基于对话框的MFC项目实现窗口分割

1. 新建一个MFC对话框程序MySplitter。 再插入两个Dialog资源 ，这里一定要选择IDD_FORMVIEW类别的对话框，对这两个对话框分别新建类CMyFormView0
和CMyFormView1，基类别选CDialog，一定要选择CFormView。

2.主对话框类MySplitterDlg.h中新增两个成员变量

CFrameWnd*      m_pMyFrame;    // 分隔窗口
CSplitterWnd    m_cSplitter;     // 左右分隔

3. CMySplitterDlg中增加WM_CREATE的消息响应，编辑OnCreate()

int CMySplitterDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CDialog::OnCreate(lpCreateStruct) == -1)
return -1;
// 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.
//需要注册窗口类
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,_T(""), WS_CHILD,   CRect(0,0,300,300), this);
m_pMyFrame->ShowWindow(SW_SHOW);

// and finally, create the splitter with the frame as the parent
m_cSplitter.CreateStatic(m_pMyFrame,1, 2); //在Frame里切分视图窗口为1×2，就是一行两列
m_cSplitter.CreateView(0,0, RUNTIME_CLASS(CMyFormView0),   CSize(100,100), NULL);//第一行一列
m_cSplitter.CreateView(0,1, RUNTIME_CLASS(CMyFormView1), CSize(100,100), NULL);//第一行二列

return 0;
}

4.在CMySplitterDlg::OnInitDialog()中显示Frame

int CMySplitterDlg::OnInitDialog()
{
CDialog::OnInitDialog();

CRect cRect;
GetWindowRect(&cRect);
ScreenToClient(&cRect);
m_pMyFrame->MoveWindow(&cRect);
m_pMyFrame->ShowWindow(SW_SHOW);

return TRUE;
}
