Class Ext.Shadow

Package:	Ext
Class:	Shadow
Extends:	Object
Defined In:	Shadow.js

Simple class that can provide a shadow effect for any element. Note that the element MUST be absolutely positioned, and the shadow does not provide any shimming. This should be used only in simple cases -- for more advanced functionality that can also provide the same shadow effect, see the Ext.Layer class.
