NAME
       XmDragStart — A Drag and Drop function that initiates a drag and drop
       transaction

SYNOPSIS
       #include <Xm/DragDrop.h>
       Widget XmDragStart(
       Widget widget,
       XEvent *event,
       ArgList arglist,
       Cardinal argcount);

DESCRIPTION
       XmDragStart initiates a drag operation. This routine returns the
       DragContext widget that it initializes for the associated drag
       transaction. The toolkit is responsible for freeing the DragContext
       when the drag and drop transaction is complete.

       widget    Specifies the ID of the smallest widget and/or gadget that
                 encloses the source elements selected for a drag operation.

       event     Specifies the XEvent that triggered the drag operation. This
                 event must be a ButtonPress event.

       arglist   Specifies the argument list. Any XmDragContext resources not
                 specified in the argument list are obtained from the resource
                 database or are set to their default values.

       argcount  Specifies the number of attribute/value pairs in the argument
                 list (arglist)

       For a complete definition of DragContext and its associated resources,
       see XmDragContext(3).

RETURN
       Returns the ID of the DragContext widget that controls this drag and
       drop transaction.  Returns NULL if the drag cannot be initiated.
