TfrDataManager abstract methods
« 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?
