MFC课程设计之调色板.doc

mfc课程设计说明书设计题目：综合调色板 所属系部： 计算机工程系 专 业： 软件工程 学 号： 102056238 姓 名： 设计日期：2011-11-28 1. 设计描述通过综合这学期的知识，最终做了个调色板。首先，此调色板可以通过控制红，绿，蓝三个滑块控件来使列表框的颜色随之变化；也可以通过点击颜色板来自己选取想要显示的颜色。其次，当关闭调色板时有对话框提示，既可以最小化到托盘，也可以直接退出程序，同时可以通过操作注册表来操作。最后，此调色板应用了皮肤设置，使之看起来更美化！2设计分析主要函数及声明：void writeregistry();void readregistry();void inquiry();bool modifytray(hwnd hwnd,uint uid);bool removetray(hwnd hwnd);bool addtray(hwnd hwnd,lpstr lpsztip);void ontimer(uint nidevent);void onregistry();ccolordlg(cwnd* pparent = null);crect listboxrect;/列表框区域int exitinstance()protected成员变量：hinstance hinstance;hicon m_hicon;int nradio,ncheck;cstring str;其他新添加的函数消息： void onhscroll(uint nsbcode, uint npos, cscrollbar* pscrollbar);void onabout();void onexit();void onopen();void onclose();void ondestroy();其中，有一个函数比较特殊，需手动添加，在colordlg.h中添加void ontraynotify(wparam wparam, lparam lparam);在colordlg.cpp中afx_msg_map(ccolordlg)与 afx_msg_map之间添加on_message(wm_icon_notify, ontraynotify)，最后在colordlg.cpp中手动添加函数：void ccolordlg:ontraynotify(wparam wparam, lparam lparam)在资源视图中需要做的工作有：引入两个对话框，分别添加相应的控件，并定义其成员变量。红绿蓝控件id分别命名为idc_scrollbar_red，idc_slider_green，idc_slider_blue，编辑框命名为idc_list_box，清除注册信息命名为idc_registry。对话框成员变量： cscrollbarm_scrollred;csliderctrlm_slidergreen;csliderctrlm_sliderblue;intm_nredvalue;intm_nblue;intm_ngreen;在资源视图中引入一个菜单资源和几个icon资源 3.运行界面启动界面蓝色调色对话框退出提示托盘图标菜单 托盘图标变化关于4.源代码/ colordlg.cpp : implementation file/#include stdafx.h#include color.h#include colordlg.h#ifdef _debug#define new debug_new#undef this_filestatic char this_file = _file_;#endif/ caboutdlg dialog used for app aboutclass caboutdlg : public cdialogpublic:caboutdlg();/ dialog data/afx_data(caboutdlg)enum idd = idd_aboutbox ;/afx_data/ classwizard generated virtual function overrides/afx_virtual(caboutdlg)protected:virtual void dodataexchange(cdataexchange* pdx);
