11 * Provides skin related utlility methods.
14 * @submodule widget-skin
16 var BOUNDING_BOX = "boundingBox",
17 CONTENT_BOX = "contentBox",
19 _getClassName = Y.ClassNameManager.getClassName;
22 * Returns the name of the skin that's currently applied to the widget.
24 * Searches up the Widget's ancestor axis for, by default, a class
25 * yui3-skin-(name), and returns the (name) portion. Otherwise, returns null.
27 * This is only really useful after the widget's DOM structure is in the
28 * document, either by render or by progressive enhancement.
32 * @param {String} [skinPrefix] The prefix which the implementation uses for the skin
33 * ("yui3-skin-" is the default).
35 * NOTE: skinPrefix will be used as part of a regular expression:
37 * new RegExp('\\b' + skinPrefix + '(\\S+)')
39 * Although an unlikely use case, literal characters which may result in an invalid
40 * regular expression should be escaped.
42 * @return {String} The name of the skin, or null, if a matching skin class is not found.
