If I get it right, using the Objects property is analog to what I intended to do with a TStringList for names // to a TFPList for values. > However, it does not actually implement this; it just provides a common > API for a string list with associated objects. > > TStringList actually implements - in a simplistic way - the functionality > to store the strings, and the associated objects. All right, now I get it. Just a point about doc: Some methods implemented in TStringList, but virtual in TString, are listed in the interface of TStringList at http://www.freepascal.org/docs-html/rtl/classes/tstringlist.html. But the ones dealings with associated objects aren't listed there (including the Objects property). This feature is also not mentionned in the description. So, I thought TStringList simply does not implement this functionality. Another point: in the description of TList and TFPList is written that the notification system (not implemented on TFPList) is slows down some mechanisms. Is there a version of TStringList without this feature. I need the simplest and most efficient version, because the type I'm now designing will be the elementary building block of a rather big system.
