9 | * This is the global state manager. By default all components that are "state aware" check this class |
---|
10 | * for state information if you don't pass them a custom state provider. In order for this class |
---|
11 | * to be useful, it must be initialized with a provider when your application initializes. Example usage: |
---|
12 | <pre><code> |
---|
13 | // in your initialization function |
---|
14 | init : function(){ |
---|
15 | Ext.state.Manager.setProvider(new Ext.state.CookieProvider()); |
---|
16 | var win = new Window(...); |
---|
17 | win.restoreState(); |
---|
18 | } |
