, SettingGroup, SettingItem, SettingField};

Usage

Build a settings

Here we have components that can be used to build a settings page.

• Settings - The main settings component that holds multiple setting pages.
• SettingPage - A page of related setting groups.
• SettingGroup - A group of related setting items based on GroupBox style.
• SettingItem - A single setting item with title, description, and field.
• SettingField - Provide different field types like Input, Dropdown, Switch, etc.

The layout of the settings is like this:

Settings
  SettingPage
    SettingGroup
      SettingItem
        Title
        Description (optional)
        SettingField

Basic Settings

use gpui_component::setting::{Settings, SettingPage, SettingGroup, SettingItem, SettingField};

Settings::new("my-settings")
    .pages(vec![
        SettingPage::new("General")
            .group(
                SettingGroup::new()
                    .title("Basic Options")
                    .item(
                        SettingItem::new(
                            "Enable Feature",
                            SettingField::switch(
                                |cx: &App| true,
                                |val: bool, cx: &mut App| {
                                    println!("Feature enabled: {}", val);
                                },
                            )
                        )
                    )
            )
    ])

With Multiple Pages

INFO

When you want default expland a page, you can use default_open(true) on the SettingPage.

Settings::new("app-settings")
    .pages(vec![
        SettingPage::new("General")
            .default_open(true)
            .group(SettingGroup::new().title("Appearance").items(vec![...])),
        SettingPage::new("Software Update")
            .group(SettingGroup::new().title("Updates").items(vec![...])),
        SettingPage::new("About")
            .group(SettingGroup::new().items(vec![...])),
    ])

Group Variants

use gpui_component::group_box::GroupBoxVariant;

Settings::new("my-settings")
    .with_group_variant(GroupBoxVariant::Outline)
    .pages(vec![...])

Settings::new("my-settings")
    .with_group_variant(GroupBoxVariant::Fill)
    .pages(vec![...])

Setting Page

Basic Page

SettingPage::new("General")
    .group(SettingGroup::new().title("Options").items(vec![...]))

Multiple Groups

SettingPage::new("General")
    .groups(vec![
        SettingGroup::new().title("Appearance").items(vec![...]),
        SettingGroup::new().title("Font").items(vec![...]),
        SettingGroup::new().title("Other").items(vec![...]),
    ])

Icon

SettingPage::new("General")
    .icon(IconName::Settings)
    .groups(vec![...])

Default Open

SettingPage::new("General")
    .default_open(true)
    .groups(vec![...])

resettable

Enable reset functionality for a page:

SettingPage::new("General")
    .resettable(true)
    .groups(vec![...])

Setting Group

Basic Group

SettingGroup::new()
    .title("Appearance")
    .items(vec![
        SettingItem::new(...),
        SettingItem::new(...),
    ])

Single Item

SettingGroup::new()
    .title("Font")
    .item(SettingItem::new(...))

Without Title

SettingGroup::new()
    .items(vec![...])

Setting Item

Basic Item

SettingItem::new("Title", SettingField::switch(...))
    .description("Description text")

Custom Item with a render closure

You can create a fully custom setting item using SettingItem::render:

SettingItem::render(|options, _, _| {
    h_flex()
        .w_full()
        .justify_between()
        .child("Custom content")
        .child(
            Button::new("action")
                .label("Action")
                .with_size(options.size)
        )
        .into_any_element()
})

Vertical Layout

By default, setting items use horizontal layout. Use layout(Axis::Vertical) for vertical layout:

SettingItem::new(
    "CLI Path",
    SettingField::input(...)
)
.layout(Axis::Vertical)
.description("This item uses vertical layout.")

With Markdown Description

use gpui_component::text::markdown;

SettingItem::new(
    "Documentation",
    SettingField::element(...)
)
.description(markdown("Rust doc for the `gpui-component` crate."))

Setting Fields

The SettingField enum provides different field types for various input needs.

Switch

The switch field represents a boolean on/off state.

SettingItem::new(
    "Dark Mode",
    SettingField::switch(
        |cx: &App| cx.theme().mode.is_dark(),
        |val: bool, cx: &mut App| {
            // Handle value change
        },
    )
    .default_value(false)
)

Checkbox

Like the switch, but uses a checkbox UI.

SettingItem::new(
    "Auto Switch Theme",
    SettingField::checkbox(
        |cx: &App| AppSettings::global(cx).auto_switch_theme,
        |val: bool, cx: &mut App| {
            AppSettings::global_mut(cx).auto_switch_theme = val;
        },
    )
    .default_value(false)
)

Input

Display a single line text input.

SettingItem::new(
    "CLI Path",
    SettingField::input(
        |cx: &App| AppSettings::global(cx).cli_path.clone(),
        |val: SharedString, cx: &mut App| {
            AppSettings::global_mut(cx).cli_path = val;
        },
    )
    .default_value("/usr/local/bin/bash".into())
)
.layout(Axis::Vertical)
.description("Path to the CLI executable.")

Dropdown

A dropdown with a list of options.

SettingItem::new(
    "Font Family",
    SettingField::dropdown(
        vec![
            ("Arial".into(), "Arial".into()),
            ("Helvetica".into(), "Helvetica".into()),
            ("Times New Roman".into(), "Times New Roman".into()),
        ],
        |cx: &App| AppSettings::global(cx).font_family.clone(),
        |val: SharedString, cx: &mut App| {
            AppSettings::global_mut(cx).font_family = val;
        },
    )
    .default_value("Arial".into())
)

NumberInput

use gpui_component::setting::NumberFieldOptions;

SettingItem::new(
    "Font Size",
    SettingField::number_input(
        NumberFieldOptions {
            min: 8.0,
            max: 72.0,
            ..Default::default()
        },
        |cx: &App| AppSettings::global(cx).font_size,
        |val: f64, cx: &mut App| {
            AppSettings::global_mut(cx).font_size = val;
        },
    )
    .default_value(14.0)
)

Custom Field by Render Closure

The SettingField::render method allows you to create a custom field using a closure that returns an element.

SettingItem::new(
    "GitHub Repository",
    SettingField::render(|options, _window, _cx| {
        Button::new("open-url")
            .outline()
            .label("Repository...")
            .with_size(options.size)
            .on_click(|_, _window, cx| {
                cx.open_url("https://github.com/example/repo");
            })
    })
)

Custom Field Element

You may have a complex field that you want to reuse, you may want split the element into a separate struct to do the complex logic.

In this case, the SettingFieldElement trait can help you to create a custom field element.

use gpui_component::setting::{SettingFieldElement, RenderOptions};

struct OpenURLSettingField {
    label: SharedString,
    url: SharedString,
}

impl SettingFieldElement for OpenURLSettingField {
    type Element = Button;

    fn render_field(&self, options: &RenderOptions, _: &mut Window, _: &mut App) -> Self::Element {
        let url = self.url.clone();
        Button::new("open-url")
            .outline()
            .label(self.label.clone())
            .with_size(options.size)
            .on_click(move |_, _window, cx| {
                cx.open_url(url.as_str());
            })
    }
}

Then use it in the setting item:

SettingItem::new(
    "GitHub Repository",
    SettingField::element(OpenURLSettingField {
        label: "Repository...".into(),
        url: "https://github.com/longbridge/gpui-component".into(),
    })
)
