An arrow pointing in one of the four cardinal directions.
None.
The GtkArrow widget is a drawn triangle that has its "nose" pointing in the direction specified during construction. The look of the arrow is varied through the choice of GtkShadowType, and it inherits from the GtkMisc class the ability to have its own padding and alignment properties altered directly, both of which can also have a surprisingly big impact on the arrow's appearance.
GtkArrow ( GtkArrowType arrow_type , GtkShadowType shadow_type );-- Displays an arrow pointing in one of the four cardinal directions.
