创建

使用SDI模板创建，无需修改CView的基类。

单文档窗口分割

在父框架CMainFrame中添加 CSplitterWnd 成员变量。
重写父框架的 OnCreateClient 成员函数。
在 CFrameWnd::OnCreateClient 中调用 CreateStatic 成员函数，分割窗口为多行多列。
定义消息ID和消息处理函数，关联消息处理函数OnSelectViewChange

//MainFrm.h

#define NM_CAMERA (WM_USER+100) #define NM_ROBOTCONTROLLER (WM_USER+101) #define NM_OTHER (WM_USER+102)

protected: CSplitterWnd m_wndSplitter; afx_msg LRESULT OnSelectViewChange(WPARAM wParam, LPARAM lParam);

//MainFrm.cpp

#include “CSelectView.h” #include “CCameraView.h”

ON_MESSAGE(NM_CAMERA, OnSelectViewChange) ON_MESSAGE(NM_ROBOTCONTROLLER, OnSelectViewChange) ON_MESSAGE(NM_OTHER, OnSelectViewChange)

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext) { // TODO: Add your specialized code here and/or call the base class
```
 m_wndSplitter.CreateStatic(this, 1, 2);
 m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CMFCRoboticsView), CSize(190, 600), pContext);
 m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CMFCRoboticsView), CSize(520, 600), pContext);

 return TRUE;
 //return CFrameWnd::OnCreateClient(lpcs, pContext);  }
```
//手动创建一个新视图后，需要把该视图添加到文档类中 LRESULT CMainFrame::OnSelectViewChange(WPARAM wParam, LPARAM lParam) { CCreateContext context; CDocument* pDoc = this->GetActiveView()->GetDocument();
```
 if (wParam == NM_CAMERA) {
     context.m_pNewViewClass = RUNTIME_CLASS(CCameraView);
     context.m_pCurrentFrame = this;
     context.m_pCurrentDoc = pDoc;
     context.m_pLastView = (CFormView*)m_wndSplitter.GetPane(0, 1);
     m_wndSplitter.DeleteView(0, 1);
     m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CCameraView), CSize(520, 600), &context);
     CCameraView* pNewView = (CCameraView*)m_wndSplitter.GetPane(0, 1);
     m_wndSplitter.RecalcLayout();
     pNewView->OnInitialUpdate();
     m_wndSplitter.SetActivePane(0, 1);
 }

 return LRESULT();  }
```

CCreateContext

这是一个很重要的结构，在CMainFrame::OnCreateClient和CSplitterWnd::CreateView中需要设置正确的文档和视图类，特别是文档，这是把视图和文档关联的关键参数。

CSplitterWnd -> CWnd -> CCmdTarget -> CObject

CreateStatic

创建几行几列的静态拆分器窗口，

virtual BOOL CreateStatic(
    CWnd* pParentWnd, //父框架窗口
    int nRows, //行数
    int nCols, // 列数
    DWORD dwStyle = WS_CHILD | WS_VISIBLE, //窗口样式
    UINT nID = AFX_IDW_PANE_FIRST); //嵌入到另一个拆分器的窗口

CreateView

为静态拆分器窗口创建窗格

virtual BOOL CreateView(
    int row,
    int col,
    CRuntimeClass* pViewClass, //CView视图类
    SIZE sizeInit, //初始大小，如果初始大小小于剩余的空间，则使用剩余的空间，如果初始大小大于最大的窗口大小，则使用窗口大小
    CCreateContext* pContext);

IdFromRowCol

获取位于指定行和列的窗格的子窗口 ID。

int IdFromRowCol(
    int row,
    int col) const;

左侧菜单栏

基于CTreeView创建一个新类，该类需要引用头文件”afxcview.h”。

重写基类函数OnInitialUpdate，添加菜单项

重写菜单选择事件OnTvnSelchanged，向主框架窗口发送消息，消息参数包含需要切换的视图类型信息。

#include “afxcview.h”

private: CTreeCtrl* m_treeCtrl; CImageList m_imageList;

void CSelectView::OnInitialUpdate() { CTreeView::OnInitialUpdate();

 // TODO: Add your specialized code here and/or call the base class

 HICON icon = AfxGetApp()->LoadIconW(IDR_MAINFRAME);
 m_imageList.Create(30, 30, ILC_COLOR32, 1, 1);
 m_imageList.Add(icon);

 m_treeCtrl = &GetTreeCtrl();
 m_treeCtrl->SetImageList(&m_imageList, TVSIL_NORMAL);

 m_treeCtrl->InsertItem(_T("Robotics"), 0, 0, NULL);
 m_treeCtrl->InsertItem(_T("Other"), 0, 0, NULL);  }

void CSelectView::OnTvnSelchanged(NMHDR* pNMHDR, LRESULT* pResult) { LPNMTREEVIEW pNMTreeView = reinterpret_cast(pNMHDR); // TODO: Add your control notification handler code here *pResult = 0;

 HTREEITEM item = m_treeCtrl->GetSelectedItem();
 CString str = m_treeCtrl->GetItemText(item);

 if (str == _T("Cameras")) {
     ::PostMessage(AfxGetMainWnd()->GetSafeHwnd(), NM_CAMERA, (WPARAM)NM_CAMERA, (LPARAM)0);
 }
 if (str == _T("Robotics")) {
     ::PostMessage(AfxGetMainWnd()->GetSafeHwnd(), NM_ROBOTCONTROLLER, (WPARAM)NM_ROBOTCONTROLLER, (LPARAM)0);
 }
 else if (str == _T("Other")) {
     ::PostMessage(AfxGetMainWnd()->GetSafeHwnd(), NM_OTHER, (WPARAM)NM_OTHER, (LPARAM)0);
 }  }
