Overview

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.

Constructor Details

#initialize ⇒ Gtk::CellRenderer

Creates a new GtkCellRendererPixbuf. Adjust rendering parameters using object properties. Object properties can be set globally (with g_object_set()). Also, with GtkTreeViewColumn, you can bind a property to a value in a GtkTreeModel. 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 GtkTreeView.
