MFC CView into CDockablePane

Question

I need to place a CView derived class into a CDockablePane. Is there any code example somewhere, or can someone provide such code?

What I tried:

Apparently should be simple, online I found advice like "just create the view and set its parent to be the dialog or the dockable pane or what kind of window you want". But for some reason it doesn't work, maybe is because it needs a CFrameWnd, I don't know.

Anyway, I need to be able to do this without creating another document template class. Just to work with preexisting document and view classes.

Here's an example:

a class derived from CDockablePane:

//CRichEditPane .h

class CRichEditPane : public CDockablePane
{
    DECLARE_DYNAMIC(CRichEditPane)

public:
    CRichEditPane();
    virtual ~CRichEditPane();

protected:
    void AdjustLayout();
protected:
    DECLARE_MESSAGE_MAP()
public:
    afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
    afx_msg void OnSize(UINT nType, int cx, int cy);
};

//CRichEditPane .cpp

IMPLEMENT_DYNAMIC(CRichEditPane, CDockablePane)

CRichEditPane::CRichEditPane()
{

}

CRichEditPane::~CRichEditPane()
{
}


BEGIN_MESSAGE_MAP(CRichEditPane, CDockablePane)
    ON_WM_CREATE()
    ON_WM_SIZE()
END_MESSAGE_MAP()


// CRichEditPane message handlers


int CRichEditPane::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (CDockablePane::OnCreate(lpCreateStruct) == -1)
        return -1;

    CRuntimeClass *pClass = RUNTIME_CLASS(CRichEditViewInPane);

    // calling constructor using IMPLEMENT_DYNCREATE macro
    CRichEditViewInPane *pView = (CRichEditViewInPane*)pClass->CreateObject();


    if (!pView->Create(NULL, NULL, AFX_WS_DEFAULT_VIEW, CRect(0,0,0,0), this, AFX_IDW_PANE_FIRST, NULL))
    {
        return -1;
    }

    CRichEditCtrl ctrl;
    ctrl.Create(WS_CHILD, CRect(0, 0, 0, 0), this, 10991);

    return 0;
}


void CRichEditPane::OnSize(UINT nType, int cx, int cy)
{
    CDockablePane::OnSize(nType, cx, cy);

    AdjustLayout();
}

a view class derived from CView:

//CRichEditViewInPane .h

class CRichEditViewInPane : public CRichEditView
{
    DECLARE_DYNCREATE(CRichEditViewInPane)

protected:
    CRichEditViewInPane();           // protected constructor used by dynamic creation
    virtual ~CRichEditViewInPane();

public:
#ifdef _DEBUG
    virtual void AssertValid() const;
#ifndef _WIN32_WCE
    virtual void Dump(CDumpContext& dc) const;
#endif
#endif

protected:
    DECLARE_MESSAGE_MAP()
};

//CRichEditViewInPane. cpp

IMPLEMENT_DYNCREATE(CRichEditViewInPane, CRichEditView)

CRichEditViewInPane::CRichEditViewInPane()
{

}

CRichEditViewInPane::~CRichEditViewInPane()
{
}

BEGIN_MESSAGE_MAP(CRichEditViewInPane, CRichEditView)
END_MESSAGE_MAP()
