<hr><a name="_details"></a><h2>Detailed Description</h2>
Typedefed as <a class="el" href="classGtk_1_1TreeModel.html#s0">TreeModel::ColumnRecord</a>.
<p>
Keeps a record of <a class="el" href="classGtk_1_1TreeModelColumn.html">TreeModelColumns</a>. ColumnRecord objects are used to setup a new <a class="el" href="classGtk_1_1TreeModel.html">TreeModel</a> (or rather, an implementation of the model, like <a class="el" href="classGtk_1_1ListStore.html">Gtk::ListStore</a> or Gtk::TreeStore). It is convenient to do that by deriving from TreeModel::ColumnRecord: <div class="fragment"><pre>
<span class="keyword">class </span>MyModelColumns : <span class="keyword">public</span> Gtk::TreeModel::ColumnRecord
{
<span class="keyword">public</span>:
<a class="code" href="classGtk_1_1TreeModelColumn.html">Gtk::TreeModelColumn<Glib::ustring></a> filename;
<a class="code" href="classGtk_1_1TreeModelColumn.html">Gtk::TreeModelColumn<Glib::ustring></a> description;
<a class="code" href="classGtk_1_1TreeModelColumn.html">Gtk::TreeModelColumn< Glib::RefPtr<Gdk::Pixbuf></a> > thumbnail;
MyModelColumns() { <a class="code" href="classGtk_1_1TreeModelColumnRecord.html#a2">add</a>(filename); <a class="code" href="classGtk_1_1TreeModelColumnRecord.html#a2">add</a>(description); <a class="code" href="classGtk_1_1TreeModelColumnRecord.html#a2">add</a>(thumbnail); }
};
</pre></div>An instance of <code>MyModelColumns</code> should be passed to <a class="el" href="classGtk_1_1ListStore.html#d0">ListStore::create()</a> or <a class="el" href="classGtk_1_1TreeStore.html#d0">TreeStore::create()</a>. 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#a0">Gtk::TreeRow::operator[]()</a> to specify the column you're interested in.
<p>
Neither <a class="el" href="classGtk_1_1TreeModel.html#s0">TreeModel::ColumnRecord</a> nor the <a class="el" href="classGtk_1_1TreeModelColumn.html">TreeModelColumns</a> contain any real data -- it's merely a description of what type is stored in which column of a <a class="el" href="classGtk_1_1TreeModel.html">TreeModel</a>. Thus it's absolutely legal to use a statically allocated <a class="el" href="classGtk_1_1TreeModel.html#s0">TreeModel::ColumnRecord</a> (as long as you make sure it's instantiated after Gtk::Main), even when creating multiple models from it.
