對(duì)話框程序調(diào)用Frame框架實(shí)現(xiàn)打印的具體細(xì)節(jié)

1、對(duì)話框程序調(diào)用Frame框架實(shí)現(xiàn)打印的具體細(xì)節(jié)網(wǎng)上搜索了幾天關(guān)于對(duì)話框的打印問題大部分都抄來抄去的實(shí)現(xiàn)對(duì)話框所見即所得模式，其實(shí)就是在對(duì)話框上繪制一般還是使用打印預(yù)覽然后打印的功能吧.咱們就一步一步的來實(shí)現(xiàn)吧.最后本文給出一個(gè)可行的方案，也是網(wǎng)上收集的例子.PS:由于個(gè)人修改的所以改掉了類名也算一遍梳理吧.再PS:程序編譯可能還會(huì)有一些小錯(cuò)誤，一般是符號(hào)不同造成的了例如雙引號(hào)，括號(hào)的全半角差異-II下面進(jìn)入正題：1用MFC應(yīng)用向?qū)?chuàng)建對(duì)話框應(yīng)用程序，設(shè)主對(duì)話框類為MyPrintPreviewDIg程序名稱為MyPrintPreview）,在主對(duì)話框上放一按鈕，（標(biāo)題：打印預(yù)覽，ID：IDC_B

3、reviewView（我就沒找到這個(gè)類），注意在頭其定義頭文件中加入包含afxpriv.h）,用于打印預(yù)覽界面的視圖類。3、對(duì)新生成的各類修改如下：CSevFrame類：增加公有數(shù)據(jù)成員CMyPrintPreviewDlg*m_pOIdWnd用于保存主對(duì)話框?qū)ο螅籆SevView*mpView;/用于保存視圖類對(duì)象；由于存在CMyPrintPreviewDlg類HCSevView類,所以要包含兩個(gè)頭文件includeCMyPrintPreviewDlg.hincludeCSevView.h重載構(gòu)造函數(shù)，保存對(duì)主對(duì)話框?qū)ο笾羔槪瑒?chuàng)建窗口/頭文件聲明CSevFrame(CMyPrintPrevie

4、wDlg*pOld);cpp文件定義CSevFrame:CSevFrame(CMyPrintPreviewDlg*pOld)m_pOldWnd=pOld;if(!Create(NULL,打印預(yù)覽,WS_OVERLAPPEDWINDOW|FWS_ADDTOTITLE,CRect(200,200,500,500)TRACE0(Failedtocreateviewwindown);修改析構(gòu)函數(shù)，讓主對(duì)話框顯示CSevFrame:CSevFrame()m_pOldWnd-ShowWindow(SW_SHOW);用ClassWizard增加WM_CREATE消息處理函數(shù)，關(guān)聯(lián)CSevView視圖對(duì)象；調(diào)

5、用其OnFilePrintPreview函數(shù)進(jìn)行打印預(yù)覽若要直接打印，可直接向其發(fā)送消息；隱藏主對(duì)話框。此項(xiàng)照著copy就好了嘿嘿intCSevFrame:OnCreate（LPCREATESTRUCTlpCreateStruct）if（CFrameWnd:OnCreate（lpCreateStruct）=-1）return-1;CCreateContextcontext;context.m_pNewViewClass=RUNTIME_CLASS(CSevView);context.m_pCurrentFrame=this;context.m_pCurrentDoc=NULL;context.

6、m_pLastView=NULL;m_pView=STATIC_DOWNCAST(CSevView,CreateView(&context);if(m_pView!=NULL)mView-ShowWindow(SW_SHOW);SetActiveView(m_pView);Setlcon(m_pOldWnd-GetIcon(FALSE),FALSE);Setlcon(m_pOldWnd-GetIcon(TRUE),TRUE);ShowWindow(SW_MAXIMIZE);CWinApp*pApp=AfxGetApp();pApp-m_pMainWnd=this;m_pView-OnFileP

7、rintPreview();mView-SendMessage(WM_COMMAND,ID_FILE_PRINT);直接打印m_pOldWnd-ShowWindow(SW_HIDE);return0;修改CSevView類修改構(gòu)造函數(shù)：將坐標(biāo)射模式置為缺省模式。CSevView:CSevView()m_nMapMode=MM_TEXT;增加消息映射實(shí)現(xiàn)打印。ONCOMMAND(IDFILEPRINT,CViewQnFilePrint)重載虛函數(shù)OnPreparePrinting,調(diào)申DoPreparePrinting牛成申干打印或打印預(yù)覽的設(shè)備描述表。BOOLCSevView:OnPrepar

8、ePrinting(CPrintInfo*pInfo)returnDoPreparePrinting(pInfo);增加公有函數(shù)OnFilePrintPreview,調(diào)用DoPrintPreview實(shí)現(xiàn)打印預(yù)覽，該函數(shù)需要傳入四個(gè)參數(shù)：1打印預(yù)覽工具條資源ID,2執(zhí)行打印及打印預(yù)覽的視圖對(duì)象指針，3打印預(yù)覽界面視圖類的CRuntimeClass指針，I4打印預(yù)覽狀態(tài)類CPrintPreviewState對(duì)象扌指針。voidCSevView:OnFilePrintPreview()CPrintPreviewState*pState=newCPrintPreviewState;pState-lpf

9、nCloseProc=_AfxMyPreviewCloseProc/設(shè)置打印預(yù)覽窗口關(guān)閉時(shí)的調(diào)用函數(shù)；if(!DoPrintPreview(AFX_IDD_PREVIEW_TOOLBAR,this,RUNTIME_CLASS(CSevPreviewView),pState)TRACE0(Error:DoPrintPreviewfailed.n);AfxMessageBox(AFX_IDP_COMMAND_FAILURE);deletepState;在Myviewcpp文件中增加全局函數(shù)，AfxMyPreviewCloseProc,當(dāng)單擊打印預(yù)覽窗口關(guān)閉按鈕時(shí)被調(diào)用。/頭文件聲明BOOLCALL

10、BACK_AfxMyPreviewCloseProc(CFrameWnd*pFrameWnd);/cpp文件定義BOOLCALLBACK_AfxMyPreviewCloseProc(CFrameWnd*pFrameWnd)ASSERT_VALID(pFrameWnd);CSevPreviewView*pView=(CSevPreviewView*)pFrameWnd-GetDlgItem(AFX_IDW_PANE_FIRST);ASSERT_KINDOF(CPreviewView,pView);pView-OnPreviewClose();returnFALSE;4、修改CSevPreview

11、View類，增加工具欄按鈕的消息響應(yīng)函數(shù)OnPreviewClose(),OnPreviewPrint(),由干此類較簡單，列出該類代碼如下(注意粗體部分)：SevPreviewViewh/SevPreviewView.h:interfacefortheCSevPreviewViewclass./if!defined(AFX_MYPREVIEWVIEW_H_0AE8B670_B1AE_11DA_812E_00E04C39032F_INCLUDEDdefineAFX_MYPREVIEWVIEW_H_0AE8B670_B1AE_11DA_812E_00E04C39032F_INCLUDED_if_
