Hi,
I am starting to play with Trees and Branches, so I decided to
have a look at the 'How to' documentation, in particular at 'How to Create
and Fill a Tree'. I follow the example but replaced Event with MyEvent
(which inherits from TObject). When I try to run my small macro I get:
Error in <TTree::BranchObject>: Cannot find class:MyEvent
but if I do '.class MyEvent' I can perfectly see it (this is in a shared
library produced together with the corresponding dictionary, etc...).
The offending lines look like:
MyEvent* myevent = 0;
tree->Branch("myevent","MyEvent", &myevent, bsize,split);
After going up and down and consulting some expert (Ivana) we removed the
first string in the second line, therefore becaming:
tree->Branch("MyEvent", &myevent, bsize,split);
and... it works!!!
The question now is wether this is correct or not. If it *is* correct
then, could you please correct the web documentation accordingly?... If
not, could you give me any solution?...
Thanks on advance,
Isidro
