  18  * @brief Maintains the view properties like 'view mode' or
  19  *        'show hidden files' for a directory.
  20  *
  21  * The view properties are automatically stored as part of the file
  22  * .directory inside the corresponding path. To read out the view properties
  23  * just construct an instance by passing the path of the directory:
  24  *
  25  * \code
  26  * ViewProperties props(QUrl::fromLocalFile("/home/peter/Documents"));
  27  * const DolphinView::Mode mode = props.viewMode();
  28  * const bool hiddenFilesShown = props.hiddenFilesShown();
  29  * \endcode
  30  *
  31  * When modifying a view property, the '.directory' file is automatically updated
  32  * inside the destructor.
  33  *
  34  * If no .directory file is available or the global view mode is turned on
  35  * (see GeneralSettings::globalViewMode()), the values from the global .directory file
  36  * are used for initialization.
