Code aus Button in andere unit auslagern

[Michael80]

Irgendwie blick ich den Sinn hier net ganz.

wieso nicht einfach

unit1 = Form1 ??

Delphi-Quellcode:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, System.ComponentModel, Borland.Vcl.StdCtrls;

type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation
uses Unit2;
{$R *.nfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
Unit2.Button1Click(Form1);
end;

end.

unit2

Delphi-Quellcode:

procedure Button1Click(Sender: TObject);
implementation
uses Unit1;
procedure Button1Click(Sender: TObject);
begin
   Form1.Color := clred;
end;
end.
