Hello ROOTers, I am trying to derive a class (Aphotclass) from the class which is generated automatically by MakeClass (photclass). My declaration looks like this: class Aphotclass : public photclass { Aphotclass(TTree *tree=0) : photclass(tree) {}; ~Aphotclass() {}; //Int_t Cut(Int_t entry); // I dont want to change these //Int_t GetEntry(Int_t entry); //Int_t LoadTree(Int_t entry); //void Init(TTree *tree); void Loop(); // This is what I want to overwrite //Bool_t Notify(); //void Show(Int_t entry = -1); }; Under ROOT I get: root [1] .L Aphotclass.C root [2] Aphotclass m; Error: can not call private or protected function FILE:(tmpfile) LINE:1 Aphotclass.h 18 Aphotclass Aphotclass::Aphotclass(TTree*); Calling : Aphotclass::Aphotclass(); Match rank: file line signature * 0 Aphotclass.h 18 Aphotclass Aphotclass::Aphotclass(TTree*); *** Interpreter error recovered *** root [3] There seems to be a problem with the constructor. I would be very glad if somebody could help me to get this runnig. Thanks, Claus
