Produces an arrow pointing in one of the four cardinal directions.
This is intended for use where a directional arrow (in one of the four cardinal directions) is desired. As such, it has very limited functionality and basically only draws itself in a particular direction and with a particular shadow type.
Gtk::Arrow will fill any space alloted to it, but since it is inherited from Gtk::Misc, it can be padded and/or aligned, to fill exactly the space the programmer desires.
