- * 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. Example usage:
- <pre><code>
-// in your initialization function
-init : function(){
- Ext.state.Manager.setProvider(new Ext.state.CookieProvider());
- var win = new Window(...);
- win.restoreState();
-}
- </code></pre>
- * This class passes on calls from components to the underlying {@link Ext.state.Provider} so that
- * there is a common interface that can be used without needing to refer to a specific provider instance
- * in every component.
