Class WindowFollowBehavior

java.lang.Object

java.awt.event.ComponentAdapter

com.alee.utils.swing.WindowFollowBehavior

All Implemented Interfaces:

Behavior, java.awt.event.ComponentListener, java.util.EventListener

public class WindowFollowBehavior
extends java.awt.event.ComponentAdapter
implements Behavior

This behavior allows you to quickly attach one window to another window. Window will always follow the other one it is attached by moving for the same distance window it is attached to was moved. But window this one is attached to will not follow this window as it moves.

It is not recommended to use this behavior to completely lock two windows to each other as it will cause issues. Another behavior will be available later-on to provide that kind of functionality.
