Class DelegatingLayoutManager

java.lang.Object
  com.partnersoft.gui.DelegatingLayoutManager

All Implemented Interfaces:

java.awt.LayoutManager, java.awt.LayoutManager2

Direct Known Subclasses:

FormLayout

public class DelegatingLayoutManager
extends java.lang.Object
implements java.awt.LayoutManager2

This is a starting point for delegation-based layout managers. By default, it refers all methods to the provided delegate. You can then override it however you like to achieve custom behavior. It's probably not very useful by itself, however it is not declared abstract.
