Class: Toybox.WatchUi.Menu2

Inherits:
Toybox.WatchUi.View show all

Overview

A representation of an on-screen menu. A Menu2 is a special View, similar to a Toybox::WatchUi::Menu, that presents the user with a list of options. A Menu2 offers more capabilities than a Toybox::WatchUi::Menu, like graphical titles, menu items that can be updated dynamically, and additional menu elements such as check boxes.

After an option is selected, the registered onSelect() method will be called. While a Menu2 can be generated programmatically, they should generally be created as a resource.

A Menu2 is pushed using pushView(), which provides a Menu2InputDelegate as the input delegate.

Note:

The look and feel of a Menu2 is device-specific.

Example:

Build a simple Menu2 programmatically

using Toybox.WatchUi;

class MyBehaviorDelegate extends WatchUi.BehaviorDelegate {
    function initialize() {
        BehaviorDelegate.initialize();
    }

    function onMenu() {
        var menu = new WatchUi.Menu2({:title=>"My Menu2"});
        var delegate;
        menu.addItem(
            new MenuItem(
                "Item 1 Label",
                "Item 1 subLabel",
                "itemOneId",
                {}
            )
        );
        menu.addItem(
            new MenuItem(
                "Item 2 Label",
                "Item 2 subLabel",
                "itemTwoId",
                {}
            )
        );
        delegate = new MyMenu2Delegate(); // a WatchUi.Menu2InputDelegate
        WatchUi.pushView(menu, delegate, WatchUi.SLIDE_IMMEDIATE);
        return true;
    }
}
