windows程序设计实验报告模板 副本 一、实验目的 一、实验目的掌握用C/C+语言采用API在Windows平台下编写软件的方法，熟悉消息驱动的本质；熟悉Windows平台基本控件的本质、熟悉动态链接库的使用，加深对课堂知识的掌握。 二、实验内容仿照Windows操作系统附件的绘图软件设计一个绘图程序，依次为程序增加绘图函数、菜单选择、工具选择、颜色选择、文件操作等功能，可以在此基础上进行扩充，最终完成一个相对完整的绘图程序。 三、功能分析1.实现曲线，直线，矩形，椭圆图形的绘制；2.实现图形线条宽度，颜色的改变以及矩形和椭圆的填充；3.对绘制图形的保存以及，对以保存的文件的打开和另存；4.清屏功能。 四、窗口窗口类对应的处理函数szWindowClass（主窗口）WndProc()szDrawWndClass（工作区窗口）WndDrawProc()szColorBoxClass（颜色选择窗口）ColorBoxProc()szToolBtnClass（工具选择窗口）ToolBtWndProc()szToolboxClass（工具栏窗口）ToolboxWndProc()Windows程序设计实验报告3 五、模块分解根据程序运行时的操作来划分，本程序可大致分为三大功能模块，分别为调色板，工具箱，工作区绘图，如下1调色板模块本模块用来提供绘图时的颜色的选择，并将改变后的颜色显示在调色板颜色示例的矩形区域中。 2工具箱模块本模块用来提供绘图时工具的选择，当选择了某一工具后，该工具按钮是选中状态，其他按钮是凸起状态。 3工作区绘图模块本模块用来提供鼠标完成各种图形的绘制的区域。 2.主窗口 一、菜单的创建case WM_MAND:wmId=LOWORD(wParam);wmEvent=HIWORD(wParam);/Parse themenu selections:switch(wmId)case IDM_ABOUT:DialogBox(hInst,(LPCTSTR)IDD_ABOUTBOX,hWnd,(DLGPROC)About);break;case IDM_EDIT_PENWIDTH:/把线的宽度传到对话框里if(DialogBoxParam(hInst,(LPCTSTR)IDD_DLG_PENWIDTH,hWnd,(DLGPROC)DlgPenWidth,(LPARAM)&iPenWidth)=IDOK)SendMessage(hWndDraw,WM_CHANGEPENWIDTH,(WPARAM)0,(LPARAM)iPenWidth);break;case IDM_VIEW_COLOR:/如果颜色被选中则显示，如果不被选中则不显示if(IsWindowVisible(hWndColor)Windows程序设计实验报告4ShowWindow(hWndColor,SW_HIDE);CheckMenuItem(hMenu,IDM_VIEW_COLOR,MF_BYMAND|MF_UNCHECKED);elseShowWindow(hWndColor,SW_SHOWNORMAL);CheckMenuItem(hMenu,IDM_VIEW_COLOR,MF_BYMAND|MF_CHECKED);break;case IDM_VIEW_TOOLS:/如果工具被选中则显示，如果不被选中则不显示if(IsWindowVisible(Tb.hwndToolbox)ShowWindow(Tb.hwndToolbox,SW_HIDE);CheckMenuItem(hMenu,IDM_VIEW_TOOLS,MF_BYMAND|MF_UNCHECKED);elseShowWindow(Tb.hwndToolbox,SW_SHOWNORMAL);CheckMenuItem(hMenu,IDM_VIEW_TOOLS,MF_BYMAND|MF_CHECKED);break;case IDM_FILE_NEW:/新建SendMessage(hWndDraw,message,wParam,lParam);break;case IDM_FILE_OPEN:/打开SendMessage(hWndDraw,message,wParam,lParam);break;case IDM_FILE_SAVE:/保存SendMessage(hWndDraw,message,wParam,lParam);break;case IDM_FILE_SAVEAS:/另存为SendMessage(hWndDraw,message,wParam,lParam);break;Windows程序设计实验报告5case IDM_EDIT_CLEAR:/清空/MessageBox(hWnd,TEXT(INMain),TEXT(Msg),MB_OK);SendMessage(hWndDraw,message,wParam,lParam);break;case IDM_EXIT:SendMessage(hWnd,WM_CLOSE,(WPARAM)0,(LPARAM)0);break;default:return DefWindowProc(hWnd,message,wParam,lParam);break;
