Question

我需要将CView派生类放入CDockablePane。在某处有代码示例，或者某人可以提供这样的代码吗？

我尝试了什么：

显然应该很简单，在网上我找到了一些建议，比如“只需创建视图并将其父级设置为对话框或可停靠窗格或您想要的窗口类型”。但由于某些原因它不起作用，也许是因为它需要一个CFrameWnd，我不知道。

无论如何，我需要能够在不创建其他文档模板类的情况下执行此操作。只是为了使用预先存在的文档和视图类。

以下是一个例子：

派生自CDockablePane的类：

// 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();
}

从CView派生的视图类：

// 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()

MFC CView进入CDockablePane
