//! tray-icon lets you create tray icons for desktop applications.
//!
//! # Platforms supported:
//!
//! - Windows
//! - macOS
//! - Linux (gtk Only)
//!
//! # Platform-specific notes:
//!
//! - On Windows and Linux, an event loop must be running on the thread, on Windows, a win32 event loop and on Linux, a gtk event loop. It doesn't need to be the main thread but you have to create the tray icon on the same thread as the event loop.
//! - On macOS, an event loop must be running on the main thread so you also need to create the tray icon on the main thread. You must make sure that the event loop is already running and not just created before creating a TrayIcon to prevent issues with fullscreen apps. In Winit for example the earliest you can create icons is on [`StartCause::Init`](https://docs.rs/winit/latest/winit/event/enum.StartCause.html#variant.Init).
//!
//! # Dependencies (Linux Only)
//!
//! On Linux, `gtk`, `libxdo` is used to make the predfined `Copy`, `Cut`, `Paste` and `SelectAll` menu items work and `libappindicator` or `libayatnat-appindicator` are used to create the tray icon, so make sure to install them on your system.
//!
//! #### Arch Linux / Manjaro:
//!
//! ```sh
//! pacman -S gtk3 xdotool libappindicator-gtk3 #or libayatana-appindicator
//! ```
//!
//! #### Debian / Ubuntu:
//!
//! ```sh
//! sudo apt install libgtk-3-dev libxdo-dev libappindicator3-dev #or libayatana-appindicator3-dev
//! ```
//!
//! # Examples
//!
//! #### Create a tray icon without a menu.
//!
//! ```no_run
//! use tray_icon::{TrayIconBuilder, Icon};
//!
//! # let icon = Icon::from_rgba(Vec::new(), 0, 0).unwrap();
//! let tray_icon = TrayIconBuilder::new()
//!     .with_tooltip("system-tray - tray icon library!")
//!     .with_icon(icon)
//!     .build()
//!     .unwrap();
//! ```
//!
//! #### Create a tray icon with a menu.
//!
//! ```no_run
//! use tray_icon::{TrayIconBuilder, menu::Menu,Icon};
//!
//! # let icon = Icon::from_rgba(Vec::new(), 0, 0).unwrap();
//! let tray_menu = Menu::new();
//! let tray_icon = TrayIconBuilder::new()
//!     .with_menu(Box::new(tray_menu))
//!     .with_tooltip("system-tray - tray icon library!")
//!     .with_icon(icon)
//!     .build()
//!     .unwrap();
//! ```
//!
//! # Processing tray events
//!
//! You can use [`TrayIconEvent::receiver`] to get a reference to the [`TrayIconEventReceiver`]
//! which you can use to listen to events when a click happens on the tray icon
//! ```no_run
//! use tray_icon::TrayIconEvent;
//!
//! if let Ok(event) = TrayIconEvent::receiver().try_recv() {
//!     println!("{:?}", event);
//! }
//! ```
//!
//! You can also listen for the menu events using [`MenuEvent::receiver`](crate::menu::MenuEvent::receiver) to get events for the tray context menu.
//!
//! ```no_run
//! use tray_icon::{TrayIconEvent, menu::MenuEvent};
//!
//! if let Ok(event) = TrayIconEvent::receiver().try_recv() {
//!     println!("tray event: {:?}", event);
//! }
//!
//! if let Ok(event) = MenuEvent::receiver().try_recv() {
//!     println!("menu event: {:?}", event);
//! }
//! ```
//!
//! ### Note for [winit] or [tao] users:
//!
//! You should use [`TrayIconEvent::set_event_handler`] and forward
//! the tray icon events to the event loop by using [`EventLoopProxy`]
//! so that the event loop is awakened on each tray icon event.
//! Same can be done for menu events using [`MenuEvent::set_event_handler`].
//!
//! ```no_run
//! # use winit::event_loop::EventLoop;
//! enum UserEvent {
//!   TrayIconEvent(tray_icon::TrayIconEvent),
//!   MenuEvent(tray_icon::menu::MenuEvent)
//! }
//!
//! let event_loop = EventLoop::<UserEvent>::with_user_event().build().unwrap();
//!
//! let proxy = event_loop.create_proxy();
//! tray_icon::TrayIconEvent::set_event_handler(Some(move |event| {
//!     proxy.send_event(UserEvent::TrayIconEvent(event));
//! }));
//!
//! let proxy = event_loop.create_proxy();
//! tray_icon::menu::MenuEvent::set_event_handler(Some(move |event| {
//!     proxy.send_event(UserEvent::MenuEvent(event));
//! }));
//! ```
