Cannot edit labels in a CListCtrl - c++

Question

I'm building a project with MFC Feature Pack. Is this project I have a window which includes a CView, which includes a CListCtrl-derived object. The object includes the LVS_EDITLABELS flag.
Somehow I cannot edit the CListCtrl icon labels by two-time clicking (not double-clicking) on the icon label. After I select the item with a single click, a second click just flashes the item (button down turns text background to white, button up turns it back to blue) and the edit control never appears.
I reduced this problem to the simplest form, and even with a plain CListCtrl object I cannot edit the labels.
I also found that:
This problem occurs in VS2008. It doesn't occur in a similar project built in VS2003.
I am able to edit the labels if I build a CListView instead of a CView+CListCtrl.
I am also able to edit the labels if I build a CFormView and put the CListCtrl inside the resource dialog.
Here's some code in the simplest form: the .h file:
// vwTerminaisTeste.h
//
#pragma once
// vwTerminaisTeste view
class vwTerminaisTeste : public CView
{
DECLARE_DYNCREATE(vwTerminaisTeste)
protected:
vwTerminaisTeste(); // protected constructor used by dynamic creation
virtual ~vwTerminaisTeste();
CListCtrl m_lstTerminais;
protected:
DECLARE_MESSAGE_MAP()
virtual void OnDraw(CDC* /*pDC*/);
public:
afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
afx_msg void OnSize(UINT nType, int cx, int cy);
};
and the .cpp file:
// vwTerminaisTeste.cpp : implementation file
//
#include "stdafx.h"
#include "vwTerminaisTeste.h"
// vwTerminaisTeste
IMPLEMENT_DYNCREATE(vwTerminaisTeste, CView)
vwTerminaisTeste::vwTerminaisTeste()
{
}
vwTerminaisTeste::~vwTerminaisTeste()
{
}
BEGIN_MESSAGE_MAP(vwTerminaisTeste, CView)
ON_WM_CREATE()
ON_WM_SIZE()
END_MESSAGE_MAP()
// vwTerminaisTeste message handlers
void vwTerminaisTeste::OnDraw(CDC* /*pDC*/)
{
CDocument* pDoc = GetDocument();
}
int vwTerminaisTeste::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CView::OnCreate(lpCreateStruct) == -1)
return -1;
m_lstTerminais.Create(WS_CHILD | WS_VISIBLE | LVS_EDITLABELS, CRect(0,0,1,1), this, 0);
m_lstTerminais.InsertItem(0, "Teste", 0);
return 0;
}
void vwTerminaisTeste::OnSize(UINT nType, int cx, int cy)
{
CView::OnSize(nType, cx, cy);
if (IsWindow(m_lstTerminais.GetSafeHwnd()))
m_lstTerminais.MoveWindow(0, 0, cx, cy);
}
This way I cannot edit labels.
To change it to a CListView I simply replaced CView by CListView and m_lstTerminais by GetListCtrl(), and removed the OnCreate and OnSize implementations. That way it worked.
Note: the vwTerminaisTeste is created from a CSplitterWndEx within a CMDIChildWndEx-derived class.

Answer 1

Well nobody solved this problem but I managed to go around it by changing the CView to a CFormView and building a resource dialog with a ListView control, attaching it to the CListCtrl-derived class.
If anyone still has any suggestions on how could I solve this problem entirely, I'd appreciate them.

This sounds like it may be a focus or command routing issue, although that doesn't explain why it works OK in VS2003. You might try routing the command and/or focus messages from the splitter ctrl to vwTerminaisTeste, and/or from the MDIChild to the splitter. If you haven't already, you may need to derive your own splitter window. The command/focus forwarding would be something like...
BEGIN_MESSAGE_MAP(MySplitter, CSplitterWnd)
ON_WM_SETFOCUS()
END_MESSAGE_MAP(...)
void MySplitter::OnSetFocus(CWnd* pOldWnd)
{
// forward focus to the view window
m_vwTerminaisTeste.SetFocus();
}
BOOL MySplitter::OnCmdMsg(UINT nID, int nCode, void* pExtra, AFX_CMDHANDLERINFO* pHandlerInfo)
{
// let the view have first crack at the command
if (m_vwTerminaisTeste.OnCmdMsg(nID, nCode, pExtra, pHandlerInfo))
return TRUE;
// otherwise, do default handling
return MySplitter::OnCmdMsg(nID, nCode, pExtra, pHandlerInfo);
}
