1.前言
最近发现读者对我的mfc美化的专栏比较感兴趣，因此在这里进行续写，这里我会计划写几个连续的篇章，包括对MFC按钮的美化，菜单栏的美化，标题栏的美化，list列表的美化，直到最后形成一个完整的成品效果。
2.最终效果展示
3.思路分析
1.编写mfc的list的派生类对 列表进行重绘
2.list和其他的空间有些区别，要分别对标题栏，和内容栏进行重绘。
4.实现的过程
1.在mfc界面，增加空间list
2.修改list的属性
边框:false
静态边缘：false
视图:Reporte
无滚动：true
3.声明list的变量
public: CListCtrlComboEx m_list;
4.OnInitDialog 里面的核心代码
BOOL CCustomListDlg::OnInitDialog()
{
CDialogEx::OnInitDialog();
// 将“关于...”菜单项添加到系统菜单中。
// IDM_ABOUTBOX 必须在系统命令范围内。
ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
ASSERT(IDM_ABOUTBOX AppendMenu(MF_SEPARATOR);
pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
}
}
// 设置此对话框的图标。 当应用程序主窗口不是对话框时，框架将自动
// 执行此操作
SetIcon(m_hIcon, TRUE); // 设置大图标
SetIcon(m_hIcon, FALSE); // 设置小图标
//LIST
CRect rect;
m_list.GetClientRect(&rect);
DWORD dwStyle = m_list.GetExtendedStyle();
//dwStyle = (dwStyle | LVS_EX_GRIDLINES | LVS_EX_FULLROWSELECT | LVS_EX_DOUBLEBUFFER);
dwStyle |= dwStyle | LVS_REPORT & ~LVS_EX_GRIDLINES | LVS_EX_FULLROWSELECT | LVS_SHOWSELALWAYS | LVS_EX_HEADERDRAGDROP;
m_list.SetExtendedStyle(dwStyle);
//m_list.SetBo
m_list.SetItemHeight(25);
m_list.SetFontSize(17);
m_list.InsertColumn(0, _T("编号"), LVCFMT_CENTER, (rect.Width() / 3) + 30, 0);
m_list.InsertColumn(1, _T("菜谱"), LVCFMT_CENTER, (rect.Width() - (rect.Width() / 3) - 30), 1);
m_list.InsertColumn(2, _T(""), LVCFMT_CENTER, 1000, 2);
m_list.InsertItem(0, _T("1"));
m_list.InsertItem(1, _T("2"));
m_list.InsertItem(2, _T("3"));
m_list.InsertItem(3, _T("4"));
m_list.InsertItem(4, _T("5"));
m_list.InsertItem(5, _T("6"));
m_list.InsertItem(6, _T("7"));
m_list.InsertItem(7, _T("8"));
m_list.InsertItem(8, _T("9"));
m_list.InsertItem(9, _T(""));
m_list.InsertItem(10, _T(""));
m_list.InsertItem(11, _T(""));
// TODO: 在此添加额外的初始化代码
return TRUE; // 除非将焦点设置到控件，否则返回 TRUE
