renderer - public static <T> ValueLabel<T> wrap(Element element, Renderer<? super T> renderer)
The ValueLabel's value will be null, whether the element being
wrapped has content or not. Use wrap(Element, Renderer, Parser) to
parse the initial element's content to initialize the ValueLabel's value.
This element must already be attached to the document. If the element is
removed from the document, you must call
RootPanel.detachNow(Widget).

The ValueLabel's value will be initialized with the element's content,
passed through the parser.
