NAME

   transaction "XmDragStart" "Drag and Drop functions" "XmDragStart"

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.

             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).
