Globale Checkbox

[Luckie]

Formular 1:

Delphi-Quellcode:

procedure TForm1.Button1Click(Sender: TObject);
begin
  Form2.ShowModal;
  if Form2.IsChecked then
    Caption := 'Ist angehakt'
  else
    Caption := 'Ist nicht angehakt';
end;

Formular 2:

Delphi-Quellcode:

unit Unit2;

interface

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

type
  TForm2 = class(TForm)
    CheckBox1: TCheckBox;
    procedure CheckBox1Click(Sender: TObject);
  private
    { Private-Deklarationen }
    FIsChecked: Boolean;
  public
    { Public-Deklarationen }
    property IsChecked: Boolean read FIsChecked write FIsChecked;
  end;

var
  Form2: TForm2;

implementation

{$R *.dfm}

procedure TForm2.CheckBox1Click(Sender: TObject);
begin
  IsChecked := CheckBox1.Checked;
end;

end.

Voraussetzung ist, dass Formular 2 beim Start automatisch erzeugt wird.
