Crate tray_icon

Source
Expand description

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.

§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:
pacman -S gtk3 xdotool libappindicator-gtk3 #or libayatana-appindicator
§Debian / Ubuntu:
sudo apt install libgtk-3-dev libxdo-dev libappindicator3-dev #or libayatana-appindicator3-dev

§Examples

§Create a tray icon without a menu.
use tray_icon::{TrayIconBuilder, Icon};

let tray_icon = TrayIconBuilder::new()
    .with_tooltip("system-tray - tray icon library!")
    .with_icon(icon)
    .build()
    .unwrap();
§Create a tray icon with a menu.
use tray_icon::{TrayIconBuilder, menu::Menu,Icon};

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

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 to get events for the tray context menu.

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);
}
