    /**
     * @class Ext.Component
     * @extends Ext.AbstractComponent
     * <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 Container} class.
     * Components may be added to a Container through the {@link Ext.container.Container#items items} config option at the time the Container is created,
     * or they may be added dynamically via the {@link Ext.container.Container#add add} method.</p>
     * <p>The Component base class has built-in support for basic hide/show and enable/disable and size control behavior.</p>
     * <p>All Components are registered with the {@link Ext.ComponentManager} on construction so that they can be referenced at any time via
     * {@link Ext#getCmp 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.</p>
     * <p>See the <a href="http://sencha.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>

     * It should not usually be necessary to instantiate a Component because there are provided subclasses which implement specialized Component
     * use cases which over most application needs. However it is possible to instantiate a base Component, and it will be renderable,
     * or will particpate in layouts as the child item of a Container:
    {@img Ext.Component/Ext.Component.png Ext.Component component}
