System Tray

Native application system tray.

Setup

Configure the systemTray object on tauri.conf.json:

{
"tauri": {
"systemTray": {
"iconPath": "icons/icon.png",
"iconAsTemplate": true
}
}
}

The iconAsTemplate is a boolean value that determines whether the image represents a Template Image on macOS.

Linux Setup

On Linux, you need to install one of libayatana-appindicator or libappindicator3 packages. Tauri determines which package to use at runtime, with libayatana being the preferred one if both are installed.

By default, the Debian package (.deb file) will add a dependency on libayatana-appindicator3-1. To create a Debian package targetting libappindicator3, set the TAURI_TRAY environment variable to libappindicator3.

The AppImage bundle automatically embeds the installed tray library, and you can also use the TAURI_TRAY environment variable to manually select it.

정보

libappindicator3 is unmaintained and does not exist on some distros like debian11, but libayatana-appindicator does not exist on older releases.

Creating a system tray

To create a native system tray, import the SystemTray type:

use tauri::SystemTray;

Initialize a new tray instance:

let tray = SystemTray::new();

Configuring a system tray context menu

Optionally you can add a context menu that is visible when the tray icon is right-clicked. Import the SystemTrayMenu, SystemTrayMenuItem and CustomMenuItem types:

use tauri::{CustomMenuItem, SystemTrayMenu, SystemTrayMenuItem};

Create the SystemTrayMenu:

// here `"quit".to_string()` defines the menu item id, and the second parameter is the menu item label.
let quit = CustomMenuItem::new("quit".to_string(), "Quit");
let hide = CustomMenuItem::new("hide".to_string(), "Hide");
let tray_menu = SystemTrayMenu::new()
.add_item(quit)
.add_native_item(SystemTrayMenuItem::Separator)
.add_item(hide);

Add the tray menu to the SystemTray instance:

let tray = SystemTray::new().with_menu(tray_menu);

Configure the app system tray

The created SystemTray instance can be set using the system_tray API on the tauri::Builder struct:

use tauri::{CustomMenuItem, SystemTray, SystemTrayMenu};

fn main() {
let tray_menu = SystemTrayMenu::new(); // insert the menu items here
let system_tray = SystemTray::new()
.with_menu(tray_menu);
tauri::Builder::default()
.system_tray(system_tray)
.run(tauri::generate_context!())
.expect("error while running tauri application");
}

Listening to system tray events

Each CustomMenuItem triggers an event when clicked. Also, Tauri emits tray icon click events. Use the on_system_tray_event API to handle them:

use tauri::{CustomMenuItem, SystemTray, SystemTrayMenu, SystemTrayEvent};
use tauri::Manager;

fn main() {
let tray_menu = SystemTrayMenu::new(); // insert the menu items here
tauri::Builder::default()
.system_tray(SystemTray::new().with_menu(tray_menu))
.on_system_tray_event(|app, event| match event {
SystemTrayEvent::LeftClick {
position: _,
size: _,
..
} => {
println!("system tray received a left click");
}
SystemTrayEvent::RightClick {
position: _,
size: _,
..
} => {
println!("system tray received a right click");
}
SystemTrayEvent::DoubleClick {
position: _,
size: _,
..
} => {
println!("system tray received a double click");
}
SystemTrayEvent::MenuItemClick { id, .. } => {
match id.as_str() {
"quit" => {
std::process::exit(0);
}
"hide" => {
let window = app.get_window("main").unwrap();
window.hide().unwrap();
}
_ => {}
}
}
_ => {}
})
.run(tauri::generate_context!())
.expect("error while running tauri application");
}

Updating system tray

The AppHandle struct has a tray_handle method, which returns a handle to the system tray allowing updating tray icon and context menu items:

Updating context menu items

use tauri::{CustomMenuItem, SystemTray, SystemTrayMenu, SystemTrayEvent};
use tauri::Manager;

fn main() {
let tray_menu = SystemTrayMenu::new(); // insert the menu items here
tauri::Builder::default()
.system_tray(SystemTray::new().with_menu(tray_menu))
.on_system_tray_event(|app, event| match event {
SystemTrayEvent::MenuItemClick { id, .. } => {
// get a handle to the clicked menu item
// note that `tray_handle` can be called anywhere,
// just get an `AppHandle` instance with `app.handle()` on the setup hook
// and move it to another function or thread
let item_handle = app.tray_handle().get_item(&id);
match id.as_str() {
"hide" => {
let window = app.get_window("main").unwrap();
window.hide().unwrap();
// you can also `set_selected`, `set_enabled` and `set_native_image` (macOS only).
item_handle.set_title("Show").unwrap();
}
_ => {}
}
}
_ => {}
})
.run(tauri::generate_context!())
.expect("error while running tauri application");
}

Updating tray icon

Note that you need to add icon-ico or icon-png feature flag to the tauri dependency in your Cargo.toml to be able to use Icon::Raw

app.tray_handle().set_icon(tauri::Icon::Raw(include_bytes!("../path/to/myicon.ico").to_vec())).unwrap();

Keep the app running in the background after closing all windows

By default, tauri closes the application when the last window is closed. If your app should run in the background, you can call api.prevent_close() like so:

tauri::Builder::default()
.build(tauri::generate_context!())
.expect("error while building tauri application")
.run(|_app_handle, event| match event {
tauri::RunEvent::ExitRequested { api, .. } => {
api.prevent_exit();
}
_ => {}
});
