Hi, is it possible to have a virtual class variable? I want to have a
pointer available per class that can be a different value.
Something like this:
TA = class
class var Foo: TObject; virtual;
end;
TB = class(TA)
class var Foo: TSpecialObject; override;
end;
I have in
My current idea for a solution is here:

Can anyone think of something with less code? I guess I could save a

Regards,
Andrew

The thing you need requires different implementation - something like
storing a virtual class variable in

I would guess that class vars are stored in the vmt already...
No, class var and regular variable has no difference except the scope.
It is a static variable which is shared between all instances and
descendants - so
Ahhh ok I understand now. , Thank you.
