GtkArrow produces an arrow pointing in one of the four cardinal directions. 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(). gtk_paint_arrow() the function used internally to paint the arrow. The #GtkArrow-struct containes the following fields. (These fields should be considered read-only. They should never be set by an application.) #gint16 arrow_type; the direction of the arrow, one of #GtkArrowType. #gint16 shadow_type; the style of the arrow, one of #GtkShadowType. Creates a new arrow widget. @arrow_type: a valid #GtkArrowType. @shadow_type: a valid #GtkShadowType. @Returns: the new #GtkArrow widget. Sets the direction and style of the #GtkArrow, @arrow. @arrow: a widget of type #GtkArrow. @arrow_type: a valid #GtkArrowType. @shadow_type: a valid #GtkShadowType.
