Class ListAnimator

java.lang.Object

furbelow.AbstractComponentDecorator

furbelow.ListAnimator

public abstract class ListAnimator
extends AbstractComponentDecorator

Animates moving list cells out of the way for a potential drop. This decorator completely over-paints the target JList, optionally painting a dragged item and animating creation of a space for the dragged item to be dropped.

Description copied from class: AbstractComponentDecorator
