- * @class Ext.Component
- * @extends Ext.util.Observable
- * <p>Base class for all Ext components. All subclasses of Component may participate in the automated
- * Ext component lifecycle of creation, rendering and destruction which is provided by the {@link Ext.Container Container} class.
- * Components may be added to a Container through the {@link Ext.Container#items items} config option at the time the Container is created,
- * or they may be added dynamically via the {@link Ext.Container#add add} method.</p>
- * <p>The Component base class has built-in support for basic hide/show and enable/disable behavior.</p>
- * <p>All Components are registered with the {@link Ext.ComponentMgr} on construction so that they can be referenced at any time via
- * {@link Ext#getCmp}, passing the {@link #id}.</p>
- * <p>All user-developed visual widgets that are required to participate in automated lifecycle and size management should subclass Component (or
- * {@link Ext.BoxComponent} if managed box model handling is required, ie height and width management).</p>
- * <p>See the <a href="http://extjs.com/learn/Tutorial:Creating_new_UI_controls">Creating new UI controls</a> tutorial for details on how
- * and to either extend or augment ExtJs base classes to create custom Components.</p>
- * <p>Every component has a specific xtype, which is its Ext-specific type name, along with methods for checking the
- * xtype like {@link #getXType} and {@link #isXType}. This is the list of all valid xtypes:</p>

- /**
- * @cfg {Boolean} stateful
- * <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>{@link #stateId}</code> or <code>{@link #id}</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 {@link Ext.state.Provider} which overrides the
- * {@link Ext.state.Provider#set set} and {@link Ext.state.Provider#get get}
- * methods to save and recall name/value pairs. A built-in implementation,
- * {@link Ext.state.CookieProvider} is available.</p>
- * <p>To set the state provider for the current page:</p>
- * <pre><code>
-Ext.state.Manager.setProvider(new Ext.state.CookieProvider({
- expires: new Date(new Date().getTime()+(1000*60*60*24*7)), //7 days from now
-}));
- * </code></pre>
- * <p>A stateful Component attempts to save state when one of the events
- * listed in the <code>{@link #stateEvents}</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 {@link Ext.state.Manager#set}
- * which uses the configured {@link Ext.state.Provider} to save the object
- * keyed by the Component's <code>{@link stateId}</code>, or, if that is not
- * specified, its <code>{@link #id}</code>.</p>
- * <p>During construction, a stateful Component attempts to <i>restore</i>
- * its state by calling {@link Ext.state.Manager#get} passing the
- * <code>{@link #stateId}</code>, or, if that is not specified, the
- * <code>{@link #id}</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 {@link #beforestaterestore}, {@link #staterestore},
- * {@link #beforestatesave} and {@link #statesave} events.</p>
