Correct way to replace CHeaderCtrl with custom version in a CListCtrl

Question

CListCtrl has a CHeaderCtrl 'built-in' and we want to override it with something customized, i.e a class which derives from CHeaderCtrl.

What's the best/correct way to do this, assuming we have a dialog CMyDlg which contains a CListCtrl m_List, and a custom header CCustomHeader.

Answer 1

Derive a class from CListCtrl and implement the handlers for the notification messages you need. The messages are named with LVN_ for messages about the list control and its items, and also HDN_ for things about the header control.

Answer 2

You should be able to call CWnd::SubclassWindow from your CCustomHeader member variable.

m_Header.SubclassWindow(m_List.GetHeaderCtrl()->GetSafeHwnd());
