See the [Component Guide][1] for more information on xtypes and the * Component hierarchy. * * ## Finding components * * 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}. * * Additionally the {@link Ext.ComponentQuery} provides a CSS-selectors-like way to look up components by their xtype * and many other attributes.  For example the following code will find all textfield components inside component with * `id: 'myform'`: * *     Ext.ComponentQuery.query('#myform textfield'); * * ## Extending Ext.Component * * 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#cfg-items items} config option * at the time the Container is created, or they may be added dynamically via the * {@link Ext.container.Container#method-add add} method. * * All user-developed visual widgets that are required to participate in automated lifecycle and size management should * subclass Component. * * See the Creating new UI controls chapter in [Component Guide][1] for details on how and to either extend * or augment Ext JS base classes to create custom Components. * * ## The Ext.Component class by itself * * Usually one doesn't need to instantiate the Ext.Component class. There are subclasses which implement * specialized use cases, covering most application needs. However it is possible to instantiate a base * Component, and it can be rendered to document, or handled by layouts as the child item of a Container: * *     @example *     Ext.create('Ext.Component', { *         html: 'Hello world!', *         width: 300, *         height: 200, *         padding: 20, *         style: { *             color: '#FFFFFF', *             backgroundColor:'#000000' *         }, *         renderTo: Ext.getBody() *     }); * * The Component above creates its encapsulating `div` upon render, and use the configured HTML as content. More complex * internal structure may be created using the {@link #renderTpl} configuration, although to display database-derived * mass data, it is recommended that an ExtJS data-backed Component such as a {@link Ext.view.View View}, * {@link Ext.grid.Panel GridPanel}, or {@link Ext.tree.Panel TreePanel} be used. * * [1]: #!/guide/components */Ext.define('Ext.Component', {    /* Begin Definitions */    alias: ['widget.component', 'widget.box'],    extend: 'Ext.AbstractComponent',    requires: [        'Ext.util.DelayedTask'    ],    uses: [        'Ext.Layer',        'Ext.resizer.Resizer',        'Ext.util.ComponentDragger'    ],    mixins: {        floating: 'Ext.util.Floating'    },    statics: {        // Collapse/expand directions        DIRECTION_TOP: 'top',        DIRECTION_RIGHT: 'right',        DIRECTION_BOTTOM: 'bottom',        DIRECTION_LEFT: 'left',        VERTICAL_DIRECTION_Re: /^(?:top|bottom)$/,        // RegExp whih specifies characters in an xtype which must be translated to '-' when generating auto IDs.        // This includes dot, comma and whitespace        INVALID_ID_CHARS_Re: /[\.,\s]/g    },    /* End Definitions */<span id='Ext-Component-cfg-resizable'>    /**</span>     * @cfg {Boolean/Object} resizable     * Specify as `true` to apply a {@link Ext.resizer.Resizer Resizer} to this Component after rendering.     *     * May also be specified as a config object to be passed to the constructor of {@link Ext.resizer.Resizer Resizer}     * to override any defaults.
