how to document classes and member functions?

[jackal]

I'm having problems with writing documentations for my classes and their member functions. I've found what I want in Qt base classes. Here are several rows from "QVector.cpp":

/*!
    \class QVector
    \brief The QVector class is a template class that provides a dynamic array.
 
    \ingroup tools
    \ingroup shared
 
    \reentrant
 
    QVector\<T\> is one of Qt's generic \l{container classes}. It
    stores its items in adjacent memory locations and provides fast
    index-based access.
 
    QList\<T\>, QLinkedList\<T\>, and QVarLengthArray\<T\> provide
    similar functionality. Here's an overview:
 
    \list
    \i For most purposes, QList is the right class to use. Operations
       like prepend() and insert() are usually faster than with
	..........
*/
 
/*!
    \fn QVector<T> QVector::mid(int pos, int length = -1) const
 
    Returns a vector whose elements are copied from this vector....
    .........
*/
// ....

When I'm trying to do the same in my ".cpp" files, nothing happens (hovering the functions' calls in other files doesn't show my documentation). I tried to find some documentation about this and the keywords (tags) as well (like "\class", "\brief", "\ingroup"...), but I couldn't find anything. Can anyone help or give any links to documentation concerning this?
