Hello

I'm creating an winForm as TBaseWinForm. Then i'm creating an child of it as 
TBaseGridWinForm with an Grid on it.
I'm adding class procedure on TBaseWinForm as CreateShow as
with TBaseWinForm.Create do
 begin
  Show;
 end


When i call TBaseGridWinForm.CreateShow i saw only TBaseWinForm.
Ok lat's say this happens becouse of  "TBaseWinForm.Create". But when i try 
classic delphi
call : With Self.Create do and etc than i get an compile error as : 
"Potentially polymorphic constructor calls must be virtual"


Any ideas ???

Thanks Dimitris
