Wie erzeuge ich ein MDI ChildForm2 aus MDI Childform1 per Button or main Menu ?

[nuclearping]

Delphi-Quellcode:

unit ChildForm1;

interface

...

implementation

uses
  ...,
  MainForm;

...

procedure TChildForm1.Button1Click(Sender: TObject);
begin
  YourMainFormClass.MenuNewClick(Self);
end;

So?
