Hello, I have two questions concerning subclasses in a TBranch. If I have a pointer to a subclass, like ClassB * class_b; (in a ClassA.h) and fill a tree with a Branch "ClassA", the class_b does not appear as a folder, even though I defined: Bool_t IsFolder() {return kTRUE;} (this has been suggested in a Mail "Re: Can't browse sub objects" 1997 oct) the data write and re-read works fine, but it would be very nice if one is able to browse a complete event like I saw this in the web-page of the atlas simulation programm. The second question is more important for me. If I define an array of subclasses in ClassA.h, like ClassB class_b[5]; it is not able to get the data from this array: Warning in <TTree::Branch>: Cannot process member:class_b[5] But it would be difficult for me to switch to TClonesArray (like it is done in the Event example). Does anybody know a workaround? Or did I made something wrong? Thanks for your help & best regards, Ingo Froehlich -- Ingo Froehlich, II.
