三個(gè)c++的MFC編程詳細(xì)步驟

1、2-7 編寫一個(gè)繪圖程序，程序運(yùn)行后，當(dāng)用戶在客戶區(qū)窗口按下鼠標(biāo)左鍵并移動(dòng)時(shí)，根據(jù)鼠標(biāo)移動(dòng)的軌跡繪制出指定的線段。第一步：在這添加（紅色加粗字體）class CMFC_52View : public CViewprotected: / create from serialization onlyCPoint m_ptOrigin;bool m_bDragging;HCURSOR m_hCross;第二步：在這添加（紅色加粗字體）CMFC_52View:CMFC_52View()m_bDragging=false;m_hCross=AfxGetApp()->LoadStandardCurs

2、or(IDC_CROSS);/ TODO: add construction code here第三步：擊鼠標(biāo)右鍵打開類向?qū)В砑覹M_LBUTTONDOMN;WM_MOUSEMOVE;WM_LBUTTONUP;如圖：然后在添加（紅色加粗字體）：void CMFC_52View:OnLButtonDown(UINT nFlags, CPoint point) SetCapture();:SetCursor(m_hCross);m_ptOrigin=point;m_bDragging=TRUE;/ TODO: Add your message handler code here and/or c

3、all defaultCView:OnLButtonDown(nFlags, point);void CMFC_52View:OnMouseMove(UINT nFlags, CPoint point) / TODO: Add your message handler code here and/or call defaultif(m_bDragging)CClientDC dc(this);dc.MoveTo(m_ptOrigin);dc.LineTo(point);m_ptOrigin=point;CView:OnMouseMove(nFlags, point);void CMFC_52V

4、iew:OnLButtonUp(UINT nFlags, CPoint point) / TODO: Add your message handler code here and/or call defaultif(m_bDragging)m_bDragging=false;ReleaseCapture();CView:OnLButtonUp(nFlags, point);第四步：在這添加（紅色加粗字體）：BOOL CMFC_52App:InitInstance()AfxEnableControlContainer();。/ The one and only window has been i

5、nitialized, so show and update it.m_pMainWnd->ShowWindow(SW_SHOW);m_pMainWnd->UpdateWindow();m_pMainWnd->SetWindowText("簡單的繪圖程序");return TRUE;效果圖：THE END2-8編寫一個(gè)多文檔程序，添加菜單項(xiàng)“繪圖”，并為之添加菜單命令“直線”“圓”“矩形”“多邊形”。當(dāng)選中某個(gè)菜單后，在其對(duì)于的菜單命令前劃一個(gè)勾，并把選擇的結(jié)構(gòu)顯示在視圖里。第一步：在這進(jìn)行菜單添加，如圖：（雙擊空白框即可進(jìn)行編輯）第二步：打開類向?qū)?，添?/p>

6、菜單命令處理函數(shù)，如圖：第三步：一一添加完八個(gè)函數(shù)確定后，點(diǎn)Edit Code,添加如下函數(shù)：（紅色加粗字體）void CMFC_53View:OnMfc53Line() CClientDC dc(this);dc.TextOut(100,100,"直線");/ TODO: Add your command handler code herem_mode=MODE_LINE;void CMFC_53View:OnMfc53Rectangle() CClientDC dc(this);dc.TextOut(200,200,"矩形");/ TODO: Add

7、 your command handler code herem_mode=MODE_RECTANGLE;void CMFC_53View:OnMfc53Polygon() CClientDC dc(this);dc.TextOut(150,150,"多邊形");/ TODO: Add your command handler code herem_mode=MODE_POLYGON;void CMFC_53View:OnMfc53Circle() CClientDC dc(this);dc.TextOut(180,180,"圓");/ TODO: Ad

8、d your command handler code herem_mode=MODE_CIRCLE;void CMFC_53View:OnUpdateMfc53Circle(CCmdUI* pCmdUI) pCmdUI->SetCheck(m_mode=MODE_CIRCLE);/ TODO: Add your command update UI handler code herevoid CMFC_53View:OnUpdateMfc53Line(CCmdUI* pCmdUI) pCmdUI->SetCheck(m_mode=MODE_LINE);/ TODO: Add you

9、r command update UI handler code herevoid CMFC_53View:OnUpdateMfc53Polygon(CCmdUI* pCmdUI) pCmdUI->SetCheck(m_mode=MODE_POLYGON);/ TODO: Add your command update UI handler code herevoid CMFC_53View:OnUpdateMfc53Rectangle(CCmdUI* pCmdUI) pCmdUI->SetCheck(m_mode=MODE_RECTANGLE);/ TODO: Add your

10、command update UI handler code here第四步：點(diǎn)擊這添加以下代碼（紅色加粗字體）：#if _MSC_VER > 1000#pragma once#endif / _MSC_VER > 1000typedef enum eProgModeMODE_LINE,MODE_RECTANGLE,MODE_CIRCLE,MODE_POLYGONPROGMODE;class CMFC_53View : public CView。/ Attributespublic:CMFC_53Doc* GetDocument();PROGMODE m_mode;CPoint m

11、_ptStart, m_ptOldEnd;BOOL m_bDragging;BOOL m_bFirst;HCURSOR m_hCross; / Operations第五步：點(diǎn)擊這添加以下代碼（紅色加粗字體）：CMFC_53View:CMFC_53View()m_mode = MODE_LINE;m_bDragging = FALSE;m_bFirst = FALSE;m_hCross=AfxGetApp()->LoadStandardCursor(IDC_CROSS);/ TODO: add construction code here效果圖：THE END2-9設(shè)計(jì)一個(gè)基于文檔視圖的應(yīng)

12、用程序要求如下： 1） 建立單文檔應(yīng)用程序，并添加菜單項(xiàng)“繪圖”，下面有菜單命令“直線”“矩形”“橢圓”。點(diǎn)擊菜單時(shí)，彈出消息框提醒“你點(diǎn)擊了XX菜單”。2） 工具條：給上述菜單添加相應(yīng)的工具條按鈕；3） 狀態(tài)欄：在狀態(tài)欄上添加一個(gè)面板，用于顯示當(dāng)前選擇的繪圖菜單操作；第一步：在這建立菜單資源，如圖：第二步：打開類向?qū)?，添加菜單命令處理函?shù)，如圖：第三步：添加完四個(gè)函數(shù)確定后，點(diǎn)Edit Code,添加如下函數(shù)：（紅色加粗字體）void CMFC_54View:OnMfc54Ellipse() MessageBox("你點(diǎn)擊了橢圓菜單");CStatusBar*pStatu

13、s=(CStatusBar*)AfxGetApp()->m_pMainWnd->GetDescendantWindow(ID_VIEW_STATUS_BAR);if(pStatus)pStatus->SetPaneText(1,"你點(diǎn)擊了橢圓菜單");/ TODO: Add your command handler code herevoid CMFC_54View:OnMfc54Line() MessageBox("你點(diǎn)擊了直線菜單");CStatusBar*pStatus=(CStatusBar*)AfxGetApp()->m

14、_pMainWnd->GetDescendantWindow(ID_VIEW_STATUS_BAR);if(pStatus)pStatus->SetPaneText(1,"你點(diǎn)擊了直線菜單");/ TODO: Add your command handler code herevoid CMFC_54View:OnMfc54Rectangle() MessageBox("你點(diǎn)擊了矩形菜單");CStatusBar*pStatus=(CStatusBar*)AfxGetApp()->m_pMainWnd->GetDescendantWindow(ID_VIEW_STATUS_BAR);if(pStatus)pStatus->SetPaneText(1,"你點(diǎn)擊了矩形菜單");/ TODO: Add your command handler code here第四步：在這添加工具欄按鈕，操作如圖：自己繪制相應(yīng)的圖形：雙擊新圖標(biāo)，設(shè)置工具欄屬性，ID要與菜單上相應(yīng)操作相同：一一完成“直線”，“矩形”，“橢圓”的設(shè)置。第
