小弟我已实现静态嵌套分割窗口，求动态切换分割方式的方法

我已实现静态嵌套分割窗口，求动态切换分割方式的方法。
我已实现静态嵌套分割窗口，求动态切换分割方式的方法。

我的例程是基于SDI的MFC程序，视图类基于CScrollView，共有4个视图类。

在MainFrm类中定义了2个分割窗口，用于进行嵌套分割。

CSplitterWnd m_wndSplitter;
// 新增加一个嵌套分割
CSplitterWnd m_wndSplitterSub;

在MainFrm类OnCreateClient中实现了静态嵌套分割。可以实现具有4个视图窗口的5中分割模式如下：
1 | 2
--|--
3 | 4

1 |
__|
2 | 4
--|
3 |

| 1
|__
4 | 2
|--
| 3

1 | 2 | 3
------------
4

4
------------
1 | 2 | 3

我目前只能是在更改分割方式后，存储分割方式，然后重新启动程序，
在MainFrm类OnCreateClient中根据存储的分割模式来实现了静态嵌套分割。
但是不知道如何实现动态切换分割方式，请高人指点。

分不够我可以增加。
期待高人指点，困扰了我很久。

网上有动态分割窗口的类，百度一下。

是动态切换view吗？
