Detailed Description

Renders a pixbuf in a cell.

A CellRendererPixbuf can be used to render an image in a cell. It allows you to render either a given Pixbuf (set via the pixbuf property) or a named icon (set via the icon_name property).

To support the tree view, CellRendererPixbuf also supports rendering two alternative pixbufs, when the is_expanded 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.

Deprecated:
4.10: List views use widgets to display their contents. You should use Gtk::Image for icons, and Gtk::Picture for images.
