Class IlvCardLayout

java.lang.Object
  ilog.views.graphic.composite.layout.IlvCardLayout

All Implemented Interfaces:

IlvLayoutManager, IlvPersistentObject, Cloneable

public class IlvCardLayout
extends Object
implements IlvLayoutManager

This class treats each IlvAttachable object within a container as a card. Only one card is visible at a time, and the container acts as a stack of cards. The first component added to a CardLayout object is the visible component when the container is first displayed.

Since:

JViews 6.0
