Renders a pixbuf in a cell
Class GtkCellRendererPixbuf
A GtkCellRendererPixbuf can be used to render an image in a cell. It allows to render either a given GdkPixbuf (set via the pixbuf property) or a stock icon (set via the stock-id property).
To support the tree view, GtkCellRendererPixbuf also supports rendering two alternative pixbufs, when the is-expander property is TRUE. If the is-expanded property is TRUE and the pixbuf-expander-open property is set to a pixbuf, it renders that pixbuf, if the is-expanded property is FALSE and the pixbuf-expander-closed property is set to a pixbuf, it renders that one.
