Detailed Description

The Kanzi animation system consists of animations, which define how to animate properties, and timelines, which map animations to time and to the objects that you want to animate.

Property timeline applies an animation to a property of an object. For example, to change the layout size of an Image2D node, use the property timeline to animate the Node::WidthProperty and Node::HeightProperty properties of that node.

Examples

To create a property timeline:

        // Create a property timeline and apply the linearAnimation animation to the Layout Width property
        // to animate the width of the current node.
        PropertyAnimationTimelineSharedPtr propertyTimeline = PropertyAnimationTimeline::create(domain, ".", Node::WidthProperty, linearAnimation);

To play an animation regardless of the timeline type:

        // Create the playback context and the timeline playback for the node defined in the item2d.
        SceneGraphTimelinePlaybackContext context(*item2d);
        // Create the playback for the timeline defined in the propertyFieldTimeline.
        TimelinePlaybackSharedPtr playback = propertyFieldTimeline->createPlayback(context);
        // Start the animation.
        domain->getRootTimelineClock()->addTimelinePlayback(playback);
