Proxy classes

[Jonas Cord]

What is the use of proxy classes? From what I understand they are used
to hide the implementation details of a class. But can't you obtain
exactly the same results by splitting the class definition and
implementation between a .H file and a .CPP file?
Thanks,

Jonas

No, because even the private parts of a class definition need to
be declared in the .H file. Even if they weren't the size of
the object would have to be exposed somehow. Hence anybody
who uses the public interface (the .h file) would have to
recompile/change when any internal changes.
