Hi Greg,
With TTree::Draw, you can draw directly attributes if an attribute
has its own branch/leaf. THis is the case for TClonesArray.
You can also do t.Draw("event.Function(par....)")
where event is for example the name of your top level branch.
You should be able to call any member function of event.
