Question

I use Borland C++ Builder.

And i had o problem

#include <Classes.hpp>
class TMyObject : public TObject
{
   __fastcall TMyObject();
   __fastcall ~TMyObject();//I would like to inherite my destructor from TObject
};

__fastcall TMyObject::TMyObject() : TObject()//it will inherited my constructor from TObject
{
}

And for that new destructor that will inherite ~TObject?

__fastcall TMyObject::~TMyObject?????????????

Answer 1

This can be solved at TObject‘s level. Its destructor has to be virtual:

#include <Classes.hpp>
class TObject 
{
   __fastcall TObject();
   virtual __fastcall ~TObject(); 
};

This way you can either do:

TObject * pobj = new TMyObject();
delete pobj;

or

TMyObject * pobj = new TMyObject();
delete pobj;

Both destructors will be called (~TMyObject() first and then ~TObject()) and you will have no leak.
