<h4>Parameters</h4>
<p>No arguments.</p>
<h4>Return Type</h4>
<p><code class="type">void</code></p>
<h3><a name="updateRow"></a>updateRow</h3>
<p>Updates the row of the tree node. This allows the tree to redraw
 only the current tree item row (the children are not redrawn).
 This is useful when only a few items have changed and therefore
 the whole data of the tree does not need to be redrawn.</p>
<h4>Syntax</h4>
<pre class="method-syntax">object.updateRow()</pre>
<h4>Parameters</h4>
