Strong Type generic Composite class

Hi,
I tried to code a -> Strong typed generic composite class ...
i want to generalize the <function call> and the <interface> that the
compositor will implement
I tried writing it in many variations but none was suffice, or
working.
Any idea what should I look for?

Maybe a pseudo code will help explain:

//Pseudo code

template <class T , Function FunctinName>
class IComposite
{
void addnewItem(T* newItem) { m_list.push_back(newItem); } //
This line problematic too
void IterateThrough()
{
  for (m_list::iterator iDx = m_list.begin;iDx != m_list.end(); iDx++)
   {
      (*iDx)->FunctionName(); //This line is the
main problem
   }
}
vector<T*> m_list;
}

class ICommand
{
   virtual void work() = 0;
};

class worker : public ICommand
{
   void work(){ cout << "BLA" << endl; }
};
class CommandComposite : public ICommand , public IComposite
<ICommand*,ICommand::*work>
{
 void work()
           {
                 IterateThrough();
           }
};

Thanks
