- * @class Ext.Layer
- * @extends Ext.Element
- * An extended {@link Ext.Element} object that supports a shadow and shim, constrain to viewport and
- * automatic maintaining of shadow/shim positions.
- * @cfg {Boolean} shim False to disable the iframe shim in browsers which need one (defaults to true)
- * @cfg {String/Boolean} shadow True to automatically create an {@link Ext.Shadow}, or a string indicating the
- * shadow's display {@link Ext.Shadow#mode}. False to disable the shadow. (defaults to false)
- * @cfg {Object} dh DomHelper object config to create element with (defaults to {tag: 'div', cls: 'x-layer'}).
- * @cfg {Boolean} constrain False to disable constrain to viewport (defaults to true)
- * @cfg {String} cls CSS class to add to the element
- * @cfg {Number} zindex Starting z-index (defaults to 11000)
- * @cfg {Number} shadowOffset Number of pixels to offset the shadow (defaults to 4)
- * @cfg {Boolean} useDisplay
- * Defaults to use css offsets to hide the Layer. Specify <tt>true</tt>
- * to use css style <tt>'display:none;'</tt> to hide the Layer.
- * @constructor
- * @param {Object} config An object with config options.
- * @param {String/HTMLElement} existingEl (optional) Uses an existing DOM element. If the element is not found it creates it.
