Constructors

Constructors start with the keyword "constructor" in Object-Pascal and can have an arbitrary name. In C++ is the name of the of the class also the name of the constructor.

constructor classname.foo;
->   
__fastcall classname::classname ( )

Constructor of the base class

Delphi2Cpp tries to find the call of the constructor of a base class and brings it in C++ form.

constructor foo.Create(Owner: TComponent);
begin                   
  inherited Create(Owner);                                         
end;                                         

->

__fastcall foo::foo ( TComponent * Owner )
: inherited   ( Owner )                   
{                                         
}                                         

Addition of missing constructors

Unlike Delphi constructors of base classes cannot be called directly in C++. A new constructor has to be written in the derived class within which the constructor of the base class is called. Delphi2Cpp inserts missing constructors in C++ automatically, e.g.

inline __fastcall virtual TDerivedComponent(TComponent* Owner) : inherited(Owner) { }
