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 Gtk.Misc.Gtk_Misc, it can be padded and/or aligned, to fill exactly the space the programmer desires.
Arrows are created with a call to Gtk.Arrow.Gtk_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 Gtk.Image.Gtk_Image with a suitable icon name, such as "pan-down-symbolic". When replacing GtkArrow by an image, pay attention to the fact that GtkArrow is doing automatic flipping between GTK_ARROW_LEFT and GTK_ARROW_RIGHT, depending on the text direction. To get the same effect with an image, use the icon names "pan-start-symbolic" and "pan-end-symbolic", which react to the text direction.
