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 ammended 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().
typedef struct _GtkArrow GtkArrow;
The GtkArrow struct containes the following fields. (These fields should be considered read-only. They should never be set by an application.)
GtkWidget* gtk_arrow_new (GtkArrowType arrow_type, GtkShadowType shadow_type);
Creates a new arrow widget.
arrow_type : |

void gtk_arrow_set (GtkArrow *arrow, GtkArrowType arrow_type, GtkShadowType shadow_type);
Sets the direction and style of the GtkArrow, arrow.
