class CHIProjectData : public QObject
{
public:
    CHIProjectData();
    CHIProjectData(QMap<QString,QString> aProjectData,
                   CHIAkmMetaData* apAkmMetaData = 0,
                   QObject* parent = 0);
private:
    QMap <QString,QString> m_strProjectData;
    CHIAkmMetaData* m_pAkmMetaData;
};

CHIProjectData::CHIProjectData(QMap<QString,QString> aProjectData,
                               CHIAkmMetaData* apAkmMetaData,
                               QObject* aParent)
    :
    QObject(aParent)
{
        m_strProjectData = aProjectData;
        m_pAkmMetaData = apAkmMetaData;
}

为什么它会让"'QObject :: QObject'无法访问类'QObject'中声明的私有成员"错误？
