<hr><h2><a name="details"></a>Detailed Description</h2>
Abstract preview widget for the <a href="qfiledialog.html">QFileDialog</a>
<p>
This class is an abstract base class which is used for implementing
widgets which can display a preview of a file in the QFileDialog.
<p>If you want to do that you have to derive your preview widget
from any <a href="qwidget.html">QWidget</a> and from this class. Then you have to reimplement
the <a href="#ac8b04">previewUrl</a>() method of this class which is called by the filedialog
if the preview of an URL should be shown.
<p>See also <a href="qfiledialog.html#718b9e">QFileDialog::setPreviewMode</a>(), <a href="qfiledialog.html#d11578">QFileDialog::setContentsPreview</a>(),
<a href="qfiledialog.html#53e86c">QFileDialog::setInfoPreview</a>(), <a href="qfiledialog.html#57f538">QFileDialog::setInfoPreviewEnabled</a>(),
<a href="qfiledialog.html#9b6ece">QFileDialog::setContentsPreviewEnabled</a>().
<p>For an example documentation of a preview widget look at the example
qt/examples/qdir/qdir.cpp.
<hr><h2>Member Function Documentation</h2>
<h3 class="fn"><a name="51ad50"></a>QFilePreview::QFilePreview()</h3>
<p>Constructor. Does nothing.
<h3 class="fn">void<a name="ac8b04"></a>QFilePreview::previewUrl(const<a href="qurl.html">QUrl</a>&url) <code>[virtual]</code></h3>
<p>This method is called by <a href="qfiledialog.html">QFileDialog</a> if a preview
for the <em>url</em> should be shown. Reimplement this
method to do file/URL previews.
