MFC課程設(shè)計之調(diào)色板

1、mfc課程設(shè)計說明書設(shè)計題目：綜合調(diào)色板 所屬系部： 計算機工程系 專 業(yè)： 軟件工程 學(xué) 號： 102056238 姓 名： 設(shè)計日期：2011-11-28 1. 設(shè)計描述通過綜合這學(xué)期的知識，最終做了個調(diào)色板。首先，此調(diào)色板可以通過控制紅，綠，藍(lán)三個滑塊控件來使列表框的顏色隨之變化；也可以通過點擊顏色板來自己選取想要顯示的顏色。其次，當(dāng)關(guān)閉調(diào)色板時有對話框提示，既可以最小化到托盤，也可以直接退出程序，同時可以通過操作注冊表來操作。最后，此調(diào)色板應(yīng)用了皮膚設(shè)置，使之看起來更美化！2設(shè)計分析主要函數(shù)及聲明：void writeregistry();void readregistry();voi

3、string str;其他新添加的函數(shù)消息： void onhscroll(uint nsbcode, uint npos, cscrollbar* pscrollbar);void onabout();void onexit();void onopen();void onclose();void ondestroy();其中，有一個函數(shù)比較特殊，需手動添加，在colordlg.h中添加void ontraynotify(wparam wparam, lparam lparam);在colordlg.cpp中afx_msg_map(ccolordlg)與 afx_msg_map之間添加on_m

4、essage(wm_icon_notify, ontraynotify)，最后在colordlg.cpp中手動添加函數(shù)：void ccolordlg:ontraynotify(wparam wparam, lparam lparam)在資源視圖中需要做的工作有：引入兩個對話框，分別添加相應(yīng)的控件，并定義其成員變量。紅綠藍(lán)控件id分別命名為idc_scrollbar_red，idc_slider_green，idc_slider_blue，編輯框命名為idc_list_box，清除注冊信息命名為idc_registry。對話框成員變量： cscrollbarm_scrollred;cslider
