+ * GtkDestDefaults:
+ * @GTK_DEST_DEFAULT_MOTION: If set for a widget, GTK+, during a drag over this
+ * widget will check if the drag matches this widget's list of possible targets
+ * and actions.
+ * GTK+ will then call gdk_drag_status() as appropriate.
+ * @GTK_DEST_DEFAULT_HIGHLIGHT: If set for a widget, GTK+ will draw a highlight on
+ * this widget as long as a drag is over this widget and the widget drag format
+ * and action are acceptable.
+ * @GTK_DEST_DEFAULT_DROP: If set for a widget, when a drop occurs, GTK+ will
+ * will check if the drag matches this widget's list of possible targets and
+ * actions. If so, GTK+ will call gtk_drag_get_data() on behalf of the widget.
+ * Whether or not the drop is successful, GTK+ will call gtk_drag_finish(). If
+ * the action was a move, then if the drag was successful, then %TRUE will be
+ * passed for the @delete parameter to gtk_drag_finish().
+ * @GTK_DEST_DEFAULT_ALL: If set, specifies that all default actions should
+ * be taken.
+ *
+ * The #GtkDestDefaults enumeration specifies the various
+ * types of action that will be taken on behalf
+ * of the user for a drag destination site.
