Integer in ListItem eines ListViews speichern

[DennisHB]

MÖP es geht - nu auch getestet - n Pointer is doch nix anderes als ne Zahl (Integer? evtl Unsigned?)
Man kann ja auch Objecte an ein xyz.Tag hängen (eben umgekehrt)

Delphi-Quellcode:

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    lv: TListView;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
    procedure lvSelectItem(Sender: TObject; Item: TListItem;
      Selected: Boolean);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
var
     Item : TListItem;
begin
     item := lv.Items.Add;
     Item.Data := Pointer(45);
     Item.Caption := 'Test';
end;

procedure TForm1.lvSelectItem(Sender: TObject; Item: TListItem;
  Selected: Boolean);
begin
     If Assigned(Item) then
          Caption := IntTostr(Integer(Item.Data));
end;

end.
