Description
TIniPropStorage is a
TCustomIniPropStorage descendant
which implements the class used to store form session properties to a file
using the INI format. It sets the visibility for properties and methods
introduced in ancestor classes.
Use the SessionPropperties property in the TForm or a TFrame instance which owns the class to define the components and property names stored using the storage mechanism.
Use IniFileName to specify the path and file name where session properties are stored in IniFile.
Use IniSection to specify the name for a section where session properties are stored. When omitted, session properties are stored at the root section level in IniFile.
Use Active to enable or disable read/write access to the INI file storage for the class instance.
Use the event handlers in the class to perform actions needed before or during save and restore operations using the session properties.
