簡單畫圖板設計報告1. 設計目的：設計一個能夠自定義顏色；能夠實現(xiàn)自定義字體的大小顏色并且輸出到畫圖板上；能夠實現(xiàn)簡單的圖形繪制（如：直線；矩形；橢圓；圓角矩形等）；能夠實現(xiàn)鉛筆功能來實現(xiàn)連續(xù)畫線；能夠實現(xiàn)自定義線寬和自定義線型；能夠實現(xiàn)畫刷和局部填充顏色；能夠實現(xiàn)實現(xiàn)清屏功能和計時的附加功能。2.總體設計：簡單畫圖板圖 形直線矩形橢圓鉛筆畫線圓角矩形餅圖線寬線寬為2線寬為3線寬為5自定義線寬顏色紅藍綠自定義顏色線型自定義線型畫刷文字調用文字附加功能清屏秒表3詳細設計：CMyView 顏色類型：COLORREF; 線寬類型:int; 線型類型：int; 坐標點類型：CPOINT;輸出字體類型：Cstring；void CMyView:OnDelete()；void CMyView:OnDline()；void CMyView:OnDraw(CDC* pDC);voidCMyView:OnEllipse();voidCMyView:OnFillcolor();voidCMyView:OnLButtonDown(UINTnFlags,Cpointpoint);voidCMyView:OnLButtonUp(UINT nFlags, CPoint point); void CMyView:OnLine();void CMyView:OnMouseMove(UINT nFlags, CPoint point);voidCMyView:OnMyfont();voidCMyView:OnPie();voidCMyView:OnRectangle();voidCMyView:OnRoundrectangle();voidCMyView:OnUserdefined();voidCMyView:OnUserdefinedbrush();voidCMyView:OnUserdifinedColor();voidCMyView:OnUserdifinedLinewidth();BOOL CMyView:PreCreateWindow(CREATESTRUCT& cs);MYFONT顏色類型：COLORREF；顏色列表：CListBox編輯框變量：Cstring類型選擇列表：int;voidMYFONT:OnCancelMode();void MYFONT:OnChangeDataEdit();void MYFONT:OnExitButton();BOOL MYFONT:OnInitDialog();voidMYFONT:OnPaint();voidMYFONT:OnRadio();voidMYFONT:OnSetButton();CtimerDlg時間變量：int;時間變量m_nTimer:UINT;傳遞變量m_timer:Cstring;CTimerDlg:CTimerDlg(CWnd*pParent )CDialog(CTimerDlg:IDD, pParent); void CTimerDlg:DoDataExchange(CDataExchange* pDX); void CTimerDlg:OnBeginTime();voidCTimerDlg:OnCancle();void CTimerDlg:OnEndTime();voidCTimerDlg:OnTimer(UINTnIDEvent);父類ClineWidthCLineWidth:CLineWidth(CWnd* pParent)CDialog(CLineWidth:IDD, pParent)；voidCLineWidth:DoDataExchange(CDataExchange*pDX);voidCLineWidth:OnOK;ClineStyleCLineStyle:CLineStyle(CWnd* pParent)CDialog(CLineStyle:IDD, pParent);voidCLineStyle:DoDataExchange(CDataExchange*pDX);voidCLineStyle:OnCancel();voidCLineStyle:OnLinestyle();void CLineStyle:OnOK();4測試過程:先進行了基本圖形的繪制，然后測試圖形的顏色，線寬，線型，畫刷填充，文字顯示，位圖載入，上述功能基本都能實現(xiàn)。最后測試清屏，橡皮圖形重繪等功能，遇到了一些問題。測試遇到問題：1.窗口不能重繪。2.清屏后不能重繪。解決問題方法：1.在OnDraw函數(shù)中加入一個Point數(shù)組，把已經(jīng)畫過的保存起來。 2.將畫圖選擇變量select設-1，調用Invalidate();這樣在清屏后還可調用OnDraw函數(shù)進行畫圖。5源程序清單和執(zhí)行結果：1我的畫圖板加強版.cpp:#include stdafx.h#include 我的畫圖板加強版.h#include MainFrm.h#include 我的畫圖板加強版Doc.h#include 我的畫圖板加強版View.h#ifdef _DEBUG#define new DEBUG_NEW#undef THIS_FILEstatic char THIS_FILE = _FILE_;#endif/ CMyAppBEGIN_MESSAGE_MAP(CMyApp, CWinApp)/AFX_MSG_MAP(CMyApp)ON_COMMAND(ID_APP_ABOUT, OnAppAbout)/ NOTE - the ClassWizard will add and remove mapping macros here./ DO NOT EDIT what you see in these blocks of generated code!/AFX_MSG_MAP/ Standard file based document commandsON_COMMAND(ID_FILE_NEW, CWinApp:OnFileNew)ON_COMMAND(ID_FILE_OPEN, CWinApp:OnFileOpen)/ Standard print setup commandON_COMMAND(ID_FILE_PRINT_SETUP, CWinApp:OnFilePrintSetup)END_MESSAGE_MAP()/ CMyApp constructionCMyApp:CMyApp()/ TODO: add construction code here,/ Place all significant initialization in InitInstance/ The one and only CMyApp objectCMyApp theApp;/ CMyApp initializationBOOL CMyApp:InitInstance()AfxEnableControlContainer();/ Standard initialization/ If you are not using these features and wish to reduce the size/ of your final executable, you should remove from the following/ the specific initialization routines you do not need.#ifdef _AFXDLLEnable3dControls();/ Call this when using MFC in a shared DLL#elseEnable3dControlsStatic();/ Call this when linking to MFC statically#endif/ Change the registry key under which our settings are stored./ TODO: You should modify this string to be something appropriate/ such as the name of your company or organization.SetRegistryKey(_T(Local AppWizard-Generated Applications);LoadStdProfileSettings(); / Load standard INI file options (including MRU)/ Register the applications document templates.
