XmGetDragContext — A Drag and Drop function that retrieves the DragContext widget ID associated with a

XmGetDragContext returns the widget ID of the active DragContext associated  with  a  given  display  and
       timestamp.  A  timestamp uniquely identifies which DragContext is active when more than one drag and drop
       transaction has been initiated on a display. If the specified timestamp  matches  a  timestamp  processed
       between  the  start  and  finish  of  a  single  drag  and  drop  transaction,  the  function returns the
       corresponding DragContext ID.

       refwidget Specifies the ID of the widget that the routine uses to  identify  the  intended  display.  The
                 function  returns  the  ID  of the DragContext associated with the display value passed by this
                 widget.

       timestamp Specifies a timestamp.
