Class Ext.state.Manager

Package:	Ext.state
Class:	Manager
Extends:	Object
Defined In:	State.js

This is the global state manager. By default all components that are "state aware" check this class for state information if you don't pass them a custom state provider. In order for this class to be useful, it must be initialized with a provider when your application initializes.

// in your initialization function
init : function(){
   Ext.state.Manager.setProvider(new Ext.state.CookieProvider());
   ...
   // supposed you have a Ext.BorderLayout
   var layout = new Ext.BorderLayout(...);
   layout.restoreState();
   // or a {Ext.BasicDialog}
   var dialog = new Ext.BasicDialog(...);
   dialog.restoreState();

This class is a singleton and cannot be created directly.
