ListCtrl控件

一 CListCtrl类型

　　LVS_EDITLABELS   

　　LVS_OWNERDRAWFIXED

　　LVS_REPORT

　　LVS_SHOWSELALWAYS

　　LVS_SINGLESEL

　　LVS_SMALLICONw

　　LVS_SORTASCENDING LVS_SORTDESCENDING

　　LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES | LVS_EX_HEADERDRAGDROP

　　（1）添加或删除风格nStyle |= 或 nStyle &~

       （2）设置扩展风格GetExtendStyle(); SetExtendStyle(DWORD dwStyle);

二 动态创建带图标的ListCtrl控件

　　（1）Create　　

CListCtrlEx *pListCtrl = new CListCtrlEx();
 pListCtrl->Create(WS_VISIBLE|LVS_REPORT|LVS_OWNERDRAWFIXED, CRect(20,20,300,300), this, IDC_LISTCTRL);

　　（2）设置扩展风格GetExtendStyle()和GetExtendStyle()

DWORD nStyle = pListCtrl->GetExtendedStyle();
 nStyle |= LVS_EX_GRIDLINES|LVS_EX_FULLROWSELECT|LVS_EX_HEADERDRAGDROP;
 pListCtrl->SetExtendedStyle(nStyle);　

　　（3）初始化CImageList

CBitmap bmp1,bmp2;
bmp1.LoadBitmap(IDB_BITMAP1);
bmp2.LoadBitmap(IDB_BITMAP2);
m_ImageList.Create(16,16,ILC_COLOR32|ILC_MASK,4,4);
m_ImageList.Add(&bmp1, RGB(255,255,255));
m_ImageList.Add(&bmp2,RGB(255,255,255));
pListCtrl->SetImageList(&m_ImageList, LVSIL_SMALL);

　　（4）插入列，行

pListCtrl->InsertColumn(0, "学号",LVCFMT_LEFT, 100);
pListCtrl->InsertColumn(1, "姓名",LVCFMT_LEFT,100);
pListCtrl->InsertColumn(2, "成绩",LVCFMT_LEFT,100);
// 方法1
pListCtrl->InsertItem(0, "1", 0);
pListCtrl->SetItemText(0,1,"张三");
pListCtrl->SetItemText(0,2,"100");
方法2
{
    LV_ITEM lvItem = {0};
    lvItem.mask = LVIF_TEXT|LVIF_IMAGE|LVIF_PARAM;
    lvItem.iItem = 1;
    lvItem.iSubItem = 0;
    lvItem.iImage = 1;
    lvItem.lParam = (LPARAM)0;
    lvItem.pszText="1";
    pListCtrl->InsertItem(&lvItem);
}
{
    LV_ITEM lvItem = {0};
    lvItem.mask = LVIF_TEXT;
    lvItem.iItem = 1;
    lvItem.iSubItem = 1;
    lvItem.lParam = 1;
    lvItem.pszText="张三";
    pListCtrl->SetItem(&lvItem);
}
{
    LV_ITEM lvItem = {0};
     lvItem.mask = LVIF_TEXT|LVIF_IMAGE;
    lvItem.iItem = 1;
    lvItem.iSubItem = 2;
    lvItem.iImage = 0;          // 特别测试该位置的iImage无效
    lvItem.pszText="100";
    pListCtrl->SetItem(&lvItem);
}
