public class DefaultDragInfoRenderer extends JPanel implements IDragInfoRenderer, Border
IDragInfoPolicy
that is
currently being used to return an object that can be serialized via a simple
call to Object.toString()
. The renderer contains a text area, which
will display the serialized object. The renderer additionally features a
label at its top, which will use the currently installed ILabelPolicy
to lookup a title via the LabelType.DRAG_INFO_TITLE
