User interface > Translation options > Other compiler > runtime class information
In the Microsoft Foundation Classes (MFC) the macros DECLARE_DYNAMIC and IMPLEMENT_DYNAMIC give access to runtime class information, similar to the runtime information that is provided in the VCL by the accordingly overwritten functions of TObject or by TD2CObject. If you need runtime information and don't like to use TD2CObject, you can activate the insertion of these macros in the options dialog at the page Other compiler.
The macros can be renamed by means of the substitution table of the translator. An obvious alternative would be to use the macros "DECLARE_DYNCREATE" and "IMPLEMENT_DYNCREATE" also defined for the MFC in the file "afx.h".
The following table compares the class names and functions of the MFC and Delphi:
class CObject |
class TObject |
struct CRuntimeClass |
class TMetaClass |
CObject::GetRuntimeClass |
TObject::ClassType |
CRuntimeClass::IsDerivedFrom |
TMetaClass::InheritsFrom |
CObject::IsKindOf |
TObject::InheritsFrom |
CRuntimeClass::CreateObject |
TMetaClass::Create |
CObject::CreateObject |
TObject::Create |
