<para>The <link
linkend="class-pygtkgenericcellrenderer"><classname>gtk.GenericCellRenderer</classname></link>
helps in the creation of <link
linkend="class-gtktreeview"><classname>gtk.TreeView</classname></link> cell
renderers in Python. The <link
linkend="class-pygtkgenericcellrenderer"><classname>gtk.GenericCellRenderer</classname></link>
is subclassed to provide a new cell renderer that provides cell renderer
behavior using methods with predefined names that are called by the <link
linkend="class-pygtkgenericcellrenderer"><classname>gtk.GenericCellRenderer</classname></link>
methods as required to provide the various cell renderer operations. The
methods that need to be defined by the programmer in Python are:</para>
