     NAME
          XmDragStart - A Drag and Drop function that initiates a drag
          and drop transaction

     SYNOPSIS
          #include <Xm/DragDrop.h>

          Widget XmDragStart (widget, event, arglist, argcount)
               Widget         widget;
               XEvent         *event;
               ArgList        arglist;
               Cardinal       argcount;

     DESCRIPTION
          XmDragStart initiates a drag operation.  This routine
          returns the DragContext widget that it initializes for the
          associated drag transaction.  The toolkit is responsible for
          freeing the DragContext when the drag and drop transaction
          is complete.

          widget
               Specifies the ID of the smallest widget and/or gadget
               that encloses the source elements selected for a drag
               operation.

          event
               Specifies the XEvent that triggered the drag operation.
               This event must be a ButtonPress event.

          arglist
               Specifies the argument list.  Any XmDragContext
               resources not specified in the argument list are
               obtained from the resource database or are set to their
               default values.

          argcount
               Specifies the number of attribute/value pairs in the
               argument list (arglist)

          For a complete definition of DragContext and its associated
          resources, see XmDragContext(3X).

     RETURN VALUE
          Returns the ID of the DragContext widget that controls this
          drag and drop transaction.
