Menu bar

Prefer menu bar over drop menu? Chorus' API supports that too.
createMenuBarButton(name, id) will create a button on the menu bar and return its instance. Note that id is optional and, if not specified, will take the value of name.

function onInit() {
    const menu = createMenuBarButton('Hello', 'hello');
}

However, there are no sub-buttons. They can be added by calling its addButton(text, action, combination) function, where combination is optional.

function onInit() {
    const menu = createMenuBarButton('Hello', 'hello');
    menu.addButton('World', () => {
        alert('Hello, world!');
    })
}

If you want to get the instance of an existing button call getMenuBarButton(id) (built-in IDs are file, edit, addons and help).

We can also set an accelerator (key combination) for the button by instantiating a KeyCombination (see here).

Final example:

function onInit() {
    const menu = createMenuBarButton('Hello', 'hello');
    menu.addButton('World', () => alert('Hello, world!'), new KeyCombination('J', ['control', 'shift']));
}
