XmDropTransferStart initiates a drop transfer and uses the specified argument list to initialize an XmDropTransfer object. The DropTransfer object can be manipulated with XtSetValues and XtGetValues until the last call to the XmNtransferProc procedure is made. After that point, the result of using the widget pointer is undefined. The DropTransfer object is freed by the toolkit when a transfer is complete.
