Listbox Scrollbar wegmachen?

[Stevie]

Durch nen kleinen Hack kannst du das Verhalten deiner TListBox noch verändern:

Delphi-Quellcode:

unit Unit1;

interface

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

type
  TListBox = class(StdCtrls.TListBox)
  protected
    procedure CreateParams(var Params: TCreateParams); override;
  end;

type
  TForm1 = class(TForm)
    ListBox1: TListBox;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
  ListBox1.Items.add('asfkljhasuilfhfuih fuihawiuh waeuifhw');
end;

{ TListBox }

procedure TListBox.CreateParams(var Params: TCreateParams);
begin
  inherited CreateParams(Params);
  if (Params.Style and WS_VSCROLL) <> 0 then
    Params.Style := Params.Style and not WS_VSCROLL;
end;

end.

Außerdem ist die Methode CreateParams besser als die oben vorgeschlagene.
