>The <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeModel.html#t%3ATreeModel"
>TreeModel</A
></TT
> interface defines a generic storage object for use by the
 <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeView.html#t%3ATreeView"
>TreeView</A
></TT
> and similar widgets. Specifically, the functions in defined here
 are used by Gtk's widgets to access the stored data. Thus, rather than
 calling these functions, an application programmer has to implement them.
 While the module <A HREF="Graphics-UI-Gtk-ModelView-CustomStore.html"
>Graphics.UI.Gtk.ModelView.CustomStore</A
> provides the
 necessary functions to implement the TreeMode interface, it is often
 sufficient to use the wo implementations that come with Gtk2Hs, namely are
 <TT
>ListStore</TT
> and <TT
>TreeStore</TT
>.
</P
><P
>The model is represented as a hierarchical tree of values. It is important
 to note that this interface only provides a way of examining a model and
 observing changes. The implementation of each individual model decides how
 and if changes are made.
</P
><P
>Two generic models are provided that implement the <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeModel.html#t%3ATreeModel"
>TreeModel</A
></TT
> interface:
 the <TT
>TreeStore</TT
> and the <TT
>ListStore</TT
>. To use these, the developer simply
 inserts data into these models as necessary. These models provide the data
 structure as well as the <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeModel.html#t%3ATreeModel"
>TreeModel</A
></TT
> interface. In fact, they implement
 other interfaces, making drag and drop and storing data trivial.
</P
><P
>A <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeModel.html#t%3ATreeModel"
>TreeModel</A
></TT
> stores records of the same type. Each record is referred to
 as row, just like in a relational database. Defining how the information of
 a row is displayed can be done in two ways: If the widget displays data
 using Graphics.UI.Gtk.ModelView.CellRenderer.CellRenderer or one of its
 derivatives, it is possible to state how a row is mapped to the attributes
 of a renderer using the
 Graphics.UI.Gtk.ModelView.CellLayout.cellLayoutSetAttributes function.
 Some widgets do not use
 Graphics.UI.Gtk.ModelView.CellRenderer.CellRenderers to display their
 data. In this case an extraction function can be defined that maps a row to
 one of a few basic types (like <TT
><A HREF="/usr/share/doc/ghc/html/libraries/base-4.2.0.2/Data-Char.html#t%3AString"
>String</A
></TT
>s or <TT
><A HREF="/usr/share/doc/ghc/html/libraries/base-4.2.0.2/Data-Int.html#t%3AInt"
>Int</A
></TT
>s). This extraction
 function is associated with a <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeModel.html#t%3AColumnId"
>ColumnId</A
></TT
> using
 Graphics.UI.Gtk.ModelView.CustomStore.treeModelSetColumn. The latter can
 be set in the widget for the property that should be set. The widget then
 uses the function <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeModel.html#v%3AtreeModelGetValue"
>treeModelGetValue</A
></TT
> and the <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeModel.html#t%3AColumnId"
>ColumnId</A
></TT
> to extract the
 value from the model. As the name suggests, using <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeModel.html#t%3AColumnId"
>ColumnId</A
></TT
>s creates a
 view of the data as if each row were divided into a well-defined set of
 columns, again, like a relational database.
</P
><P
>Models are accessed on a node level of granularity. There are two index
 types used to reference a particular node in a model. They are the
 <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeModel.html#t%3ATreePath"
>TreePath</A
></TT
> and the <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeModel.html#t%3ATreeIter"
>TreeIter</A
></TT
>. Most of the interface consists of operations
 on a <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeModel.html#t%3ATreeIter"
>TreeIter</A
></TT
>.
</P
><P
>A path is essentially a potential node. It is a location on a model that
 may or may not actually correspond to a node on a specific model. A
 <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeModel.html#t%3ATreePath"
>TreePath</A
></TT
> is in fact a synonym for a list of <TT
><A HREF="/usr/share/doc/ghc/html/libraries/base-4.2.0.2/Data-Int.html#t%3AInt"
>Int</A
></TT
>s and hence are easy to
 manipulate. Each number refers to the offset at that level. Thus, the path
 <TT
>[0]</TT
> refers to the root node and the path <TT
>[2,4]</TT
> refers to the fifth
 child of the third node.
</P
><P
>By contrast, a <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeModel.html#t%3ATreeIter"
>TreeIter</A
></TT
> is a reference to a specific node on a specific
 model. It is an abstract data type filled in by the model. One can convert
 a path to an iterator by calling <TT
><A HREF="Graphics-UI-Gtk-ModelView-TreeModel.html#v%3AtreeModelGetIter"
>treeModelGetIter</A
></TT
>. These iterators are
 the primary way of accessing a model and are similar to the iterators used
 by <TT
><A HREF="Graphics-UI-Gtk-Multiline-TextBuffer.html#t%3ATextBuffer"
>TextBuffer</A
></TT
>. The model interface defines a set of operations using them
 for navigating the model. Iterators are expected to always be valid for as
 long as the model is unchanged (and doesn't emit a signal).

>Tree Iterator: a pointer to an entry in a
 Graphics.UI.Gtk.ModelView.TreeModel. The constructor of this structure is
 public for the sake of creating custom tree models. The first value is a
 time stamp that is handled by the functions that interface with Gtk. The
 time stamps are used to print warnings if programmers use an iter to a
 model that has changed meanwhile. The other three fields are used by the
 custom model implementation to implement an indexing scheme. The precise
 use of the three words is therefore implementation specific. See also
