This can for - example be used as default destination for newly created object managed - by a certain Resource family. - - Activation of Resources can be covered by a two step process of being opened - and then loaded. Deactivation corresponds to saving and closing. - - Different application ususally share the same set of Resources. - - The Resource base class provides the management functionality. Classes - inheriting from Resource automatically appear in the general kresources - kcontrol module. - - Concrete functionality of Resources is specified per family by a subclass of - Resource. This classes in turn have subclasses which implement the different - flavours of the functionality represented by the family. - - A subclass should reimplement at least the constructor and the - writeConfig method. - - An example for a Resource subclass hierarchy would be the "calendar" family. - The ResourceCalendar subclass would specify an API for accessing calendar - data. Subclasses of ResourceCalendar would implement this API for local files, - remote files, specific calendar servers etc. -*/ -class KRESOURCES_EXPORT Resource : public TQObject -{ - friend class Factory; - friend class ManagerImpl; - - Q_OBJECT - public: - typedef TQValueList<Resource *> List; - - /** - * Constructor.
