Module cosmic::widget

The COSMIC widget library

This module contains a wide variety of widgets used throughout the COSMIC app ecosystem.

Overview

Add widgets to your application view by calling the modules and functions below. Widgets are constructed by chaining their property methods using a functional paradigm. Modules may contain additional functions for constructing different variations of a widget. Each module will typically have one widget with the same name as the module, which will be re-exported here.

use cosmic::prelude::*;
use cosmic::{cosmic_theme, theme, widget};

const REPOSITORY: &str = "https://github.com/pop-os/libcosmic";

let cosmic_theme::Spacing { space_xxs, .. } = theme::active().cosmic().spacing;

let link = widget::button::link(REPOSITORY)
    .on_press(Message::LaunchUrl(REPOSITORY))
    .padding(0);

let content = widget::column()
    .push(widget::icon::from_name("my-app-icon"))
    .push(widget::text::title3("My App Name"))
    .push(link)
    .align_items(Alignment::Center)
    .spacing(space_xxs);

Widgets may borrow data from your application struct, and should do so to avoid allocating.

let text = widget::text::body(&self.cached_text);

Use the cosmic::Apply trait to embed widgets into other widgets which accept them.

let button = widget::icon::from_name("printer-symbolic")
    .apply(widget::button::icon)
    .on_press(Message::Print);
