如何将 CFormView 派生类附加到 CMFCTabCrtl？

我创建了带有基类 CFormView、功能区、标题栏等的 MFC MDI 项目。在CMainFrame中，OnCreate()调用EnableMDITabbedGroups()，它会自动添加一个选项卡并附加 CMyProjectView 视图。现在我想添加第二个选项卡并将第二个视图附加到该选项卡。我创建了新对话框并向其中添加了 CFormView 派生类。

这是代码：

void CMainFrame::CreateViews()
{
const CObList &tabGroups = GetMDITabGroups();
CMFCTabCtrl *wndTab = (CMFCTabCtrl*)tabGroups.GetHead();
wndTab->m_bEnableWrapping = TRUE;

CRect dummyRect;
CNewFormView *pNewView = (CNewFormView*)RUNTIME_CLASS(CNewFormView)->CreateObject();
((CWnd*)pNewView)->Create(NULL, NULL, WS_CHILD, dummyRect, wndTab, IDD_NEWFORMVIEW); 

wndTab->AddTab(pNewView, _T("NewTab"), -1, TRUE);

}

现在，我很确定我错过了一些微不足道的事情或者一起走错了方向，但我无法显示新视图。另外，我无法在 CMainFrame 中捕获 AFX_WM_CHANGE_ACTIVE_TAB 或 AFX_WM_CHANGING_ACTIVE_TAB 。消息从 CMFCBaseTabCtrl::FireChangingActiveTab 发送，但没有任何反应。

I have created MFC MDI project with base class CFormView, ribbon, caption bar etc.
In CMainFrame, OnCreate() calls EnableMDITabbedGroups() which automatically adds one tab
and attaches CMyProjectView view. Now I want to add second tab and attach second view to that tab. I created new dialog and added CFormView derived class to it.

Here is the code:

void CMainFrame::CreateViews()
{
const CObList &tabGroups = GetMDITabGroups();
CMFCTabCtrl *wndTab = (CMFCTabCtrl*)tabGroups.GetHead();
wndTab->m_bEnableWrapping = TRUE;

CRect dummyRect;
CNewFormView *pNewView = (CNewFormView*)RUNTIME_CLASS(CNewFormView)->CreateObject();
((CWnd*)pNewView)->Create(NULL, NULL, WS_CHILD, dummyRect, wndTab, IDD_NEWFORMVIEW); 

wndTab->AddTab(pNewView, _T("NewTab"), -1, TRUE);

}

Now, I'm pretty sure I missed something trivial or went in wrong direction all together,
but I can't get new view to show up. Also, I can't catch AFX_WM_CHANGE_ACTIVE_TAB or AFX_WM_CHANGING_ACTIVE_TAB in CMainFrame. Message gets send from CMFCBaseTabCtrl::FireChangingActiveTab but nothing happens.
