Hello,
I have problem in CVS version of root (06 Oct 2004):
TTree *tmp_tree = (TTree*)gDirectory->Get("my_tree");
c1->SetTitle( Form("event: %6i, from file: %s",
tmp_tree->GetReadEntry(), tmp_tree->GetCurrentFile()->GetName()) );
(for example: event = 123, name = "/data/run456.root")
title on Canvas is (in CVS version):
event: 123, from file: (null)
why (null) ???
in pro version (4.00.08) is all OK:
event: 123, from file: /data/run456.root
Thanks,
Jano
