+ * @targets: (allow-none) (array length=n_targets): a pointer to an array of #GtkTargetEntry<!-- -->s
+ * indicating the drop types that this @widget will accept, or %NULL.
+ * Later you can access the list with gtk_drag_dest_get_target_list()

+ * @n_targets: the number of entries in @targets
+ * @actions: a bitmask of possible actions for a drop onto this @widget.
+ *
+ * Sets a widget as a potential drop destination, and adds default behaviors.
+ *
+ * The default behaviors listed in @flags have an effect similar
+ * to installing default handlers for the widget's drag-and-drop signals
+ * (#GtkWidget:drag-motion, #GtkWidget:drag-drop, ...). They all exist
+ * for convenience. When passing #GTK_DEST_DEFAULT_ALL for instance it is
+ * sufficient to connect to the widget's #GtkWidget::drag-data-received
+ * signal to get primitive, but consistent drag-and-drop support.
+ *
+ * Things become more complicated when you try to preview the dragged data,
+ * as described in the documentation for #GtkWidget:drag-motion. The default
+ * behaviors described by @flags make some assumptions, that can conflict
+ * with your own signal handlers. For instance #GTK_DEST_DEFAULT_DROP causes
+ * invokations of gdk_drag_status() in the context of #GtkWidget:drag-motion,
+ * and invokations of gtk_drag_finish() in #GtkWidget:drag-data-received.
+ * Especially the later is dramatic, when your own #GtkWidget:drag-motion
+ * handler calls gtk_drag_get_data() to inspect the dragged data.
+ *
+ * There's no way to set a default action here, you can use the
+ * #GtkWidget:drag-motion callback for that. Here's an example which selects
+ * the action to use depending on whether the control key is pressed or not:
