在CView而不是CMainFrame中创建停靠窗格

CMainFrame CreateDockingWindows() .

OnInitialUpdate() 框架类 包括将主框架设置为父窗口。

对接窗口的位置会自动保存到注册表中,但不会恢复,因为框架初始化时对接窗口还不存在。

用视图创建停靠窗口是一个好主意还是我应该期待更多的问题?有没有更好的方法来实现我的目标?

提前谢谢!

我从一个类派生窗格,该类实现了我需要的“类CView”行为:

/**
 * \brief Mimics some of the behavior of a CView
 *
 * CDockablePane derived class which stores a pointer to the document and offers
 * a behavior similar to CView classes.
 *
 * Since the docking panes are child windows of the main frame,
 * they have a longer live time than a view. Thus the (de-)initialization code
 * cannot reside in the CTor/DTor.
 */
class CPseudoViewPane :
    public CDockablePane,
{
    DECLARE_DYNAMIC(CPseudoViewPane)

public:
    /// Initializes the pane with the specified document
    void Initialize(CMyDoc* pDoc);

    void DeInitialize();

    /// Checks if window is valid and then forwards call to pure virtual OnUpdate() method.
    void Update(const LPARAM lHint);

protected:
    CPseudoViewPane();
    virtual ~CPseudoViewPane();


    CMyDoc* GetDocument() const { ASSERT(NULL != m_pDocument); return m_pDocument; }

    CMainFrame* GetMainFrame() const;

    /**
     * This method is called after a document pointer has been set with #Initialize().
     * Override this in derived classes to mimic a view's "OnInitialUpdate()-behavior".
     */
    virtual void OnInitialUpdate() = 0;

    /**
     * Called by #Update(). Overrider to mimic a view's "OnUpdate()-behavior".
     * This method has a simplified parameter list. Enhance this if necessary.
     */
    virtual void OnUpdate(const LPARAM lHint) = 0;

    DECLARE_MESSAGE_MAP()

private:
    CMyDoc* m_pDocument;
};
