 263
 264     Some classes don't have a well-defined copying semantics. In this case the
 265     standard C++ convention is to not allow copying them. One way of achieving
 266     it is to use this macro which simply defines a private copy constructor and
 267     assignment operator.
 268
 269     Beware that simply not defining copy constructor and assignment operator is
 270     @em not enough as the compiler would provide its own automatically-generated
 271     versions of them -- hence the usefulness of this macro.
 272
 273     Example of use:
 274     @code
 275     class FooWidget
 276     {
 277     public:
 278         FooWidget();
 279         ...
 280
 281     private:
 282         // widgets can't be copied
 283         DECLARE_NO_COPY_CLASS(FooWidget)
 284     };
 285     @endcode
 286
 287     Notice that a semicolon should not be used after this macro and that it
 288     changes the access specifier to private internally so it is better to use
 289     it at the end of the class declaration.
