  30  * @brief Maintains the view properties like 'view mode' or
  31  *        'show hidden files' for a directory.
  32  *
  33  * The view properties are automatically stored as part of the file
  34  * .directory inside the corresponding path. To read out the view properties
  35  * just construct an instance by passing the path of the directory:
  36  *
  37  * \code
  38  * ViewProperties props(KUrl("/home/peter/Documents"));
  39  * const DolphinView::Mode mode = props.viewMode();
  40  * const bool showHiddenFiles = props.isShowHiddenFilesEnabled();
  41  * \endcode
  42  *
  43  * When modifying a view property, the '.directory' file is automatically updated
  44  * inside the destructor.
  45  *
  46  * If no .directory file is available or the global view mode is turned on
  47  * (see GeneralSettings::globalViewMode()), the values from the global .directory file
  48  * are used for initialization.
