is an object that implements the Python Iterator protocol. It provides the
means to iterate over a set of <a class="link" href="class-pygtktreemodelrow.html" title="gtk.TreeModelRow"><code class="classname">gtk.TreeModelRow</code></a>
objects in a <a class="link" href="class-gtktreemodel.html" title="gtk.TreeModel"><code class="classname">gtk.TreeModel</code></a>. A
<a class="link" href="class-pygtktreemodelrowiter.html" title="gtk.TreeModelRowIter"><code class="classname">gtk.TreeModelRowIter</code></a>
is created by calling the Python <code class="function">iter</code>() function on a
<a class="link" href="class-gtktreemodel.html" title="gtk.TreeModel"><code class="classname">gtk.TreeModel</code></a>
object:</p><pre class="programlisting">
treemodelrowiter = iter(treestore)
</pre><p>or, calling the <a class="link" href="class-pygtktreemodelrow.html#method-gtktreemodelrow--iterchildren" title="gtk.TreeModelRow.iterchildren"><code class="methodname">gtk.TreeModelRow.iterchildren</code>()</a>

. When there are no rows left the StopIteration exception is raised. Note
that a <a class="link" href="class-pygtktreemodelrowiter.html" title="gtk.TreeModelRowIter"><code class="classname">gtk.TreeModelRowIter</code></a>
does not iterate over the child rows of the rows it is iterating
over. You'll have to use the <a class="link" href="class-pygtktreemodelrow.html#method-gtktreemodelrow--iterchildren" title="gtk.TreeModelRow.iterchildren"><code class="methodname">gtk.TreeModelRow.iterchildren</code>()</a>
