TButton ohne Fokus

[uwewo]

Eigentlich brauchst Du dann nur einen Button, man muss nur wissen welches Edit zuletzt den Focus hatte.

Hab da mal was ausprobiert

Delphi-Quellcode:

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    Edit1: TEdit;
    Edit2: TEdit;
    Edit3: TEdit;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  private
    { Private-Deklarationen }
    Active, Previous : TWinControl;
  public
    { Public-Deklarationen }
     procedure ControlChanged(Sender: TObject);
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.ControlChanged(Sender: TObject);
begin
   Previous := Active;
   Active := Form1.ActiveControl;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
   Screen.OnActiveControlChange := ControlChanged;
end;

procedure TForm1.Button1Click(Sender: TObject) ;
begin
   if TEdit(Previous) = Edit1 then ShowMessage('Edit1 hatte den Focus');
   if TEdit(Previous) = Edit2 then ShowMessage('Edit2 hatte den Focus');
   if TEdit(Previous) = Edit3 then ShowMessage('Edit3 hatte den Focus');
end;

end.

Vergiss nicht ControlChanged freizugeben.
