VC程序設(shè)計大作業(yè)之繪制矩形

/武漢輕工大學VC++程序設(shè)計大作業(yè)鼠標點擊繪制矩形 院系電氣和電子工程學院班級學號1204姓名日期2013.11.221題目編寫MFC下的單文檔程序，通過鼠標點擊選擇兩個點，作為矩形左上角、右下角，然后繪制矩形。（對應(yīng)12題）2思路首先點擊鼠標，選中左上角，然后拖動鼠標，在右下角拿起，這樣矩形就就可以實現(xiàn)了。3程序?qū)崿F(xiàn)過程首先建立MFC單文檔程序然后建立類向?qū)砑邮髽耸聞?wù)添加CPoint成員變量m_OrigPoint4關(guān)鍵代碼//RectangleView.cpp:implementationoftheCRectangleViewclass//#include"stdafx.h"#include"Rectangle.h"#include"RectangleDoc.h"#include"RectangleView.h"#ifdef_DEBUG#definenewDEBUG_NEW#undefTHIS_FILEstaticcharTHIS_FILE[]=__FILE__;#endif///////////////////////////////////////////////////////////////////////////////CRectangleViewIMPLEMENT_DYNCREATE(CRectangleView,CView)BEGIN_MESSAGE_MAP(CRectangleView,CView) //{{AFX_MSG_MAP(CRectangleView) ON_WM_LBUTTONDOWN() ON_WM_LBUTTONUP() //}}AFX_MSG_MAP //Standardprintingcommands ON_COMMAND(ID_FILE_PRINT,CView::OnFilePrint) ON_COMMAND(ID_FILE_PRINT_DIRECT,CView::OnFilePrint) ON_COMMAND(ID_FILE_PRINT_PREVIEW,CView::OnFilePrintPreview)END_MESSAGE_MAP()///////////////////////////////////////////////////////////////////////////////CRectangleViewconstruction/destructionCRectangleView::CRectangleView(){ //TODO:addconstructioncodehere}CRectangleView::~CRectangleView(){}BOOLCRectangleView::PreCreateWindow(CREATESTRUCT&cs){ //TODO:ModifytheWindowclassorstylesherebymodifying //theCREATESTRUCTcs returnCView::PreCreateWindow(cs);}///////////////////////////////////////////////////////////////////////////////CRectangleViewdrawingvoidCRectangleView::OnDraw(CDC*pDC){ CRectangleDoc*pDoc=GetDocument(); ASSERT_VALID(pDoc); //TODO:adddrawcodefornativedatahere}///////////////////////////////////////////////////////////////////////////////CRectangleViewprintingBOOLCRectangleView::OnPreparePrinting(CPrintInfo*pInfo){ //defaultpreparation returnDoPreparePrinting(pInfo);}voidCRectangleView::OnBeginPrinting(CDC*/*pDC*/,CPrintInfo*/*pInfo*/){ //TODO:addextrainitializationbeforeprinting}voidCRectangleView::OnEndPrinting(CDC*/*pDC*/,CPrintInfo*/*pInfo*/){ //TODO:addcleanupafterprinting}///////////////////////////////////////////////////////////////////////////////CRectangleViewdiagnostics#ifdef_DEBUGvoidCRectangleView::AssertValid()const{ CView::AssertValid();}voidCRectangleView::Dump(CDumpContext&dc)const{ CView::Dump(dc);}CRectangleDoc*CRectangleView::GetDocument()//non-debugversionisinline{ ASSERT(m_pDocument->IsKindOf(RUNTIME_CLASS(CRectangleDoc))); return(CRectangleDoc*)m_pDocument;}#endif//_DEBUG///////////////////////////////////////////////////////////////////////////////CRectangleViewmessagehandlersvoidCRectangleView::OnLButtonDown(UINTnFlags,CPointpoint){ //TODO:Addyourmessagehandlercodehereand/orcalldefault this->m_OrigPoint=point; CView::OnLButtonDown(nFlags,point);}voidCRectangleView::OnLButtonUp(UINTnFlags,CPointpoint){ //TODO:Addyourmessagehandlercodehereand/orcalldefault CClientDCdc(this);dc.Rectangle(CRect(m_OrigPoint,point)); CView::OnLButtonUp(nFlags,point);}5輸入輸出狀況及截圖6總結(jié)體會通過前期對VC++的學習和這次大作業(yè)，我對VC++有了進一步的相識，而且熟識了如何建立單文檔程序，多文檔等程序，對VisualC+
