muda/README.md

muda is a Menu Utilities library for Desktop Applications.

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 Only 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);
#[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 x = 100;
let y = 120;
#[cfg(target_os = "windows")]
menu.show_context_menu_for_hwnd(window.hwnd() as isize, x, y);
#[cfg(target_os = "linux")]
menu.show_context_menu_for_gtk_window(&gtk_window, x, y);
#[cfg(target_os = "macos")]
menu.show_context_menu_for_nsview(nsview, x, y);

Processing menu events

You can use menu_event_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) = menu_event_receiver().try_recv() {
    match event.id {
        _ if event.id == save_item.id() => {
            println!("Save menu item activated");
        },
        _ => {}
    }
}

Platform-specific notes:

Accelerators on Windows

Accelerators don't work unless the win32 message loop calls TranslateAcceleratorW

See Menu::init_for_hwnd for more details

Linux

libx 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 xdotool

Debian / Ubuntu:

sudo apt install libxdo-dev
