Hello rooters, I want to order some objects in a list, like: TList *list = new TList; TEllipse *ell = new TEllipse; TLine *lin = new TLine; list->Add(ell); list->Add(lin); Now I want to write this list of objects to a root file, like: TFile f1("test.root", "RECREATE"); TTree *t = new TTree("List", "My List"); t->Branch("TList", "TList", &list, 32000, 9); t->Fill(); f1.Write(); f1.Close(); And read the list again, like: TFile f2("test.root", "READ"); t = (TTree*)f2.Get("List"); t->GetBranch("TList")->SetAddress(&list); t->GetEntry(0); list->Print(); But this fails (as I understand, because of ClassDef(TSeqCollection, 0)). Is there a way to write such a list and get it back as one entry? The idea is to have a list which stores several objects describing a program setup (like the gui elements above, which are describing a graphical setup). I want to be able to store and read this setup with a single expression. Thanks alot, Thomas.
