About-Dialog in Komponente

[FriFra]

Ich habe es jetzt hinbekommen

Allerdings funktioniert es nur in Delphi7... Delphi5 und 6 kennen DesignEditors und DesignIntf nicht! Was kann man da tun?

Die Variants ist kein grosses Problem, da man die über entspr. Compilerschalter übergehen kann.

Delphi-Quellcode:

unit GetLocalMail;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls,
  Dialogs, StdCtrls, Registry, IniFiles, ActiveX, ShlObj, shellApi,
  ComCtrls, ComObj, DesignEditors, DesignIntf;

const
  COMP_VERSION = '1.0';

type
  TAboutGetLocalMail = class(TPropertyEditor)
  public
    procedure Edit; override;
    function GetAttributes: TPropertyAttributes; override;
    function GetValue: string; override;
  end;
  TGetLocalMail = class(TComponent)
  private
    { Private-Deklarationen }
    fAbout: TAboutGetLocalMail;
    B_IFN: boolean;
    B_LN: boolean;
    B_OL: boolean;

    procedure GetMail;

    { Protected-Deklarationen }
