#GWT-ValueBoxLabeler
A utillity class that adds whatever text is defined in the title attribute as a background in the text box as long as the user has not entered any value in the widget. The background text can be added to any of the ValueBox based GWT widgets.
When the user enters (focuses) the widget, the background text is removed, when the user leaves (blurs) the widget the background is added again if the text box contains no value.
The text displayed text in the box is defined using the widgets title attribute.
The appearance of the background text is controlled trough the CSS class
Labeled-Text-Box.
Use the class by instantiating a object of it suppling the widget to be labeled to the constructor.
