Change LVS_ALIGNLEFT by LVS_ALIGNTOP

[_Flaviu]

How can I change LVS_ALIGNLEFT by LVS_ALIGNTOP (of an CListCtrl) at runtime ? The list has LVS_ICON style already ... Thank you.

What you are looking for is the funtion CWnd::ModifyStyle.

The good thing about pessimism is, that you are always either right or pleasently surprised.

I tried both solutions:

ListView_SetExtendedListViewStyleEx(m_List.GetSafeHwnd(), LVS_ALIGNMASK, LVS_ALIGNLEFT);

and

m_List.ModifyStyle(LVS_ALIGNTOP, LVS_ALIGNLEFT);

none of them are working ... I am not figure out why ...

You need to use

DWORD dwStyle = GetWindowLong(m_hWnd, GWL_STYLE);
// modify the style mask as required
SetWindowLong(m_hWnd, GWL_STYLE, dwStyle);

There are probably some MFC shortcuts to this.

"There are probably some MFC shortcuts to this" Yes, there is ModifyStyle (ModifyStyleEx), but seems not working either ...

Maybe you are not doing it correctly.

Is working by

ModifyStyle(LVS_ALIGNMASK, LVS_ALIGNTOP);

I noticed something: in order to work correctly, before I change the aligment style, I have to setup scrollbars of list control to top/bottom ... orelse, the list looks uggly (all items are bad drawned) ... it is logical to happend that ? I am thinking that if I setup vertical scrollbar on some position, if I change the aligment style to horizontal, it doesn't fit at he same horizontal position ...
