API

Menu()

Create a new Menu:

var Menu = require('menu');
var menu = new Menu();
var menu = Menu();

Menu#add(slug, text, fn)

Add a new menu item with the given text, optional slug and callback fn.

Using events to handle selection:

menu.add('Hello');

menu.on('Hello', function(){
  console.log('clicked hello');
});

Using callbacks:

menu.add('Hello', function(){
  console.log('clicked hello');
});

Using a custom slug, otherwise "hello" is generated from the text given, which may conflict with "rich" styling like icons within menu items, or i18n.

menu.add('add-item', 'Add Item');

menu.on('add-item', function(){
  console.log('clicked "Add Item"');
});

menu.add('add-item', 'Add Item', function(){
  console.log('clicked "Add Item"');
});

Menu#remove(slug)

Remove an item by the given slug:

menu.add('Add item');
menu.remove('Add item');

Or with custom slugs:

menu.add('add-item', 'Add item');
menu.remove('add-item');

Menu#has(slug)

Check if a menu item is present.

menu.add('Add item');

menu.has('Add item');
// => true

menu.has('add-item');
// => true

menu.has('Foo');
// => false

Menu#moveTo(x, y)

Move the menu to (x, y).

Menu#show()

Show the menu.

Menu#hide()

Hide the menu.
