ArrowProtocol
public protocol ArrowProtocol : MiscProtocol
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 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()
.
GtkArrow has been deprecated; you can simply use a GtkImage
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.
The ArrowProtocol
protocol exposes the methods and properties of an underlying GtkArrow
instance.
The default implementation of these can be found in the protocol extension below.
For a concrete class that implements these methods and properties, see Arrow
.
Alternatively, use ArrowRef
as a lighweight, unowned
reference if you already have an instance you just want to use.
