CellRendererPixbufProtocol
public protocol CellRendererPixbufProtocol : CellRendererProtocol
Renders a pixbuf in a cell
A GtkCellRendererPixbuf
can be used to render an image in a cell. It allows
to render either a given GdkPixbuf
(set via the
GtkCellRendererPixbuf:pixbuf
property) or a named icon (set via the
GtkCellRendererPixbuf:icon-name
property).
To support the tree view, GtkCellRendererPixbuf
also supports rendering two
alternative pixbufs, when the GtkCellRenderer:is-expander
property is true
.
If the GtkCellRenderer:is-expanded property
is true
and the
GtkCellRendererPixbuf:pixbuf-expander-open
property is set to a pixbuf, it
renders that pixbuf, if the GtkCellRenderer:is-expanded
property is false
and the GtkCellRendererPixbuf:pixbuf-expander-closed
property is set to a
pixbuf, it renders that one.
The CellRendererPixbufProtocol
protocol exposes the methods and properties of an underlying GtkCellRendererPixbuf
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 CellRendererPixbuf
.
Alternatively, use CellRendererPixbufRef
as a lighweight, unowned
reference if you already have an instance you just want to use.
