NAME
       Dt/Dnd.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,
	       Pixmap mask);

       Widget DtDndDragStart(Widget dragSource,
	       XEvent *event,
	       DtDndProtocol protocol,
	       Cardinal	numItems,
	       unsigned	char operations,
	       XtCallbackList convertCallback,
	       XtCallbackList dragFinishCallback,
	       ArgList argList,
	       Cardinal	argCount);

       Widget DtDndVaDragStart(Widget dragSource,
	       XEvent *event,
	       DtDndProtocol protocol,
	       Cardinal	numItems,
	       unsigned	char operations,
	       XtCallbackList convertCallback,
	       XtCallbackList dragFinishCallback,
	       ...);

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

       void DtDndVaDropRegister(Widget dropSite,
	       DtDndProtocol protocols,
	       unsigned	char operations,
	       XtCallbackList transferCallback,
	       ...);

       void DtDndDropUnregister(Widget dropSite);
