Defined in:

Overview

This class is a helper to VR::ListView and VR::TreeView. When

colums are created, this class is used as the renderer because
it adds functionality to the Gtk Renderer.

When you call ListView#render(model_col) an instance of this class
will be returned.  It is a subclass of

{Gtk::CellRendererText}[http://ruby-gnome2.sourceforge.jp/hiki.cgi?Gtk%3A%3ACellRendererText]

So it has all the functionality of its parent, plus the methods listed here.
