在对话框（CDialog）中使用分割窗(CSplitterWnd)

可以使用以下三个步骤在对话框中创建分割窗：  
  
1. In the OnCreate function or your CDialog, register a new WindowClass by calling "AfxRegisterWndClass".  
  
在你的CDialog类的OnCreate函数中使用AfxRegisterWndClass注册一个新的窗口类。  
  
2. Create a new CFrameWnd by using the "new" operator and initialize it.  
  
使用new操作符创建一个CFrameWnd，并对其进行初始化。  
  
3. Create your splitter by using the new CFrameWnd you just created as the parent.  
  
在步骤2中创建的CFrameWnd上创建分割窗。

int CMyDialog::OnCreate(LPCREATESTRUCT lpCreateStruct) 
    { 
        if (CDialog::OnCreate(lpCreateStruct) == -1) 
          return -1; 
    
        // Initialize a context for the view. CMyTreeView is my view and 
        // is defined as :  class CMyTreeView : public CTreeView. 
        CCreateContext ccc; 
        ccc.m_pNewViewClass      = RUNTIME_CLASS(CMyTreeView); 
        ccc.m_pCurrentDoc           = NULL; 
        ccc.m_pNewDocTemplate = NULL; 
        ccc.m_pLastView              = NULL; 
        ccc.m_pCurrentFrame       = NULL; 
    
        // Because the CFrameWnd needs a window class, we will create 
        // a new one. I just copied the sample from MSDN Help. 
        // When using it in your project, you may keep CS_VREDRAW and 
        // CS_HREDRAW and then throw the other three parameters. 
        CString strMyClass = AfxRegisterWndClass(CS_VREDRAW | 
                             CS_HREDRAW, 
                             ::LoadCursor(NULL, IDC_ARROW), 
                             (HBRUSH) ::GetStockObject(WHITE_BRUSH), 
                             ::LoadIcon(NULL, IDI_APPLICATION)); 
    
        // Create the frame window with "this" as the parent 
        m_pMyFrame = new CFrameWnd; 
        m_pMyFrame->Create(strMyClass,"", WS_CHILD, 
                                             CRect(0,0,1,1), this); 
        m_pMyFrame->ShowWindow(SW_SHOW); 
        m_pMyFrame->MoveWindow(0,0,300,300); 
    
        // and finally, create the splitter with the frame as 
        // the parent 
        m_wndSplitter.CreateStatic(pMyFrame,1, 2); 
        m_wndSplitter.CreateView(0,0, RUNTIME_CLASS(CMyTreeView), 
                                                   CSize(100,100), &ccc); 
        m_wndSplitter.CreateView(0,1, RUNTIME_CLASS(CMyTreeView), 
                                                   CSize(100,100), &ccc); 
    } 
    
    BOOL CMyDialog::OnInitDialog() 
    { 
      CDialog::OnInitDialog(); 
      CRect rect; 
    
      // Get the rectangle of the custom window. The custom window 
      // is just a a big button that is not visible and is disabled. 
      // It's a trick to not use coordinates directly. 
      GetDlgItem(IDC_CUTSOM_WINDOW)->GetWindowRect(&rect); 
    
      // Move the splitter 
      ScreenToClient(&rect); 
      m_pFrameWnd->MoveWindow(&rect); 
      m_pFrameWnd->ShowWindow(SW_SHOW); 
      m_wndSplitter.MoveWindow(0,0, rect.Width(), rect.Height()); 
      m_wndSplitter.ShowWindow(SW_SHOW); 
    
      return TRUE;  // return TRUE unless you set the focus to a 
                    // control 
                    // EXCEPTION: OCX Property Pages should return 
                    // FALSE 
    }
