Hi,

I have 2 objects inherited from the base one

T_A = class(TObject);

T_B1 = class(T_A);
T_B2 = class(T_A);
T_B3 = class(T_A);

Now if I want to extend T_B1 it is easy to inherit it to T_C1 = class (T_B1) 
and add many functions to it, but.

I want the same extend T_B2  not T_B3,

1 - The first idea is adding this functions to T_A, but it is not my class to 
modify it, or it is protected from my modify.
2 - Copy and paste this functions to T_B2, but in that case I need every time 
to fix functions in B1 I must do it in B2, that make it so hard, and not good
programming quality.

Is there any new idea to do that, what about Helper, generics, i read about it 
i felt it is not fit to my problem (or i am wrong).

Maybe you can try interfaces and interface delegation.

Michael.
