How to use the ActivityIndicator component
ActivityIndicator displays an animation to indicate that an activity of indeterminate length is currently happening. The animation remains active while the activity indicator is added to the display list — unless its
enabled property is set to
⚠️ Beta Notice: This component is still quite new to Feathers UI. It was included in the latest release because it should be stable enough for production use. However, some APIs may go through minor changes in upcoming releases — based on feedback from developers like you. Learn more about Beta APIs.
var activity = new ActivityIndicator(); addChild(activity);
To customize the duration (in seconds) of the activity indicator's animation, set the
activity.duration = 1.0;
A small number of styles may be customized on an
ActivityIndicator component, including a skin.
var skin = new DotsActivitySkin(); skin.numDots = 8; skin.dotRadius = 3.0; skin.endDotRadius = null; skin.dotColor = 0x333333; skin.endDotColor = null; skin.dotAlpha = 1.0; skin.endDotAlpha = 0.0; var size = 1.1 * activitySkin.dotRadius * activitySkin.numDots; skin.width = size; skin.height = size; skin.activitySkin = activitySkin;
Any display object may be passed to the
activitySkin property. By default, the skin's
alpha value will repeatedly fade in and out. However, if a custom skin implements the
IIndeterminateSkin interface, it can control its own animation. For instance, the
DotsActivitySkin used in the example above rotates its content over time.
