Question

I have a TListView that displays small thumbnails (ViewStyle:=vsIcon).
At run time I assign images to to items:

  for i := 0 to Total - 1 DO
   with ListView.Items.Add DO
     begin
      Caption := 'Item ' + IntToStr(i);
      ImageIndex := i;
     end;

At start up the form is not very wide and the thumbnails are shown on only 3 columns. Unfortunately, If I resize the form (and the ListView) the column count will remain 3 and in the right side I will have a lot of white space.

This won’t work also:

procedure TForm1.FormCreate(Sender: TObject);
begin
 ListView.IconOptions.AutoArrange := TRUE;
end;

How do I rearrange the items to fill the empty space?
There is any property like AutoArrange?

---

Update:
I deleted the old control and I put a new one on the form.
Now ListView.IconOptions.AutoArrange works. There was something (some settings I made) in the previous control that prevented AutoArrange from working.

There is a property like AutoArrange. It belongs to the IconOptions property instead of directly to the list view.

ListView1.IconOptions.AutoArrange := True;

To make a one-time arrangement of the icons, you can call ListView_Arrange instead.
