360 across page loads and cannot be relied upon to save and restore the same
361 state for a component.<p>
362 <p>For state saving to work, the state manager's provider must have been
363 set to an implementation of <a href="output/Ext.state.Provider.html" ext:cls="Ext.state.Provider">Ext.state.Provider</a> which overrides the

365 methods to save and recall name/value pairs. A built-in implementation,
366 <a href="output/Ext.state.CookieProvider.html" ext:cls="Ext.state.CookieProvider">Ext.state.CookieProvider</a> is available.</p>
367 <p>To set the state provider for the current page:</p>
368 <pre><code>Ext.state.Manager.setProvider(<b>new</b> Ext.state.CookieProvider({
369 expires: <b>new</b> Date(<b>new</b> Date().getTime()+(1000*60*60*24*7)), <i>//7 days from now</i>
371 <p>A stateful Component attempts to save state when one of the events
372 listed in the <code><a href="output/Ext.Component.html#Ext.Component-stateEvents" ext:member="stateEvents" ext:cls="Ext.Component">stateEvents</a></code> configuration fires.</p>
373 <p>To save state, a stateful Component first serializes its state by
374 calling <b><code>getState</code></b>. By default, this function does
375 nothing. The developer must provide an implementation which returns an
376 object hash which represents the Component's restorable state.</p>
377 <p>The value yielded by getState is passed to <a href="output/Ext.state.Manager.html#Ext.state.Manager-set" ext:member="set" ext:cls="Ext.state.Manager">Ext.state.Manager.set</a>
378 which uses the configured <a href="output/Ext.state.Provider.html" ext:cls="Ext.state.Provider">Ext.state.Provider</a> to save the object
379 keyed by the Component's <code><a href="output/stateId.html" ext:cls="stateId">stateId</a></code>, or, if that is not
380 specified, its <code><a href="output/Ext.Component.html#Ext.Component-id" ext:member="id" ext:cls="Ext.Component">id</a></code>.</p>
381 <p>During construction, a stateful Component attempts to <i>restore</i>
382 its state by calling <a href="output/Ext.state.Manager.html#Ext.state.Manager-get" ext:member="get" ext:cls="Ext.state.Manager">Ext.state.Manager.get</a> passing the
383 <code><a href="output/Ext.Component.html#Ext.Component-stateId" ext:member="stateId" ext:cls="Ext.Component">stateId</a></code>, or, if that is not specified, the
384 <code><a href="output/Ext.Component.html#Ext.Component-id" ext:member="id" ext:cls="Ext.Component">id</a></code>.</p>
385 <p>The resulting object is passed to <b><code>applyState</code></b>.
386 The default implementation of <code>applyState</code> simply copies
387 properties into the object, but a developer may override this to support
