Menu Utilities library for Desktop Applications.

Platforms supported:

Windows
macOS
Linux (gtk Only)

Platform-specific notes:

On Windows, accelerators don't work unless the win32 message loop calls TranslateAcceleratorW. See Menu::init_for_hwnd for more details

Cargo Features

common-controls-v6: Use TaskDialogIndirect API from ComCtl32.dll v6 on Windows for showing the predefined About menu item dialog.
libxdo: Enables linking to libxdo on Linux which is used for the predfined Copy, Cut, Paste and SelectAll menu item.
serde: Enables de/serializing the dpi types.

Dependencies (Linux Only)

gtk is used for menus and libxdo is used to make the predfined Copy, Cut, Paste and SelectAll menu items work. Be sure to install following packages before building:

Arch Linux / Manjaro:

pacman -S gtk3 xdotool

Debian / Ubuntu:

sudo apt install libgtk-3-dev libxdo-dev

Example

Create the menu and add your items

let menu = Menu::new();
let menu_item2 = MenuItem::new("Menu item #2", false, None);
let submenu = Submenu::with_items("Submenu Outer", true,&[
  &MenuItem::new("Menu item #1", true, Some(Accelerator::new(Some(Modifiers::ALT), Code::KeyD))),
  &PredefinedMenuItem::separator(),
  &menu_item2,
  &MenuItem::new("Menu item #3", true, None),
  &PredefinedMenuItem::separator(),
  &Submenu::with_items("Submenu Inner", true,&[
    &MenuItem::new("Submenu item #1", true, None),
    &PredefinedMenuItem::separator(),
    &menu_item2,
  ])
]);

Then add your root menu to a Window on Windows and Linux or use it as your global app menu on macOS

// --snip--
#[cfg(target_os = "windows")]
menu.init_for_hwnd(window.hwnd() as isize);
#[cfg(target_os = "linux")]
menu.init_for_gtk_window(&gtk_window, Some(&vertical_gtk_box));
#[cfg(target_os = "macos")]
menu.init_for_nsapp();

Context menus (Popup menus)

You can also use a [Menu] or a [Submenu] show a context menu.

// --snip--
let position = muda::PhysicalPosition { x: 100., y: 120. };
#[cfg(target_os = "windows")]
menu.show_context_menu_for_hwnd(window.hwnd() as isize, Some(position.into()));
#[cfg(target_os = "linux")]
menu.show_context_menu_for_gtk_window(&gtk_window, Some(position.into()));
#[cfg(target_os = "macos")]
menu.show_context_menu_for_nsview(nsview, Some(position.into()));

Processing menu events

You can use MenuEvent::receiver to get a reference to the MenuEventReceiver which you can use to listen to events when a menu item is activated

if let Ok(event) = MenuEvent::receiver().try_recv() {
    match event.id {
        _ if event.id == save_item.id() => {
            println!("Save menu item activated");
        },
        _ => {}
    }
}
