internal properties from a saved state on startu...</div><div class="long"><p>A flag which causes the Component to attempt to restore the state of
internal properties from a saved state on startup. The component must have
either a <code><a href="output/Ext.Component.html#Ext.Component-stateId" ext:member="stateId" ext:cls="Ext.Component">stateId</a></code> or <code><a href="output/Ext.Component.html#Ext.Component-id" ext:member="id" ext:cls="Ext.Component">id</a></code> assigned
for state to be managed. Auto-generated ids are not guaranteed to be stable
across page loads and cannot be relied upon to save and restore the same
state for a component.<p>
<p>For state saving to work, the state manager's provider must have been
set to an implementation of <a href="output/Ext.state.Provider.html" ext:cls="Ext.state.Provider">Ext.state.Provider</a> which overrides the
<a href="output/Ext.state.Provider.html#Ext.state.Provider-set" ext:member="set" ext:cls="Ext.state.Provider">set</a> and <a href="output/Ext.state.Provider.html#Ext.state.Provider-get" ext:member="get" ext:cls="Ext.state.Provider">get</a>
methods to save and recall name/value pairs. A built-in implementation,
<a href="output/Ext.state.CookieProvider.html" ext:cls="Ext.state.CookieProvider">Ext.state.CookieProvider</a> is available.</p>
<p>To set the state provider for the current page:</p>
<pre><code>Ext.state.Manager.setProvider(<b>new</b> Ext.state.CookieProvider({
    expires: <b>new</b> Date(<b>new</b> Date().getTime()+(1000*60*60*24*7)), <i>//7 days from now</i>
}));</code></pre>
<p>A stateful Component attempts to save state when one of the events
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>
<p>To save state, a stateful Component first serializes its state by
calling <b><code>getState</code></b>. By default, this function does
nothing. The developer must provide an implementation which returns an
object hash which represents the Component's restorable state.</p>
<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>
which uses the configured <a href="output/Ext.state.Provider.html" ext:cls="Ext.state.Provider">Ext.state.Provider</a> to save the object
keyed by the Component's <code><a href="output/stateId.html" ext:cls="stateId">stateId</a></code>, or, if that is not
specified, its <code><a href="output/Ext.Component.html#Ext.Component-id" ext:member="id" ext:cls="Ext.Component">id</a></code>.</p>
<p>During construction, a stateful Component attempts to <i>restore</i>
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
<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
<code><a href="output/Ext.Component.html#Ext.Component-id" ext:member="id" ext:cls="Ext.Component">id</a></code>.</p>
<p>The resulting object is passed to <b><code>applyState</code></b>.
The default implementation of <code>applyState</code> simply copies
properties into the object, but a developer may override this to support
more behaviour.</p>
<p>You can perform extra processing on state save and restore by attaching
handlers to the <a href="output/Ext.Component.html#Ext.Component-beforestaterestore" ext:member="beforestaterestore" ext:cls="Ext.Component">beforestaterestore</a>, <a href="output/Ext.Component.html#Ext.Component-staterestore" ext:member="staterestore" ext:cls="Ext.Component">staterestore</a>,

<a href="output/Ext.Container.html#Ext.Container-layout" ext:member="layout" ext:cls="Ext.Container">layout</a> manager when the Container is first rendered.</p>
<p>Certain layout managers allow dynamic addition of child components. Those that do

the Container's <a href="output/Ext.Container.html#Ext.Container-doLayout" ext:member="doLayout" ext:cls="Ext.Container">doLayout</a> to refresh the view which causes any
unrendered child Components to be rendered. This is required so that you can add multiple
child components if needed while only refreshing the layout once.</p>
<p>When creating complex UIs, it is important to remember that sizing and positioning
of child items is the responsibility of the Container's <a href="output/Ext.Container.html#Ext.Container-layout" ext:member="layout" ext:cls="Ext.Container">layout</a> manager.
If you expect child items to be sized in response to user interactions, you must
configure the Container with a layout manager which creates and manages the type of layout you
have in mind.</p>
<p><b>Omitting the Container's <a href="output/Ext.Container.html#Ext.Container-layout" ext:member="layout" ext:cls="Ext.Container">layout</a> config means that a basic
