       XmDropTransfer -- The DropTransfer widget class

       #include <Xm/DragDrop.h>

       DropTransfer  provides  a  set  of resources that identifies the procedures and associated
       information required by the toolkit in order to process and complete a  drop  transaction.
       Clients should not explicitly create a DropTransfer widget.  Instead, a client initiates a
       transfer by calling XmDropTransferStart, which initializes and returns a DropTransfer wid-
       get.  If  this function is called within an XmNdropProc callback, the actual transfers are
       initiated after the callback returns. Even if no data needs  to	be  transferred,  XmDrop-
       TransferStart  needs  to be called (typically with no arguments, or just setting XmNtrans-
       ferStatus) to finish the drag and drop transaction.

       The XmNdropTransfers resource specifies a transfer list that describes the requested  tar-
       get  types  for	the  source  data.  A transfer list is an array of XmDropTransferEntryRec
       structures, each of which identifies a target type. The transfer list is analogous to  the
       MULTIPLE  selections capability defined in the Inter-Client Communication Conventions Man-
       ual (ICCCM).

       The DropTransfer resource, XmNtransferProc, specifies a transfer procedure of  type  XtSe-
       lectionCallbackProc that delivers the requested selection data. This procedure operates in
       conjunction with the underlying Xt selection capabilities and is called for each target in
       the  transfer list. Additional target types can be requested after a transfer is initiated
       by calling the XmDropTransferAdd function.

       An XmDropTransferEntry is a pointer to the following structure of  type	XmDropTransferEn-
       tryRec, which identifies a selection target associated with a given drop transaction:

       typedef struct
	       XtPointer       client_data;
	       Atom target;
       } XmDropTransferEntryRec, *XmDropTransferEntry;

		 Specifies any additional information required by this selection target

       target	 Specifies a selection target associated with the drop operation

       DropTransfer inherits behavior and a resource from Object.

       The class pointer is xmDropTransferObjectClass.

       The class name is XmDropTransfer.

   New Resources
       The  following  table  defines a set of widget resources used by the programmer to specify
       data. The programmer can also set the resource values for the  inherited  classes  to  set
       attributes  for	this  widget. To reference a resource by name or by class in a .Xdefaults
       file, remove the XmN or XmC prefix and use the remaining letters. To specify  one  of  the
       defined	values	for  a	resource  in  a .Xdefaults file, remove the Xm prefix and use the
       remaining letters (in either lowercase or uppercase, but include any  underscores  between
       words).	The  codes in the access column indicate if the given resource can be set at cre-
       ation time (C), set by using XtSetValues (S), retrieved by using XtGetValues  (G),  or  is
       not applicable (N/A).

       |		    |		   XmDropTransfer Resource Set	     |			  |	   |
       |Name		    | Class		  | Type		     | Default		  | Access |
       |XmNdropTransfers    | XmCDropTransfers	  | XmDropTransferEntryRec * | NULL		  | CG	   |
       |XmNincremental	    | XmCIncremental	  | Boolean		     | False		  | CSG    |
       |XmNnumDropTransfers | XmCNumDropTransfers | Cardinal		     | 0		  | CSG    |
       |XmNtransferProc     | XmCTransferProc	  | XtSelectionCallbackProc  | NULL		  | CSG    |
       |XmNtransferStatus   | XmCTransferStatus   | unsigned char	     | XmTRANSFER_SUCCESS | CSG    |
		 Specifies  the  address  of  an  array  of drop transfer entry records. The drop
		 transfer is complete when all the entries in the list have been processed.

		 Specifies a Boolean value that indicates whether the transfer	on  the  receiver
		 side uses the Xt incremental selection transfer mechanism described in X Toolkit
		 Intrinsics--C Language Interface.  If the  value  is  True,  the  receiver  uses
		 incremental transfer; if the value is False, the receiver uses atomic transfer.

		 Specifies  the number of entries in XmNdropTransfers. If this resource is set to
		 0 at any time, the transfer is considered complete. The value of XmNtransferSta-
		 tus determines the completion handshaking process.

		 Specifies   a	procedure  of  type  XtSelectionCallbackProc  that  delivers  the
		 requested selection values.  The widget argument passed to this procedure is the
		 DropTransfer  widget.	The selection atom passed is _MOTIF_DROP.  For additional
		 information on selection callback procedures, see X Toolkit  Intrinsics--C  Lan-
		 guage Interface.

		 Specifies the current status of the drop transfer. The client updates this value
		 when the transfer ends and communicates the value to the initiator. The possible
		 values are

			   The transfer succeeded.

			   The transfer failed.

   Inherited Resources
       DropTransfer  inherits behavior and a resource from Object.  For a complete description of
       this resource, refer to the Object reference page.

       |		   |	Object Resource Set	  |	    |	     |
       |Name		   | Class	 | Type 	  | Default | Access |
       |XmNdestroyCallback | XmCCallback | XtCallbackList | NULL    | C      |
       Object(3), XmDisplay(3), XmDragContext(3), XmDragIcon(3),  XmDropSite(3),  XmDropTransfer-
       Add(3), and XmDropTransferStart(3).
