程序源代码
效果，如图：
1)创建一个MFC MDI应用程序，Wizard设置如图，
然后点Finish
2)CMyTreeView在CMyTreeView中新增三个函数，显示些示例数据virtual BOOL PreCreateWindow(CREATESTRUCT& cs);//本例没有使用该函数afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);virtual void OnInitialUpdate(); 源代码如下：int CMyTreeView::OnCreate(LPCREATESTRUCT lpCreateStruct){if (CTreeView::OnCreate(lpCreateStruct) == -1)return -1;
CTreeCtrl& m_treeCtrl = GetTreeCtrl();
HTREEITEM hItem; hItem = m_treeCtrl.InsertItem("node 1", TVI_ROOT);m_treeCtrl.Expand(hItem, TVE_EXPAND);
hItem = m_treeCtrl.InsertItem("node 2", TVI_ROOT);m_treeCtrl.Expand(hItem, TVE_EXPAND);
hItem = m_treeCtrl.InsertItem("node 3", hItem);m_treeCtrl.Expand(hItem, TVE_EXPAND);
return 0;}
void CMyTreeView::OnInitialUpdate(){CTreeView::OnInitialUpdate();CTreeCtrl& m_treeCtrl = GetTreeCtrl(); m_treeCtrl.ModifyStyle(0, WS_VISIBLE | WS_TABSTOP | TVS_HASBUTTONS | TVS_LINESATROOT | TVS_HASLINES | TVS_DISABLEDRAGDROP); }
CMyListView在CMyListView中新增三个函数，显示些示例数据virtual BOOL PreCreateWindow(CREATESTRUCT& cs);//本例没有使用该函数afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);virtual void OnInitialUpdate(); 源代码如下：
int CMyListView::OnCreate(LPCREATESTRUCT lpCreateStruct){if (CListView::OnCreate(lpCreateStruct) == -1)return -1;
// TODO: Add your specialized creation code hereCListCtrl& m_list = GetListCtrl();
CString sTmp = "asdf";//示例数据，代码中最好封装成函数int iPos = m_list.GetItemCount();m_list.InsertItem(iPos, sTmp);m_list.SetItemText(iPos, 1, sTmp+sTmp);
return 0;}
void CMyListView::OnInitialUpdate(){CListView::OnInitialUpdate();
CListCtrl& listCtrl = GetListCtrl();
LONG lStyle;lStyle = GetWindowLong(listCtrl.m_hWnd, GWL_STYLE); lStyle &= ~LVS_TYPEMASK; lStyle |= LVS_REPORT ;SetWindowLong(listCtrl.m_hWnd, GWL_STYLE, lStyle);
DWORD dwStyle = listCtrl.GetExtendedStyle();dwStyle |= LVS_EX_FULLROWSELECT | TVS_SHOWSELALWAYS | LVS_EX_FULLROWSELECT;listCtrl.SetExtendedStyle(dwStyle);
CRect rect;GetClientRect(&rect);
listCtrl.InsertColumn( 0, "信息", LVCFMT_CENTER, rect.Width()/2 );listCtrl.InsertColumn( 1, "信息2", LVCFMT_CENTER, rect.Width()/2 );}
CFrmChildTreeFrmChildTree.h
class CFrmChildTree : public CMDIChildWnd
#include "MyTreeView.h"声明一个CMyTreeView数据成员CMyTreeView m_FrmChildTree;
FrmChildTree.cppint CFrmChildTree::OnCreate(LPCREATESTRUCT lpCreateStruct){if (CMDIChildWnd::OnCreate(lpCreateStruct) == -1)return -1;
// TODO: Add your specialized creation code hereif (!m_FrmChildTree.Create(NULL, NULL, AFX_WS_DEFAULT_VIEW, CRect(0, 0, 0, 0), this, AFX_IDW_PANE_FIRST, NULL)) { TRACE0("Failed to create view window\n"); return -1; }
return 0;}
CFrmChildList
FrmChildList.h
class CFrmChildList : public CMDIChildWnd（with Splitter）
#include "MyListView.h"最好声明一个MyListView数据成员,用于记录Spliter创建的View，以便以后使用CMyListView* m_pMyListView;
FrmChildList.cppBOOL CFrmChildList::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext){ //return m_wndSplitter.Create(this, // 2, 2, // TODO: adjust the number of rows, columns // CSize(10, 10), // TODO: adjust the minimum pane size // pContext);// TODO: Add your specialized code here and/or call the base class CRect rect; GetClientRect(&rect); if (!m_wndSplitter.CreateStatic(this, 2, 1)) { return FALSE; } m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CMyListView),CSize(rect.Width(),rect.Height()/5 ),pContext);m_wndSplitter.CreateView(1, 0, RUNTIME_CLASS(CMyListView),CSize(rect.Width(),rect.Height()/5 ),pContext); m_pMyListView = (CMyListView*)m_wndSplitter.GetPane(0, 0); //... ...
return CMDIChildWnd::OnCreateClient(lpcs, pContext);}
3)修改menu：IDR_MFC_MDI_BUT_NO_TYPE增加：ID_FILE_TREE ID_FILE_LIST 两个菜单，分别为Tree 和 List在app中响应
app.h
#include "FrmChildList.h"#include "FrmChildTree.h"
CMDIChildWnd* m_pFrmChildList; //两个CMDIChildWnd对象 CMDIChildWnd* m_pFrmChildTree;
afx_msg void OnFileTree();afx_msg void OnFileList();
private: void ActiveChildWnd(CMDIChildWnd* m_pMDIChildWnd); app.cpp
BOOL CMFC_MDI_BUT_NO_DOCApp::InitInstance(){ ... ...if( NULL == m_pFrmChildList ) { m_pFrmChildList =pFrame->CreateNewChild( RUNTIME_CLASS(CFrmChildList), IDR_MFC_MDI_BUT_NO_TYPE, 0, 0); }... ...}
void CMFC_MDI_BUT_NO_DOCApp::OnFileNew() //屏蔽该代码，删除对应的New菜单{ //CMainFrame* pFrame = STATIC_DOWNCAST(CMainFrame, m_pMainWnd); create a new MDI child window //pFrame->CreateNewChild( //RUNTIME_CLASS(CChildFrame), IDR_MFC_MDI_BUT_NO_TYPE, m_hMDIMenu, m_hMDIAccel);}
void CMFC_MDI_BUT_NO_DOCApp::OnFileTree(){// TODO: Add your command handler code hereCMainFrame* pFrame = STATIC_DOWNCAST(CMainFrame, m_pMainWnd); if( NULL == m_pFrmChildTree ) { m_pFrmChildTree =pFrame->CreateNewChild( RUNTIME_CLASS(CFrmChildTree), IDR_MFC_MDI_BUT_NO_TYPE, 0, 0); } else { ActiveChildWnd( m_pFrmChildTree ); } m_pFrmChildTree->SetWindowTextA("Tree"); }
void CMFC_MDI_BUT_NO_DOCApp::OnFileList(){// TODO: Add your command handler code here]CMainFrame* pFrame = STATIC_DOWNCAST(CMainFrame, m_pMainWnd); if( NULL == m_pFrmChildList ) { m_pFrmChildList =pFrame->CreateNewChild( RUNTIME_CLASS(CFrmChildList), IDR_MFC_MDI_BUT_NO_TYPE, 0, 0); } else { ActiveChildWnd( m_pFrmChildList ); } m_pFrmChildList->SetWindowTextA("List");}
void CMFC_MDI_BUT_NO_DOCApp::ActiveChildWnd(CMDIChildWnd* m_pMDIChildWnd){ m_pMDIChildWnd->MDIActivate();}
