NAME
     DtDndCreateSourceIcon - create a drag source icon

SYNOPSIS
     #include <Dt/Dnd.h>
     Widget DtDndCreateSourceIcon(Widget parent,
                                  Pixmap pixmap,
                                  Pixmap mask);

DESCRIPTION
     The DtDndCreateSourceIcon() function creates  a  Motif  drag
     icon,  named sourceIcon, based on the characteristics of the
     pixmap argument.  The resulting drag icon  is  suitable  for
     use with DtDndDragStart(3).

     The parent argument is the parent of the drag  icon.   Typi-
     cally this widget is the drag source.

     The pixmap argument is the pixmap representation of the data
     to be dragged.

     The mask argument is the mask for the pixmap.

     When it calls XmCreateDragIcon(3X), the  DtDndCreateSourceI-
     con()  function  sets  Motif resources in the drag icon; the
     application must not modify  the  values  of  any  of  these
     resources:

          XmNwidth
          XmNheight
          XmNpixmap
          XmNmask
          XmNdepth

RETURN VALUE
     Upon  successful  completion,  the   DtDndCreateSourceIcon()
     function   returns   a   drag   icon   created   by  calling
     XmCreateDragIcon(3X) with the characteristics of the pixmap;
     otherwise, it returns NULL.
