41 * GtkDestDefaults:
42 * @GTK_DEST_DEFAULT_MOTION: If set for a widget, GTK+, during a drag over this
43 * widget will check if the drag matches this widget’s list of possible targets
44 * and actions.
45 * GTK+ will then call gdk_drag_status() as appropriate.
46 * @GTK_DEST_DEFAULT_HIGHLIGHT: If set for a widget, GTK+ will draw a highlight on
47 * this widget as long as a drag is over this widget and the widget drag format
48 * and action are acceptable.
49 * @GTK_DEST_DEFAULT_DROP: If set for a widget, when a drop occurs, GTK+ will
50 * will check if the drag matches this widget’s list of possible targets and
51 * actions. If so, GTK+ will call gtk_drag_get_data() on behalf of the widget.
52 * Whether or not the drop is successful, GTK+ will call gtk_drag_finish(). If
53 * the action was a move, then if the drag was successful, then %TRUE will be
54 * passed for the @delete parameter to gtk_drag_finish().
55 * @GTK_DEST_DEFAULT_ALL: If set, specifies that all default actions should
56 * be taken.
57 *
58 * The #GtkDestDefaults enumeration specifies the various
59 * types of action that will be taken on behalf
60 * of the user for a drag destination site.
