+ * @Short_description: Displays an arrow
+ * @Title: GtkArrow
+ * @See_also: gtk_render_arrow()
+ *
+ * GtkArrow should be used to draw simple arrows that need to point in
+ * one of the four cardinal directions (up, down, left, or right). The
+ * style of the arrow can be one of shadow in, shadow out, etched in, or
+ * etched out. Note that these directions and style types may be
+ * amended in versions of GTK+ to come.
+ *
+ * GtkArrow will fill any space alloted to it, but since it is inherited
+ * from #GtkMisc, it can be padded and/or aligned, to fill exactly the
+ * space the programmer desires.
+ *
+ * Arrows are created with a call to gtk_arrow_new(). The direction or
+ * style of an arrow can be changed after creation by using gtk_arrow_set().
+ *
+ * GtkArrow has been deprecated; you can simply use a #GtkImage with a
+ * suitable icon name, such as “pan-down-symbolic“.
