-Use the StoredValues property to specify property names cannot be assigned -using the Object Inspector; this may be needed for properties which cannot be -represented as a singular value or does not have published visibility.

It can be +used for properties which cannot be represented as a singular value or do not +have published visibility. Use the OnSaveProperties and OnRestoreProperties +event handlers to store or restore (respectively) the values for these items in +StoredValues. +
++The class can alo be used to save and restore properties for TFrame instances +on a form, but it requires some additional coding. The RootNodePath must be +specified to identify the path where the TFrame values are stored. In addition, +the SessionProperties for the frame must be assigned in an overridden +constructor and the Restore method must be called to reload the values. The +Save method method also be called in na overridden Destructor for the frame.

+Use TINIPropStorage or TJsonPropStorage components to save and restore session +properties using either a .INI file or a JSON (JavaScript Object Notation) file. +
-Defaults to the application name with a '.xml' extension if no value is -specified in the property. +A default file name derived from the application name is used if no value is +specified in the property. For Windows, the file has an '.xml' extension, and +is stored in the same directory as the application executable. For example: +'PROGRAMNAME.XML'. For Linux, the file (with a leading '.' and without an +extension) is stored in the home directory for the current user. For example: +'.PROGRAMNAME'.
Provides the name path to the XML node where the property values are stored in -FileName. +FileName. It overrides the inherited RootSection value when provided, and +determines the DOM node where property values are stored in the SaveProperties +method. +
++If the class is used for session properties on a TFrame instance, RootNodePath +must be specified with a path for the frame instance. For example: +'TApplication/Frame1'.
