Class AnimationManager

java.lang.Object

com.codename1.ui.AnimationManager

public final class AnimationManager
extends Object

Animation manager concentrates all of the animations for a given form into a single place that allows us to manage all mutations to a Form in a way the prevents collisions between mutations. The one type of animation that isn't handled by this class is the form level transition, replace transitions are handled by this class.

Method Details

isAnimating

public boolean isAnimating()

Returns true if an animation is currently in progress

Returns

true if an animation is currently in progress

addUIMutation

public void addUIMutation(Container container,
 ComponentAnimation an)

Adds a UIMutation to the animation manager. If there are any current compatible UIMutations in the animation queue, then this mutation will be added to that mutation. Otherwise it will appended to the end of the queue to be run sequentially.

Parameters

• container: The container that is being mutated.

• an: The animation

onTitleScrollAnimation

public void onTitleScrollAnimation(Container content,
 ComponentAnimation... cna)

flushAnimation

public void flushAnimation(Runnable r)

Invokes the runnable when all animations have completed

Parameters

• r: the runnable that will be invoked after the animations
