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:
+ +// in your initialization function
+init : function(){
+ Ext.state.Manager.setProvider(new Ext.state.CookieProvider());
+ var win = new Window(...);
+ win.restoreState();
+}
+ This class passes on calls from components to the underlying 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.
