Konzeptfrage FormCreate

[Zoot]

So sollte es gehen:

Zitat von WIng2005:

Delphi-Quellcode:

unit Unit1;
interface
uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, ExtCtrls, StdCtrls;
type
  TForm1 = class(TForm)
    Button1: TButton;
    Button2: TButton;
    Panel1: TPanel;
    procedure Button1Click(Sender: TObject);
    function formerzeugen(fclass:TFormClass;var nform : Tform):boolean;
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation
uses unit2;
{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
  formerzeugen(TForm2,TForm(form2));
end;

function TForm1.formerzeugen(fclass:TFormClass;var nform:Tform):boolean;
Begin
    application.CreateForm(fclass,nform);
    nform.show 
end;

end.
