<!-- $$$QFileSystemModel-description -->
<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qfilesystemmodel.html">QFileSystemModel</a> class provides a data model for the local filesystem.</p>
<p>This class provides access to the local filesystem, providing functions for renaming and removing files and directories, and for creating new directories. In the simplest case, it can be used with a suitable display widget as part of a browser or filter.</p>
<p><a href="qfilesystemmodel.html">QFileSystemModel</a> can be accessed using the standard interface provided by <a href="../qtcore/qabstractitemmodel.html">QAbstractItemModel</a>, but it also provides some convenience functions that are specific to a directory model. The <a href="qfilesystemmodel.html#fileInfo">fileInfo</a>(), <a href="qfilesystemmodel.html#isDir">isDir</a>(), <a href="qfilesystemmodel.html#fileName">fileName</a>() and <a href="qfilesystemmodel.html#filePath">filePath</a>() functions provide information about the underlying files and directories related to items in the model. Directories can be created and removed using <a href="qfilesystemmodel.html#mkdir">mkdir</a>(), <a href="qfilesystemmodel.html#rmdir">rmdir</a>().</p>
<p><b>Note: </b><a href="qfilesystemmodel.html">QFileSystemModel</a> requires an instance of <a href="qapplication.html">QApplication</a>.</p><a name="example-usage"></a>
<h3 >Example Usage</h3>
<p>A directory model that displays the contents of a default directory is usually constructed with a parent object:</p>
<pre class="cpp">
<span class="type"><a href="qfilesystemmodel.html#QFileSystemModel">QFileSystemModel</a></span> <span class="operator">*</span>model <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qfilesystemmodel.html#QFileSystemModel">QFileSystemModel</a></span>;
model<span class="operator">-</span><span class="operator">></span>setRootPath(<span class="type"><a href="../qtcore/qdir.html">QDir</a></span><span class="operator">::</span>currentPath());
</pre>
<p>A tree view can be used to display the contents of the model</p>
<pre class="cpp">
<span class="type"><a href="qtreeview.html">QTreeView</a></span> <span class="operator">*</span>tree <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qtreeview.html">QTreeView</a></span>(splitter);
tree<span class="operator">-</span><span class="operator">></span>setModel(model);
</pre>
<p>and the contents of a particular directory can be displayed by setting the tree view's root index:</p>
<pre class="cpp">
tree<span class="operator">-</span><span class="operator">></span>setRootIndex(model<span class="operator">-</span><span class="operator">></span>index(<span class="type"><a href="../qtcore/qdir.html">QDir</a></span><span class="operator">::</span>currentPath()));
</pre>
<p>The view's root index can be used to control how much of a hierarchical model is displayed. <a href="qfilesystemmodel.html">QFileSystemModel</a> provides a convenience function that returns a suitable model index for a path to a directory within the model.</p>
<a name="caching-and-performance"></a>
<h3 >Caching and Performance</h3>
<p><a href="qfilesystemmodel.html">QFileSystemModel</a> will not fetch any files or directories until <a href="qfilesystemmodel.html#setRootPath">setRootPath</a>() is called. This will prevent any unnecessary querying on the file system until that point such as listing the drives on Windows.</p>
<p>Unlike QDirModel, <a href="qfilesystemmodel.html">QFileSystemModel</a> uses a separate thread to populate itself so it will not cause the main thread to hang as the file system is being queried. Calls to <a href="qfilesystemmodel.html#rowCount">rowCount</a>() will return 0 until the model populates a directory.</p>
<p><a href="qfilesystemmodel.html">QFileSystemModel</a> keeps a cache with file information. The cache is automatically kept up to date using the <a href="../qtcore/qfilesystemwatcher.html">QFileSystemWatcher</a>.</p>
