The gtk-dest-defaults flags specifies the various types of action that will be taken on behalf of the user for a drag destination site.

(define-g-flags "GtkDestDefaults" gtk-dest-defaults
  (:export t
   :type-initializer "gtk_dest_defaults_get_type")
  (:motion 1)
  (:highlight 2)
  (:drop 4)
  (:all 7))  

:motion

If set for a widget, GTK, during a drag over this widget will check if the drag matches the list of possible targets and actions of the widget. GTK will then call the gdk-drag-status function as appropriate.

:highlight

If set for a widget, GTK will draw a highlight on the widget as long as a drag is over this widget and the widget drag format and action are acceptable.

:drop

If set for a widget, when a drop occurs, GTK will will check if the drag matches the list of possible targets and actions of the widget. If so, GTK will call the gtk-drag-data function on behalf of the widget. Whether or not the drop is successful, GTK will call the gtk-drag-finish function. If the action was a move, then if the drag was successful true will be passed for the delete parameter to the gtk-drag-finish function.

:all

If set, specifies that all default actions should be taken.
