Type Parameters:

T - the Element type associated

public class LazyDomElement<T extends Element>
extends java.lang.Object

Usage example:

Template:

   <gwt:HTMLPanel>
      <div ui:field="myDiv" />
   </gwt:HTMLPanel>
 

Class:

   @UiField LazyDomElement<DivElement> myDiv;

   public setText(String text) {
     myDiv.get().setInnerHtml(text);
   }
