AcRxObject:很少重写的函数
自定义类很少重写以下函数: virtual AcRxObject* clone() const; virtual Acad::ErrorStatus copyFrom(const AcRxObject* pSrc); // Do not override; AcDbObject behavior is already accounted for. // virtual HRESULT __stdcall QueryInterface ( REFIID riid, void ** ppvObject ); virtual ULONG __stdcall AddRef(); virtual ULONG __stdcall Release(); 父主题: |
