public class DraggableLabel
extends HTML

A label object that can be dragged and dropped into a DroppableList. The label consists of a name and optionally, an icon to the left of the name. This label can be dragged by holding the mouse button down and by moving the pointer. The object can be dropped into a DroppableList object.

The draggable/droppable classes use the scriptaculous javascript library for providing the functionality. Therefore, you must add the following segment to your application HTML file (see the GWTCompExamples.html for an example).

       <script src="gwtcomp-scripts/scriptaculous/prototype.js" type="text/javascript"></script>
       <script src="gwtcomp-scripts/scriptaculous/scriptaculous.js" type="text/javascript"></script>
       <script src="gwtcomp-scripts/scriptaculous/dragdrop.js" type="text/javascript"></script>
 

CSS Style Rules:

• .gwtcomp-DraggableLabel { } - style for the label
