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>QFileSystemModel can be accessed using the standard interface
provided by <a href="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 class="compat" href="qobject-qt3.html#name">name</a>(), and path()
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> QFileSystemModel requires an instance of a GUI
application.</p>
<a id="example-usage" name="example-usage" />
<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">QFileSystemModel</span> <span class="operator">*</span>model <span class="operator">=</span> <span class="keyword">new</span> <span class="type">QFileSystemModel</span>;
model<span class="operator">-</span><span class="operator">></span>setRootPath(<span class="type"><a href="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="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 class="obsolete" href="qdirmodel.html">QDirModel<sup>(obsolete)</sup></a> provides a
convenience function that returns a suitable model index for a path
to a directory within the model.</p>
<a id="caching-and-performance" name="caching-and-performance" />
<h3>Caching and Performance</h3>
<p>QFileSystemModel 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 <a class="obsolete" href="qdirmodel.html">QDirModel<sup>(obsolete)</sup></a>, QFileSystemModel
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>QFileSystemModel keeps a cache with file information. The cache
is automatically kept up to date using the <a href="qfilesystemwatcher.html">QFileSystemWatcher</a>.</p>
