class Gtk::CellRendererPixbuf

Overview

Renders a pixbuf in a cell

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

To support the tree view, Gtk::CellRendererPixbuf also supports rendering two alternative pixbufs, when the Gtk::CellRenderer:is-expander property is true. If the Gtk::CellRenderer:is-expanded property is true and the Gtk::CellRendererPixbuf:pixbuf-expander-open property is set to a pixbuf, it renders that pixbuf, if the Gtk::CellRenderer:is-expanded property is false and the Gtk::CellRendererPixbuf:pixbuf-expander-closed property is set to a pixbuf, it renders that one.

Constructor Detail

def self.new : self #

Creates a new Gtk::CellRendererPixbuf. Adjust rendering parameters using object properties. Object properties can be set globally (with g_object_set()). Also, with Gtk::TreeViewColumn, you can bind a property to a value in a Gtk::TreeModel. For example, you can bind the “pixbuf” property on the cell renderer to a pixbuf value in the model, thus rendering a different image in each row of the Gtk::TreeView.
