Hi Réne,
I'm trying to use TTreeFormula, but i'm having some problems.
I have this piece of code:
TFile *f=new TFile("Event.root");
TTree *mytree=(TTree*)f->Get("T");
Event *event=new Event();
TBranch *b = mytree->GetBranch("event");
b->SetAddress(&event);
TTreeFormula *formule=new TTreeFormula("formule","bx<100",mytree);
And i obtain the following message:
Error: Can't call TTreeFormula::TTreeFormula("formule","bx<100",mytree) in
current scope FILE:/tmp/file73vnV4_cint LINE:1
Possible candidates are...
filename line:size busy function type and name (in TTreeFormula)
*** Interpreter error recovered ***
I don't understand because the TFormula constructor is:
TTreeFormula(char* name, char* expression, TTree* tree)
Best Regards
Nuno Almeida
