1. 新建一个SDI工程,去掉“Document/View architecture support”
2. 添加 CTreeView 类的派生类 CLeftView 作为分隔器的左侧视图,添加 CListView 的派生类 CRightView 作为右边视图。可能需要 #include <afxcview.h>
3. 在CLeftView类中添加成员变量 CTreeCtrl& m_tree; 在CRightView类中添加成员变量 CListCtrl& m_list; 并在构造函数中初始化
CLeftView::CLeftView() :m_tree(GetTreeCtrl())
{
}
CRightView::CRightView() :m_list(GetListCtrl())
{
}
4. 在主框架类 CMainFrame 类的头文件中,去掉 CChildView 类变量,添加 CSplitterWnd m_split;CLeftView* m_pLeftView;CRightView* m_pRightView;在CMainFrame的cpp文件中去掉CChildView的相关代码。
在CMainFrame类中添加虚函数OnCreateClient,该函数是在基类函数 CFrameWnd::OnCreate 执行的过程中回调OnCreateClient函数,主要用于创建视图类等客户区子窗口。
在CLeftView类中添加虚函数OnInitUpdate,该函数创建类之后第一个进入的函数,类似对话框的OnInitDialog函数。再添加TVN_SELCHANGEED消息映射函数,并修改代码调用CRightView的Refresh函数。
在CRightView类中添加虚函数OnInitUpdate,添加普通成员函数 Refresh。
代码如下:
