<p>Keeps a record of <a class="el" href="classGtk_1_1TreeModelColumn.html">TreeModelColumns</a>.</p>
<p>ColumnRecord objects are used to setup a new instance of a <a class="el" href="classGtk_1_1TreeModel.html" title="This class defines a generic tree interface for use by the Gtk::TreeView widget.">TreeModel</a> (or rather, a new instance of an implementation of the model, such as <a class="el" href="classGtk_1_1ListStore.html" title="Thist is a list model for use with a Gtk::TreeView widget.">Gtk::ListStore</a> or <a class="el" href="classGtk_1_1TreeStore.html">Gtk::TreeStore</a>). It is convenient to do that by deriving from <a class="el" href="classGtk_1_1TreeModel.html#a58f10daabaa507b4c2473c9d1b6fa584">TreeModel::ColumnRecord</a>: </p>

};
</pre></div><p>Whether or not you derive your own ColumnRecord, you need to add the <a class="el" href="classGtk_1_1TreeModelColumn.html">TreeModelColumns</a> to the ColumnRecord with the <a class="el" href="classGtk_1_1TreeModelColumnRecord.html#a7084fc10fa1abf0d7317558b8462559f" title="Adds a TreeModelColumn to this record.">add()</a> method.</p>
<p>A ColumnRecord instance, such as an instance of <code>MyModelColumns</code> should then be passed to <a class="el" href="classGtk_1_1ListStore.html#aaa6c530560f66872482a0650739276c5" title="Instantiate a new ListStore.">ListStore::create()</a> or <a class="el" href="classGtk_1_1TreeStore.html#a65fc563bfbef2f1a31028cd33ff228c0" title="Instantiate a new TreeStore.">TreeStore::create()</a>. The <a class="el" href="classGtk_1_1TreeModelColumn.html">TreeModelColumns</a>, such as the members <code>filename</code>, <code>description</code> and <code>thumbnail</code> can then be used with <a class="el" href="classGtk_1_1TreeRow.html#ad1880375e2c3b45a6ba69b225dd7f6a4" title="Use this to set and get the value of this column of this row.">Gtk::TreeRow::operator[]()</a> to specify the column you're interested in.</p>
<p>Neither <a class="el" href="classGtk_1_1TreeModel.html#a58f10daabaa507b4c2473c9d1b6fa584">TreeModel::ColumnRecord</a> nor the <a class="el" href="classGtk_1_1TreeModelColumn.html">TreeModelColumns</a> contain any real data -- they merely describe what C++ type is stored in which column of a <a class="el" href="classGtk_1_1TreeModel.html" title="This class defines a generic tree interface for use by the Gtk::TreeView widget.">TreeModel</a>, and save you from having to repeat that type information in several places.</p>
<p>Thus <a class="el" href="classGtk_1_1TreeModel.html#a58f10daabaa507b4c2473c9d1b6fa584">TreeModel::ColumnRecord</a> can be made a singleton (as long as you make sure it's instantiated after <a class="el" href="classGtk_1_1Main.html" title="Main application class Every application must have one of these objects.">Gtk::Main</a>), even when creating multiple models from it. </p>
