/**
 * This widget works as a network transparent filebrowser. You specify a URL
 * to display and this url will be loaded via KDirLister. The user can
 * browse through directories, highlight and select files, delete or rename
 * files.
 *
 * It supports different views, e.g. a detailed view (see KFileDetailView),
 * a simple icon view (see KFileIconView), a combination of two views,
 * separating directories and files ( KCombiView).
 *
 * Additionally, a preview view is available (see KFilePreview), which can
 * show either a simple or detailed view and additionally a preview widget
 * (see setPreviewWidget()). KImageFilePreview is one implementation
 * of a preview widget, that displays previews for all supported filetypes
 * utilizing KIO::PreviewJob.
 *
 * Currently, those classes don't support Drag&Drop out of the box -- there
 * you have to use your own view-classes. You can use some DnD-aware views
 * from Björn Sahlström <bjorn@kbear.org> until they will be integrated
 * into this library. See http://devel-home.kde.org/~pfeiffer/DnD-classes.tar.gz
 *
 * This widget is the one used in the KFileWidget.
 *
 * Basic usage is like this:
 * \code
 *   KDirOperator *op = new KDirOperator(QUrl("file:///home/gis"), this);
 *   // some signals you might be interested in
 *   connect(op, SIGNAL(urlEntered(const QUrl&)),
 *           SLOT(urlEntered(const QUrl&)));
 *   connect(op, SIGNAL(fileHighlighted(const KFileItem &)),
 *           SLOT(fileHighlighted(const KFileItem &)));
 *   connect(op, SIGNAL(fileSelected(const KFileItem &)),
 *           SLOT(fileSelected(const KFileItem &)));
 *   connect(op, SIGNAL(finishedLoading()),
 *           SLOT(slotLoadingFinished()));
 *
 *   KConfigGroup grp(KSharedConfig::openConfig(),"Your KDiroperator ConfigGroup" );
 *   op->readConfig( &grp);
 *   op->setView(KFile::Default);
 * \endcode
 *
 * This will create a childwidget of 'this' showing the directory contents
 * of /home/gis in the default-view. The view is determined by the readConfig()
 * call, which will read the KDirOperator settings, the user left your program
 * with (and which you saved with op->writeConfig()).
 *
 * @short A widget for displaying files and browsing directories.
