Hello,
I think you can do 

void MyTTree::Print() {
    cout << " Printing the Tree content..." << endl;
    TTree::Print();
}
> How can I do it. Or... in which part of the User Guide I can read it?

It is not ROOT feature it is C++ property.

Best regards
                   Valeri

Subject: [ROOT] To inherit a Class

Hello:

I would like to create a class named MyTTree

class MyTTree : public TTree {
...
}

and I would like to override the Print() method.
For example, if I have a object

MyTTree *T

I want, if I issue

T->Print()

show a text line in the screen ("followed 
by the standard output of the TTree::Print() method.
How can I do it. Or... in which part of the User Guide I can read it?

Thank you very much in advance for your help.
