Consider the following project

foo.h

/*!
 * \namespace Foo
 * A namespace
 * \inmodule Foo
 */
namespace Foo {
    /*!
     * does stuff
     */
    void doStuff();
} 

bar.h

namespace Foo {
    /*!
     * \class Foo::Bar
     * \inmodule Foo
     */
    class Bar {
    };

    /*!
     * Create a Bar
     */
    Bar createBar();
} 

foo.qdoc

/*!
    \module Foo
    \title Foo C++ Classes
    \brief Stuff.
*/ 

foo.qdocconf

project = Foo
description = Stuff
documentationinheaders = true
headerdirs = .
sourcedirs = . 

This will create two main pages, foo.html and bar.html

foo.html will show the namespace and the two functions doSomething() and createBar(). It also says to #include <Foo> to use createBar().

However createBar actually needs #include <Bar>, and it much more closely associated with the Bar class. Therefore I want it to be part of bar.html instead.

To achieve that I tried to add "\relates Foo::Bar" to createBar(), but that doesn't change anything. And neither does "\inheaderfile Bar"
