I'm not sure of reasons why trolltech uses struct. May be because they
have not to specify access specifiers, or may be because they want to
explicitly look private classes in another way for source structural
reasons, or its simply historical.

But I know, it's not because it gives fewer symbols in the final
lib. Class and struct are the same besides that the default for access
is public: in struct and private: in class. The choice of one or the other
is mostly a personal one. (Well, use struct{} for things with many data
members but few methods, class{} for all other ones, is a good rule
though)


Ciao,
Michael.
