-/**\r
- * @class Ext.BoxComponent\r
- * @extends Ext.Component\r
- * <p>Base class for any visual {@link Ext.Component} that uses a box container. BoxComponent provides automatic box\r
- * model adjustments for sizing and positioning and will work correctly withnin the Component rendering model. All\r
- * container classes should subclass BoxComponent so that they will work consistently when nested within other Ext\r
- * layout containers.</p>\r
- * <p>A BoxComponent may be created as a custom Component which encapsulates any HTML element, either a pre-existing\r
- * element, or one that is created to your specifications at render time. Usually, to participate in layouts,\r
- * a Component will need to be a <b>Box</b>Component in order to have its width and height managed.</p>\r
- * <p>To use a pre-existing element as a BoxComponent, configure it so that you preset the <b>el</b> property to the\r
- * element to reference:<pre><code>\r
-var pageHeader = new Ext.BoxComponent({\r
- el: 'my-header-div'\r
-});</code></pre>\r
- * This may then be {@link Ext.Container#add added} to a {@link Ext.Container Container} as a child item.</p>\r
- * <p>To create a BoxComponent based around a HTML element to be created at render time, use the\r
- * {@link Ext.Component#autoEl autoEl} config option which takes the form of a\r
- * {@link Ext.DomHelper DomHelper} specification:<pre><code>\r
-var myImage = new Ext.BoxComponent({\r
- autoEl: {\r
- tag: 'img',\r
- src: '/images/my-image.jpg'\r
- }\r
-});</code></pre></p>\r

- * @param {Ext.Element/String/Object} config The configuration options.\r
