object represents a row 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-pygtktreemodelrow.html" title="gtk.TreeModelRow"><code class="classname">gtk.TreeModelRow</code></a>
is created by taking the mapping of a <a class="link" href="class-gtktreemodel.html" title="gtk.TreeModel"><code class="classname">gtk.TreeModel</code></a>. For
example:</p><pre class="programlisting">
treemodelrow = liststore[0]
treemodelrow = liststore[(0,)]
treemodelrow = liststore['0']
</pre><p>all create a <a class="link" href="class-pygtktreemodelrow.html" title="gtk.TreeModelRow"><code class="classname">gtk.TreeModelRow</code></a>
for the first row in <em class="parameter"><code>liststore</code></em>. The <a class="link" href="class-pygtktreemodelrow.html" title="gtk.TreeModelRow"><code class="classname">gtk.TreeModelRow</code></a>
implements some of the Python sequence protocol that makes the row behave
like a sequence of objects. Specifically a tree model row has the capability
of:</p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem">getting and setting column values,</li><li class="listitem">returning a tuple or list containing the column values,
and</li><li class="listitem">getting the number of values in the row i.e. the number of
columns</li></ul></div><p>For example to get and set the value in the second column of a
row, you could do the following:</p><pre class="programlisting">
value = treemodelrow[1]
treemodelrow[1] = value
</pre><p>You can use the Python <code class="function">len</code>() function to get
the number of columns in the row and you can retrieve all the column values
as a list (tuple) using the Python <code class="function">list</code>()
(<code class="function">tuple</code>()) function.</p><p>The <a class="link" href="class-pygtktreemodelrow.html" title="gtk.TreeModelRow"><code class="classname">gtk.TreeModelRow</code></a>
supports one method: the <a class="link" href="class-pygtktreemodelrow.html#method-gtktreemodelrow--iterchildren" title="gtk.TreeModelRow.iterchildren"><code class="methodname">iterchildren</code>()</a>
method that returns a <a class="link" href="class-pygtktreemodelrowiter.html" title="gtk.TreeModelRowIter"><code class="classname">gtk.TreeModelRowIter</code></a>
