Doxygen enum in namespace

Question

i'm writing documentation oh this code:

    namespace A {

    enum ENUM 
    {
        /// \var step to frame
        ENUM_1  = 0,            //!< val1
        ENUM_1  = 1,            //!< val2
        ENUM_2 = 2          //!< val3
    };

}

in result, comments values of ENUM don't displayed.

When i remove the namespace, everything is good, but no now

Answer 1

You have to use this format:

    namespace A {
            /*!
            *  \addtogroup A
            *  @{
            */

            /// step to frame
            enum ENUM 
            {
                    ENUM_1  = 0,            //!< val1
                    ENUM_1  = 1,            //!< val2
                    ENUM_2 = 2          //!< val3
            };

            /*! @} */

    }

Answer 2

You are placing the enum document header in the from place, it should be directly above the enum definition:

/// \brief Step to frame
enum ENUM
{
    ...
};
