Hi Martin,

You could try:
	TIter next(dir->GetList());
	while( (TObject *obj = next()) ) {
          if (obj->InheritsFrom(TH1::Class()) obj->Write();
       }

Cheers,
Philippe.

Subject: [ROOT] Write all histograms problem



Hello,

In my code I read a ntuple and do the following to write all histograms
(objects);


TDirectory *dir = gDirectory;
TFile *f = new TFile("file.root","recreate");
->Write();
delete f;


The file.root contain all histograms but he contain also the ntuple that I
read...
I don't want to save the ntuple in the file. Writing histogram one by one
works but do you have another solution.

Martin
