problem in extending QList (a template class)

[Jens Zurheide]

Hi,

I found something interesting about templates for you at
http://www.codeguru.com/cpp/tic/tic0169.shtml There might be more of this 
stuff in the internet.

Should read like this:
template<class T> class Chain : public QList<T> {
Note: public inheritance translates into human language as "is a".

template< class T>
  Chain<T>::Chain()
  {
  }
template< class T>
  Chain<T>::~Chain()
  {
  }

Note, that all member functions' definitions (where you define what the 
member function have to do) must be in header files for template classes.

Have fun,
Jens
