Module: Toybox.WatchUi

Overview

The WatchUi module contains user interface elements available within apps.

WatchUi provides several classes that represent Views, or what is displayed on the screen of a device. Also available are UI elements like on-screen menus, progress bars, buttons, and various pickers. More abstract classes represent all drawable objects, such as bitmaps and text.

Note:

All keys in the key types enum listed after EXTENDED_KEYS (16) were added after ConnectIQ version 1.1.2. Before evaluating these keys, check for the availability of these keys with a has check: if (Toybox.WatchUi has :EXTENDED_KEYS) ...

Instance Method Details

animate(object as Lang.Object, property as Lang.Symbol, type as WatchUi.AnimationType, start as Lang.Numeric, stop as Lang.Numeric, period as Lang.Numeric, callback as Null or Lang.Method() as Void) as Void

Animate an Object.

Animate works by changing an object property over time, such as the x-position of a Drawable. The animation starts after the call and runs the length of the specified period. During this time, the View object's onUpdate() method will be invoked at an increased rate to facilitate animation.

Note:

Will cause an app crash if called from background or data field app, or from watch face while in low power mode

Parameters:

Example:

Move a bitmap across the screen from left to right

using System.WatchUi;

square = new Ui.Bitmap({
    :rezId=>Rez.Drawables.square,
    :locX=>10,
    :locY=>30
});
WatchUi.animate(square, :locX, Ui.ANIM_TYPE_LINEAR, 10, 200, 10, null);
