<div class="descr">
<h2>Detailed Description</h2>
<p>The QStringListModel class provides a model that supplies strings to views.</p>
<p>QStringListModel is an editable model that can be used for simple cases where you need to display a number of strings in a view widget, such as a <a href="qlistview.html">QListView</a> or a <a href="qcombobox.html">QComboBox</a>.</p>
<p>The model provides all the standard functions of an editable model, representing the data in the string list as a model with one column and a number of rows equal to the number of items in the list.</p>
<p>Model indexes corresponding to items are obtained with the <a href="qabstractlistmodel.html#index">index()</a> function, and item flags are obtained with <a href="qstringlistmodel.html#flags">flags</a>(). Item data is read with the <a href="qstringlistmodel.html#data">data</a>() function and written with <a href="qstringlistmodel.html#setData">setData</a>(). The number of rows (and number of items in the string list) can be found with the <a href="qstringlistmodel.html#rowCount">rowCount</a>() function.</p>
<p>The model can be constructed with an existing string list, or strings can be set later with the <a href="qstringlistmodel.html#setStringList">setStringList</a>() convenience function. Strings can also be inserted in the usual way with the <a href="qstringlistmodel.html#insertRows">insertRows</a>() function, and removed with <a href="qstringlistmodel.html#removeRows">removeRows</a>(). The contents of the string list can be retrieved with the <a href="qstringlistmodel.html#stringList">stringList</a>() convenience function.</p>
<p>An example usage of QStringListModel:</p>
<pre class="cpp"> <span class="type">QStringListModel</span> <span class="operator">*</span>model <span class="operator">=</span> <span class="keyword">new</span> <span class="type">QStringListModel</span>();
<span class="type"><a href="qstringlist.html">QStringList</a></span> list;
