<p>The iterator will walk the items in a pre-order traversal order, thus visiting the parent node <i>before</i> it continues to the child nodes.</p>
<p>For example, the following code examples each item in a tree, checking the text in the first column against a user-specified search string:</p>
<pre>     QTreeWidgetItemIterator it(treeWidget);
     while (*it) {
         if ((*it)-&gt;text(0) == itemText)
             (*it)-&gt;setSelected(true);
         ++it;
     }</pre>
<p>It is also possible to filter out certain types of node by passing certain <a href="qtreewidgetitemiterator.html#IteratorFlag-enum">flags</a> to the constructor of QTreeWidgetItemIterator.</p>
<p>See also <a href="qtreewidget.html">QTreeWidget</a>, <a href="model-view-programming.html">Model/View Programming</a>, and <a href="qtreewidgetitem.html">QTreeWidgetItem</a>.</p>
<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="IteratorFlag-enum" />QTreeWidgetItemIterator.IteratorFlag</h3><p>These flags can be passed to a <a href="qtreewidgetitemiterator.html">QTreeWidgetItemIterator</a> constructor (OR-ed together if more than one is used), so that the iterator will only iterate over items that match the given flags.</p>
