Morning,

'inherited' is a Delphi call which lets you call a method in the base class
(or parent class) and you see it a lot in component design where you have to
call, say, the inherited create() function in an over ridden (?) method. So
you might have something like :

MyComponent.OnClick(.....)
begin
inherited;
rest of custom code here ...
...
end;


In C++ there is a trick used (in the BCB5 Developers Guide) which does a
similar thing :

in the .h file defining your class :

class MyClass : public ParentClass {
typedef inherited ParentClass;
...
}

in the .cpp file implementing your class :

void MyClass::DoSomething(stuff....)
{
inherited::DoSomething(stuff.....);
more code here....
}

alternatively, if you are using someone else's class/component definitions
and either don't have the source code, or don't want to change it to add the
typedef, you can simply do this :

void MyClass::DoSomething(stuff....)
{
ParentClass::DoSomething(stuff.....);
more code here....
}

The problem is, in Delphi, you simply say 'inherited' and the parent class'
method is called for you. In C++ you need to know what the parent class is
called before you can call the method.

I would gladly try it if I could understand what is this "Inherited" you are
refering to.
(I'm using BCB, noy Delphi). And so far as I know there are no Inherited
things to call in events.

Maybe small code snippet would help me understand
