Window Menu

Native application menus can be attached to a window.

Creating a menu

To create a native window menu, import the Menu, Submenu, MenuItem and CustomMenuItem types. The MenuItem enum contains a collection of platform-specific items (currently not implemented on Windows). The CustomMenuItem allows you to create your own menu items and add special functionality to them.

use tauri::{CustomMenuItem, Menu, MenuItem, Submenu};

Create a Menu instance:

// 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 close = CustomMenuItem::new("close".to_string(), "Close");
let submenu = Submenu::new("File", Menu::new().add_item(quit).add_item(close));
let menu = Menu::new()
  .add_native_item(MenuItem::Copy)
  .add_item(CustomMenuItem::new("hide", "Hide"))
  .add_submenu(submenu);

Adding the menu to all windows

The defined menu can be set to all windows using the menu API on the tauri::Builder struct:

use tauri::{CustomMenuItem, Menu, MenuItem, Submenu};

fn main() {
  let menu = Menu::new(); // configure the menu
  tauri::Builder::default()
    .menu(menu)
    .run(tauri::generate_context!())
    .expect("error while running tauri application");
}

Adding the menu to a specific window

You can create a window and set the menu to be used. This allows defining a specific menu set for each application window.

use tauri::{CustomMenuItem, Menu, MenuItem, Submenu};
use tauri::WindowBuilder;

fn main() {
  let menu = Menu::new(); // configure the menu
  tauri::Builder::default()
    .create_window(
      "main-window".to_string(),
      tauri::WindowUrl::App("index.html".into()),
      move |window_builder, webview_attributes| {
        (window_builder.menu(menu), webview_attributes)
      },
    )
    .run(tauri::generate_context!())
    .expect("error while running tauri application");
}

Listening to events on custom menu items

Each CustomMenuItem triggers an event when clicked. Use the on_menu_event API to handle them, either on the global tauri::Builder or on an specific window.

Listening to events on global menus

use tauri::{CustomMenuItem, Menu, MenuItem};

fn main() {
  let menu = vec![]; // insert the menu array here
  tauri::Builder::default()
    .menu(menu)
    .on_menu_event(|event| {
      match event.menu_item_id() {
        "quit" => {
          std::process::exit(0);
        }
        "close" => {
          event.window().close().unwrap();
        }
        _ => {}
      }
    })
    .run(tauri::generate_context!())
    .expect("error while running tauri application");
}

Listening to events on window menus

use tauri::{CustomMenuItem, Menu, MenuItem};
use tauri::{Manager, WindowBuilder};

fn main() {
  let menu = vec![]; // insert the menu array here
  tauri::Builder::default()
    .create_window(
      "main-window".to_string(),
      tauri::WindowUrl::App("index.html".into()),
      move |window_builder, webview_attributes| {
        (window_builder.menu(menu), webview_attributes)
      },
    )
    .setup(|app| {
      let window = app.get_window("main-window").unwrap();
      let window_ = window.clone();
      window.on_menu_event(move |event| {
        match event.menu_item_id().as_str() {
          "quit" => {
            std::process::exit(0);
          }
          "close" => {
            window_.close().unwrap();
          }
          _ => {}
        }
      });
      Ok(())
    })
    .run(tauri::generate_context!())
    .expect("error while running tauri application");
}

Updating menu items

The Window struct has a menu_handle method, which allows updating menu items:

fn main() {
  tauri::Builder::default()
    .setup(|app| {
      let main_window = app.get_window("main").unwrap();
      let menu_handle = main_window.menu_handle();
      std::thread::spawn(move || {
        // you can also `set_selected`, `set_enabled` and `set_native_image` (macOS only).
        menu_handle.get_item("item_id").set_title("New title");
      })
      Ok(())
    })
}
