|
|
*
|
|
* The view properties are automatically stored inside
|
|
* the directory as hidden file called '.dolphinview'. To read out the view properties
|
|
* just construct an instance by passing the URL of the directory:
|
|
* \code
|
|
* ViewProperties props(KURL("/home/peter/Documents"));
|
|
* const DolphinView::Mode mode = props.viewMode();
|
|
* const bool showHiddenFiles = props.isShowHiddenFilesEnabled();
|
|
* \endcode
|
|
* When modifying a view property, the '.dolphinview' file is automatically updated
|
|
* inside the destructor.
