<p>The ancestor axis can be traversed by using '/' characters in the path.
For example, to put a reference to a Toolbar Button into <i>the Panel which owns the Toolbar</i>:</p><pre><code><b>var</b> myGrid = <b>new</b> Ext.grid.EditorGridPanel({

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>,

<b>Combining Options</b><br>
Using the options argument, it is possible to combine different types of listeners:<br>
<br>
A delayed, one-time listener.
<pre><code>myDataView.on(<em>'click'</em>, this.onClick, this, {
    single: true,
    delay: 100
});</code></pre>
<p>
<b>Attaching multiple handlers in 1 call</b><br>
The method also allows for a single argument to be passed which is a config object containing properties
which specify multiple handlers.
<p>
<pre><code>myGridPanel.on({
    <em>'click'</em> : {
        fn: this.onClick,
        scope: this,
        delay: 100
    },
    <em>'mouseover'</em> : {
        fn: this.onMouseOver,
        scope: this
    },
    <em>'mouseout'</em> : {
        fn: this.onMouseOut,
        scope: this
    }
});</code></pre>
<p>
Or a shorthand syntax:<br>
<pre><code>myGridPanel.on({

<p>Certain layout managers allow dynamic addition of child components. Those that do
