Hi,
I tried to code a -Strong typed generic composite class ...

I tried writing it in many variations but none was suffice, or
working.
Any idea what should I look for?

I don't even have an idea what you are trying to accomplish.

This line problematic too
void IterateThrough()

{
(*iDx)->FunctionName(); //This line is the
main problem

And what is the problem?

The above amounts to nothing more than calling a certain member function on
all items in a list of T*. If have no idea why you would call that a
composition class.

Nope. Pseudocode did not help either.
Maybe, if you would show a use case, some piece of possible client code
together with an explanation of the resulting behavior, it might become
more clear what you are after.
