Then you must reimplement this class's <a href="#previewUrl">previewUrl</a>() function, which is called by the file dialog if the preview of a file (specified as a URL) should be shown. <p> See also <a href="ntqfiledialog.html#setPreviewMode">TQFileDialog::setPreviewMode</a>(), <a href="ntqfiledialog.html#setContentsPreview">TQFileDialog::setContentsPreview</a>(), <a href="ntqfiledialog.html#setInfoPreview">TQFileDialog::setInfoPreview</a>(), <a href="ntqfiledialog.html#setInfoPreviewEnabled">TQFileDialog::setInfoPreviewEnabled</a>(), <a href="ntqfiledialog.html#setContentsPreviewEnabled">TQFileDialog::setContentsPreviewEnabled</a>(). <p> For an example of a preview widget see qt/examples/qdir/qdir.cpp. <p>See also <a href="misc.html">Miscellaneous Classes</a>. <hr><h2>Member Function Documentation</h2> <h3 class=fn><a name="TQFilePreview"></a>TQFilePreview::TQFilePreview () </h3> Constructs the TQFilePreview. <h3 class=fn>void <a name="previewUrl"></a>TQFilePreview::previewUrl ( const <a href="ntqurl.html">TQUrl</a> & url )<tt> [pure virtual]</tt> </h3> <p> This function is called by <a href="ntqfiledialog.html">TQFileDialog</a> if a preview for the <em>url</em> should be shown.
