<summary>A widget for displaying both trees and lists.</summary>
<remarks>
<para>
Widget that displays any object that implements the
<see cref="T:Gtk.TreeModel"/> interface.
</para>
<para>
To create a tree or list in GTK#, you need to use the <see
cref="T:Gtk.TreeModel"/> interface, in conjunction with the
<see cref="T:Gtk.TreeView"/> widget. This widget is designed around a
Model/View/Controller design and consists of four major parts:
<list type="bullet">
<item><see cref="T:Gtk.TreeView"/>, the tree view widget</item>
<item><see cref="T:Gtk.TreeViewColumn"/>, the view column.</item>
<item>The cell renderers (<see cref="T:Gtk.CellRenderer"/>
and others).</item>
<item><see cref="T:Gtk.TreeModel"/>, the model interface.</item>
</list>
</para>
<para>
The View is composed of the first three, while the last is the
Model. One of the prime benefits of the MVC design is that
multiple views can be created of a single model. For example,
a model mapping the file system could be created for a file
manager. Many views could be created to display various parts
of the file system, but only one copy need be kept in memory.
</para>
<para>
The purpose of the cell renderers is to provide extensibility
to the widget and to allow multiple ways of rendering the same
type of data. For example, consider how to render a boolean
variable. Should you render it as a string of "True" or
"False", "On" or "Off", or should you render it as a checkbox?
