The example code shown on the http://docs.telerik.com/kendo-ui/web/window/how-to/use-custom-action-icons page titled "Use custom actions icons" seems to be a splitter example and has nothing on it relating to the custom icons for a window widget usage.
Can someone point me to a actual example of using custom icons on a window?
The ones I have found say to use a .wrapper, but when I try to associate a .wrapper in our testing it always says its an unknown and throws a error in the console.
Thanks
