Hallo,

Aus SwissDelphiCenter

...in einer Listbox einen horizontalen Scrollbalken anzeigen?
Autor: Thomas Stutz

Delphi-Quellcode:

procedure HorScrollBar(ListBox: TListBox; MaxWidth: Integer);
var
  i, w: Integer;
begin
  if MaxWidth = 0 then
    SendMessage(ListBox.Handle, LB_SETHORIZONTALEXTENT, MaxWidth, 0)
  else
  begin
    { get largest item }
    for i := 0 to ListBox.Items.Count - 1 do
      with ListBox do
      begin
        w := Canvas.TextWidth(Items[i]);
        if w > MaxWidth then
          MaxWidth := w;
      end;
    SendMessage(ListBox.Handle, LB_SETHORIZONTALEXTENT,
      MaxWidth + GetSystemMetrics(SM_CXFRAME), 0);
  end;
end;
