Title: TfrDataManager abstract methods
Post by: Borneq on May 21, 2022, 08:20:57 am

Lazreport is based on FreeReport. I am currently translate FreeReport binary frf files <-> xml files.
Is part of TfrDataManager

Code: Pascal  [Select][+][-]

1.     else if b = $FD then // datasets
2.     begin
3.       if frDataManager <> nil then
4.         frDataManager.LoadFromStream(Stream);
5.       break;
6.     end

Is always nil, but frf binary files have this data.
LoadFromStream,SaveToStream and LazReport's LoadFromXML,SaveToXML are abstract and I don't found class derived from TfrDataManager. Where is code ot this four methods?
