| * @GTK_DEST_DEFAULT_HIGHLIGHT: If set for a widget, GTK+ will draw a highlight on |

| * 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. |
