'QObject :: QObject'不能访问在'QObject'类中声明的私有成员， [英] 'QObject::QObject' cannot access private member declared in class 'QObject'

问题描述

  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 
 {
 m_strProjectData = aProjectData; 
 m_pAkmMetaData = apAkmMetaData; 
} 
  

为什么它给'QObject :: QObject'在类'QObject'中声明的错误？

解决方案

向CHIProjectData类添加一个复制构造函数。 b $ b

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;
}

Why does it give the "'QObject::QObject' cannot access private member declared in class 'QObject'" error?

解决方案

Adding a copy constructor to CHIProjectData class did the trick.
