<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>This class defines a generic tree interface for use by the <a class="el" href="classGtk_1_1TreeView.html" title="The TreeView widget displays the model (Gtk::TreeModel) data and allows the user...">Gtk::TreeView</a> widget. </p>
<p>It is is designed to be usable with any appropriate data structure. The programmer just has to implement this interface on their own data type for it to be viewable by a <a class="el" href="classGtk_1_1TreeView.html" title="The TreeView widget displays the model (Gtk::TreeModel) data and allows the user...">Gtk::TreeView</a> widget.</p>
<p>The model is represented as a hierarchical tree of strongly-typed, columned data. In other words, the model can be seen as a tree where every node has different values depending on which column is being queried. The type of data found in a column is determined by TreeModel::Column<> templates. The types are homogeneous per column across all nodes. 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>In order to make life simpler for programmers who do not need to write their own specialized model, two generic models are provided - the <a class="el" href="classGtk_1_1TreeStore.html">Gtk::TreeStore</a> and the <a class="el" href="classGtk_1_1ListStore.html" title="Thist is a list model for use with a Gtk::TreeView widget.">Gtk::ListStore</a>. To use these, the developer simply pushes data into these models as necessary. These models provide the data structure as well as all appropriate tree interfaces. As a result, implementing drag and drop, sorting, and storing data is trivial. For the vast majority of trees and lists, these two models are sufficient.</p>
<p>Models are accessed on a node/column level of granularity. One can query for the value of a model at a certain node and a certain column on that node. There are two structures used to reference a particular node in a model. They are the <a class="el" href="classGtk_1_1TreePath.html">Path</a> and the iterator. Most of the interface consists of operations on an <a class="el" href="classGtk_1_1TreeIter.html">iterator</a>.</p>
<p>A <a class="el" href="classGtk_1_1TreePath.html">Gtk::TreeModel::Path</a> 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.</p>
<p>By contrast, an <a class="el" href="classGtk_1_1TreeIter.html">Gtk::TreeModel::iterator</a> is a reference to a specific node on a specific model. One can convert a path to an <a class="el" href="classGtk_1_1TreeIter.html">iterator</a> by calling <a class="el" href="classGtk_1_1TreeModel.html#aebaa795e4920ddc0ec5e39c9f4fbc660" title="Returns a valid iterator pointing to path.">Gtk::TreeModel::get_iter()</a>. These iterators are the primary way of accessing a model and are similar to the iterators used by <a class="el" href="classGtk_1_1TextBuffer.html" title="Multi-line attributed text that can be displayed by one or more Gtk::TextView widgets...">Gtk::TextBuffer</a>. The model interface defines a set of operations using them for navigating the model.</p>
<p>The <a class="el" href="classGtk_1_1TreeRowReference.html">RowReference</a> is also useful, because it remains valid as long as there is an existing row pointed to by it's path. You can convert between RowReferences and iterators and <a class="el" href="classGtk_1_1TreePath.html">Path</a> s. </p>

<p>This function is primarily meant as a way for views to let caching model know when nodes are being displayed (and hence, whether or not to cache that node.) For example, a file-system based model would not want to keep the entire file-hierarchy in memory, just the sections that are currently being displayed by every current view.</p>
