Re: [ROOT] TF with dict

Hi Matthieu,

I should write a FAQ with this type of question.

No, it is not possible to specify a class member function
in the TF1,TF2, etc constructors in the current version.
An interface via the CINT dictionary could be implemented
if your class has been processed via rootcint.
I am not sure if this feature could be implemented with the
existing TF1,2 constructors.
