Danke für die schnelle Antwort.
Leider bekomme ich immer Exception beim Aufruf...

Code Mainform:

Delphi-Quellcode:

unit mTest;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, Menus, StdCtrls;

type
  TMainform = class(TForm)
    Button1: TButton;
    Button2: TButton;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Mainform: TMainform;

implementation

uses mTest2;

{$R *.dfm}

procedure TMainform.Button1Click(Sender: TObject);
var pr1 : TEditor;
begin

pr1 := TEditor.Create(self);
pr1.ShowModal;
pr1.Free;
end;

procedure TMainform.Button2Click(Sender: TObject);
begin
ShowMessage('Blub!');
end;

end.

Code Editor-Form:

Delphi-Quellcode:

unit mTest2;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TEditor = class(TForm)
    Memo1: TMemo;
    Button1: TButton;
    procedure FormClose(Sender: TObject; var Action: TCloseAction);
    procedure Button1Click(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Editor: TEditor;

implementation

{$R *.dfm}

procedure TEditor.FormClose(Sender: TObject; var Action: TCloseAction);
begin
Action:= caFree;
end;

procedure TEditor.Button1Click(Sender: TObject);
begin
Close;
end;

end.

Formstyle "Mainform" = fsMidForm
Formstyle "Editor" = fsMidChild

Hinweis:
Unter "Proejekt" -> "Optionen" -> "Formulare" befindet sich "Editor" auf der rechten Seite, wird also nicht autom. mitgeladen - was auch sein soll.
