GeneralCListCtrl question (custom) Pin

Hi all,

Like everyone who has done any CListCtrl work, I want to make some changes (sub-item editing and the like). Easy enough to do, done it already with a CListView. To save myself from having to make the same change over and over I thought it would be nice to make a proper CListViewEx style class derived from CCtrlView. I'm sure everyone who's tried this knows the problem, silly GetListCtrl() casts a pointer to itself Frown | :-( Anyway, I reckon I have a cunning solution (someone please stop me if this won't work!) I'm going to derive a new CListCtrl (called CListCtrlEx) add the changes to it (I've actually already done this) and it works via subclassing (i.e. create a ListCtrl with the dialog editor and select the subclass to be ListCtrlEx).
Now in order to do the cunning bit with the CCtrlView I need to register this new class with Windows, no problem, stole some code from a tutorial on this site and all works well, the class registers. However, and here's the problem (at last), if I create a custom control with the dialog editor, set the class accordingly and do all the necessary member modifications (i.e. add DDX stuff), the app. compiles fine, but nothing appears on my little test dialog, anyone know why? I've included the code below, it's so simple and I can't see why the ListCtrl won't paint, unless I can get the registered control to draw itself my cunning plan is going to fail Frown | :-(

Here's the whole thing (bar the dialog bits):
CListCtrlEx::CListCtrlEx()
{
TRACE("CListCtrlEx() is constructing....\n");
if(RegisterWindowClass()) TRACE("CListCtrlEx() - Class registered.\n");
}

CListCtrlEx::~CListCtrlEx()
{
TRACE("CListCtrlEx() is destructing....\n");
}

bool CListCtrlEx::RegisterWindowClass()
{
WNDCLASS wndcls;
HINSTANCE hInst = AfxGetInstanceHandle();
bool status = false;

if(!(::GetClassInfo(hInst, _T("CListCtrlEx"), &wndcls)))
{
// otherwise we need to register a new class
wndcls.style = CS_DBLCLKS | CS_HREDRAW | CS_VREDRAW;
wndcls.lpfnWndProc = ::DefWindowProc;
wndcls.cbClsExtra = wndcls.cbWndExtra = 0;
wndcls.hInstance = hInst;
wndcls.hIcon = NULL;
wndcls.hCursor = AfxGetApp()->LoadStandardCursor(IDC_ARROW);
wndcls.hbrBackground = (HBRUSH) COLOR_BTNSHADOW;
wndcls.lpszMenuName = NULL;
wndcls.lpszClassName = _T("CListCtrlEx");

if(!AfxRegisterClass(&wndcls))
{
AfxThrowResourceException();
status = false;
}
else status = true;
}
else TRACE("CListCtrlEx()::RegisterWindowClass() - Class already registered.\n");

return(status);
}

BEGIN_MESSAGE_MAP(CListCtrlEx, CListCtrl)
//{{AFX_MSG_MAP(CListCtrlEx)
ON_NOTIFY_REFLECT(NM_CLICK, OnClick)
//}}AFX_MSG_MAP
END_MESSAGE_MAP()

/////////////////////////////////////////////////////////////////////////////
// CListCtrlEx message handlers

void CListCtrlEx::OnClick(NMHDR* pNMHDR, LRESULT* pResult)
{
NMLISTVIEW *lv = (NMLISTVIEW *)pNMHDR;

TRACE("CListCtrlEx::OnClick() - Got a click (at %02d,%02d)\n",lv->ptAction.x,lv->ptAction.y);
*pResult = 0;
}

void CListCtrlEx::PreSubclassWindow()
{
TRACE("CListCtrlEx::PreSubclassWindow() - Running....\n");
CListCtrl::PreSubclassWindow();
}
