Add macro documentation to class documentation, how?

[zack]

I have a macro and this macro is placed in the header of a class.
Now of course I want that this macro also appears at this site where the class documentation is.
Take a look at following Qt documentation:
http://qt-project.org/doc/qt-5.0/qtcore/qmetatype.html#Q_DECLARE_METATYPE
Q_DECLARE_METATYPE is on the same page like the class QMetaType,
how can I do this with doxygen?

At the moment the macro docu appears at the file documentation page, but I want to disable the file documentation, I want to keep the amount of pages for the documentation at minimum (KISS).

Regards.
