mfc对话框的二次切分

在这里插入代码片一：首先需要建两个类，目的是到时候定义划分的窗口种类
点击项目：项目图片再点击类向导
鼠标移动至添加类，点击添加mfc类， 类名命名为FrameList ，基类选 CListView， 类名命名为FrameEdit 基类选 CEditView。
随后点击类向导，添加消息函数WM_Create.再在消息函数中添加如下代码

CCreateContext ctxList, ctxEdit; ctxList.m_pNewViewClass = RUNTIME_CLASS(FrameEdit); ctxList.m_pCurrentDoc = NULL; ctxList.m_pNewDocTemplate = NULL; ctxList.m_pLastView = NULL; ctxList.m_pCurrentFrame = NULL;ctxEdit.m_pNewViewClass = RUNTIME_CLASS(FrameEdit); ctxEdit.m_pCurrentDoc = NULL; ctxEdit.m_pNewDocTemplate = NULL; ctxEdit.m_pLastView = NULL; ctxEdit.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_pFrameWnd = new CFrameWnd(); m_pFrameWnd->Create(strMyClass, _T(""), WS_CHILD, CRect(0, 0, 50, 50), this); m_pFrameWnd->ShowWindow(SW_SHOW); m_pFrameWnd->MoveWindow(0, 0, 500, 400);// and finally, create the splitter with the frame as // the parentm_wndSplitter.CreateStatic(m_pFrameWnd, 1, 2);//建立第一层构架 //m_wndSplitter.CreateStatic(this, 1, 2);//建立第一层构架 m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(FrameList), CSize(200,200), &ctxList); m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(FrameEdit), CSize(200, 200), &ctxEdit); m_wndSplitter2.CreateStatic(&m_wndSplitter, 3, 1, WS_CHILD | WS_VISIBLE | WS_BORDER,m_wndSplitter.IdFromRowCol(0,0));//建立第二层构架 m_wndSplitter.DeleteView(0,0);//动态拆分 m_wndSplitter2.CreateView(0, 0, RUNTIME_CLASS(FrameList), CSize(100, 100), &ctxList); m_wndSplitter2.CreateView(1, 0, RUNTIME_CLASS(FrameList), CSize(100,100), &ctxList); m_wndSplitter2.CreateView(2, 0, RUNTIME_CLASS(FrameList), CSize(100, 100), &ctxList); m_wndSplitter3.CreateStatic(&m_wndSplitter2, 1, 2, WS_CHILD | WS_VISIBLE | WS_BORDER,m_wndSplitter2.IdFromRowCol(0, 0)); m_wndSplitter3.CreateView(0, 0, RUNTIME_CLASS(FrameList), CSize(100, 100), &ctxList); return 0;

至此，主题部分写完。随后，我们需要在消息处理函数OnInitDialog中添加如下代码

// TODO: 在此添加额外的初始化代码 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(IDD_THREECUT_DIALOG)->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; // 除非将焦点设置到控件，否则返回 TRUE

写成这样还是会报错，因为很多变量没有定义，我们需要在 XXXDlg.h头文件中定义如下变量

public: afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct); CFrameWnd *m_pFrameWnd; CSplitterWnd m_wndSplitter; CSplitterWnd m_wndSplitter2;

到此，所有代码全部写完。运行时会有个中断，我也没有弄清原因，点忽略就会看到想要的结果。
