    NAME
         DtDnd.h - Drag and drop definitions
    
    SYNOPSIS
         #include <Dt/Dnd.h>
    
    DESCRIPTION
         The <Dt/Dnd.h>  header  defines  the  following  enumeration
         types:
    
              DtCR_DND_CONVERT_DATA
              DtCR_DND_CONVERT_DELETE
              DtCR_DND_DRAG_FINISH
              DtCR_DND_TRANSFER_DATA
              DtCR_DND_DROP_ANIMATE
    
         The header defines the  following  enumeration  data  types,
         with at least the following members:
    
            DtDndStatus
                  DtDND_SUCCESS, DtDND_FAILURE
    
            DtDndProtocol
    
                       DtDND_TEXT_TRANSFER     = (1L << 0)
                       DtDND_FILENAME_TRANSFER = (1L << 1)
                       DtDND_BUFFER_TRANSFER   = (1L << 2)
    
         The header declares the following structures:
    
              typedef struct _DtDndBuffer {
                  void *bp;
                  int size;
                  string name;
              } DtDndBuffer;
    
              typedef struct _DtDndContext {
                  DtDndProtocol protocol;
                  int numItems;
                  union {
                      XmString *strings;
                      String *files;
                      DtDndBuffer *buffers;
                  } data;
              } DtDndContext;
    
              typedef struct _DtDndConvertCallbackStruct {
                  int reason;
                  XEvent *event;
                  DtDndContext *dragData;
                  DtDndStatus status;
              } DtDndConvertCallbackStruct, *DtDndConvertCallback;
              typedef struct _DtDndDragFinishCallbackStruct {
                  int reason;
                  XEvent *event;
                  DtDndContext *dragData;
                  Widget sourceIcon;
              } DtDndDragFinishCallbackStruct, *DtDndDragFinishCallback;
    
              typedef struct _DtDndTransferCallbackStruct {
                  int reason;
                  XEvent *event;
                  Position x, y;
                  unsigned char operation;
                  DtDndContext *dropData;
                  Boolean completeMove;
                  DtDndStatus status;
              } DtDndTransferCallbackStruct, *DtDndTransferCallback;
    
              typedef struct _DtDndDropAnimateCallbackStruct {
                  int reason;
                  XEvent *event;
                  Position x, y;
                  unsigned char operation;
                  DtDndContext *dropData;
              } DtDndDropAnimateCallbackStruct, *DtDndDropAnimateCallback;
    
         The header declares the following as functions:
    
         Widget DtDndCreateSourceIcon(Widget parent,
                                      Pixmap pixmap,

                               Cardinal numItems,
                               unsigned char operations,
                               XtCallbackList convertCallback,
                               XtCallbackList dragFinishCallback,
                               ArgList argList,

                                 Cardinal numItems,
                                 unsigned char operations,
                                 XtCallbackList convertCallback,
                                 XtCallbackList dragFinishCallback,
                                 ...);

                                DtDndProtocol protocols,
                                unsigned char operations,
                                XtCallbackList transferCallback,
                                ArgList argList,
                                Cardinal argCount);
    
         void DtDndVaDropRegister(Widget dropSite,
