//! 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.
//!
//! ```no_run,ignore
//! 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.
//!
//! ```no_run,ignore
//! let text = widget::text::body(&self.cached_text);
//! ```
//!
//! Use the [`cosmic::Apply`](crate::Apply) trait to embed widgets into other widgets which accept them.
//!
//! ```no_run,ignore
//! let button = widget::icon::from_name("printer-symbolic")
//!     .apply(widget::button::icon)
//!     .on_press(Message::Print);
//! ```
