+ * @Short_description: A toplevel to use as drag icon
+ * @Title: GtkDragIcon
+ *
+ * GtkDragIcon is a #GtkNative implementation with the sole purpose
+ * to serve as a drag icon during DND operations. A drag icon moves
+ * with the pointer during a drag operation and is destroyed when
+ * the drag ends.
+ *
+ * To set up a drag icon and associate it with an ongoing drag operation,
+ * use gtk_drag_icon_set_from_paintable(). It is also possible to create
+ * a GtkDragIcon with gtk_drag_icon_new_for_drag(() and populate it
+ * with widgets yourself.
