Controlling width/layout in CListCtrl (Icon view)

Question

Apart from the fact I still can't see why this class fills columns and scrolls horizontally, rather than filling rows and scrolling vertically, I'm confused how the width of items is controlled. I'm seeing quite a lot of padding (50-80 pixels) between the longest item in a column and the next column which means wasted space.

Is it controllable?

Somebody else asked about scrolling, here is the answer.

If you are referring to column width then you can change it using:

CListCtrl list;
list.InsertColumn(0, _T("Column1"));
list.InsertItem(0, _T("Item with a long name"));
list.SetColumnWidth(0, LVSCW_AUTOSIZE_USEHEADER);
