 /**
  * @class KDirOperator kdiroperator.h <KDirOperator>
  *
  * 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.

           *
           * Now, how does this logic work. It will get the first element on the list (with no filename),
           * following the previous example say "/home/foo" and set it as the top most url.
           *
           * After this, it will iterate over the rest of items and check if this URL (topmost url)
           * contains the url being iterated.
           *
           * As you might have guessed it will do "/home/foo" against "/boot/grub" (again stripping
           * filename), and a false will be returned. Then we upUrl the top most url, resulting in
           * "/home" against "/boot/grub", what will again return false, so we upUrl again. Now we
           * have "/" against "/boot/grub", what returns true for us, so we can say that the closest
           * common ancestor of both is "/".
