Windows程序设计实验报告

1.概述

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 szWindowClass（主窗口） szDrawWndClass（工作区窗口） szColorBoxClass（颜色选择窗口） szToolBtnClass（工具选择窗口） szToolboxClass（工具栏窗口） 对应的处理函数 WndProc() WndDrawProc() ColorBoxProc() ToolBtWndProc() ToolboxWndProc()

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_COMMAND:

wmId = LOWORD(wParam); wmEvent = HIWORD(wParam); // Parse the menu selections: switch (wmId) {

case IDM_ABOUT:

case IDM_EDIT_PENWIDTH://把线的宽度传到对话框里

} break;

if(IsWindowVisible(hWndColor))

(DLGPROC)DlgPenWidth,(LPARAM)&iPenWidth)==IDOK)

SendMessage(hWndDraw,WM_CHANGEPENWIDTH,(WPARAM)0,(LPARAM)iPenWidth);

case IDM_VIEW_COLOR://如果颜色被选中则显示，如果不被选中则不显示

6.实验总结

一、实验结果

二、感想体会

通过老师对windows程序设计的讲解和自己的学习，掌握了消息队列以及循环队列的知识，掌握了窗口消息的处理和响应，对windows API有了更深入的理解。

总的来说，这次学习收获还是很大的。这个程序通过老师一点一点的讲解，一点一点往里加东西，逐渐变成了一个大程序，相对于我以前编的代码，程序还是比较大的。让我对大程序有了一定的认识，对模块化编程有了一定的了解，不再那么害怕编程了，谢谢老师！

5.工具栏窗口和工具选择窗口 一、工具选择的实现

工具栏的每个图标对应两个位图，鼠标弹起和落下对应两个不同的位图。

for (i = 0; i < pTb->iToolBtnCount; i++) {

if (!(pTb->aTools[i].hbmToolBtnUp= LoadBitmap(pTb->hInst,

if (!(pTb->aTools[i].hbmToolBtnDown = LoadBitmap(pTb->hInst,

MAKEINTRESOURCE(pTb->aTools[i].idbmToolBtnDown)))) return;

28

MAKEINTRESOURCE(pTb->aTools[i].idbmToolBtnUp)))) return;

SendMessage(pTb->hWndWork,WM_TOOLCHANGE,(WPARAM)pTb,(LPARAM)0L);

//* Select the tool that was clicked on. pTb=(PTOOLBOX)GetWindowLong(hwnd,GWL_USERDATA);

ToolboxSelectTool(pTb,(UINT)GetWindowLong((hwnd), GWL_ID));

}
