MFC ListControl技巧汇总

转自:http://hi.baidu.com/qi_xian/blog/item/1971aa22da89ada24723e856.html

以下未经说明,listctrl默认view 风格为report
-------------------------------------------------------------------------------
1. CListCtrl 风格
LVS_ICON: 为每个item显示大图标
LVS_SMALLICON: 为每个item显示小图标
LVS_LIST: 显示一列带有小图标的item
LVS_REPORT: 显示item详细资料
直观的理解:windows资源管理器,"查看"标签下的"大图标,小图标,列表,详细资料
--------------------------------------------------------------------------------
2. 设置listctrl 风格及扩展风格
LONG lStyle;
lStyle = GetWindowLong(m_list.m_hWnd, GWL_STYLE);//获取当前窗口style
lStyle &= ~LVS_TYPEMASK; //清除显示方式位
lStyle |= LVS_REPORT; //设置style
SetWindowLong(m_list.m_hWnd, GWL_STYLE, lStyle);//设置style
DWORD dwStyle = m_list.GetExtendedStyle();
dwStyle |= LVS_EX_FULLROWSELECT;//选中某行使整行高亮(只适用与report风格的listctrl)
dwStyle |= LVS_EX_GRIDLINES;//网格线(只适用与report风格的listctrl)
dwStyle |= LVS_EX_CHECKBOXES;//item前生成checkbox控件
m_list.SetExtendedStyle(dwStyle); //设置扩展风格
注:listview的style请查阅msdn
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceshellui5/html/wce50lrflistviewstyles.asp
--------------------------------------------------------------------------------
3. 插入数据
m_list.InsertColumn( 0, "ID", LVCFMT_LEFT, 40 );//插入列
m_list.InsertColumn( 1, "NAME", LVCFMT_LEFT, 50 );

//新插入的在上面
int nRow = m_list.InsertItem(0, "11");// 插入行
m_list.SetItemText(nRow, 1, "jacky");//设置其它列数据

//新插入的数据在下面

int nIndex = m_list.GetItemCount();
LV_ITEM lvItem;
lvItem.mask = LVIF_TEXT ;
lvItem.iItem = nIndex; //行数
lvItem.iSubItem = 0;
lvItem.pszText = (char*)(LPCTSTR)strCount; //第一列
//在最后一行插入记录值.
m_list.InsertItem(&lvItem);
//插入其它列
m_list.SetItemText(nIndex,1,strLat);
--------------------------------------------------------------------------------
4. 一直选中item
选中style中的Show selection always,或者在上面第2点中设置LVS_SHOWSELALWAYS
--------------------------------------------------------------------------------
5. 选中和取消选中一行
int nIndex = 0;
//选中
m_list.SetItemState(nIndex, LVIS_SELECTED|LVIS_FOCUSED, LVIS_SELECTED|LVIS_FOCUSED);
//取消选中
m_list.SetItemState(nIndex, 0, LVIS_SELECTED|LVIS_FOCUSED);
--------------------------------------------------------------------------------
6. 得到listctrl中所有行的checkbox的状态
m_list.SetExtendedStyle(LVS_EX_CHECKBOXES);
CString str;
for(int i=0; i
{
if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED || m_list.GetCheck(i))
{
str.Format(_T("第%d行的checkbox为选中状态"), i);
AfxMessageBox(str);
}
}
--------------------------------------------------------------------------------
7. 得到listctrl中所有选中行的序号
方法一:
CString str;
for(int i=0; i
{
if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED )
{
str.Format(_T("选中了第%d行"), i);
AfxMessageBox(str);
}
}
方法二:
POSITION pos = m_list.GetFirstSelectedItemPosition();
if (pos == NULL)
TRACE0("No items were selected!/n");
Else
{
while (pos)
{
int nItem = m_list.GetNextSelectedItem(pos);
TRACE1("Item %d was selected!/n", nItem);
// you could do your own processing on nItem here
}
}
--------------------------------------------------------------------------------
8. 得到item的信息
TCHAR szBuf[1024];
LVITEM lvi;
lvi.iItem = nItemIndex;
lvi.iSubItem = 0;
lvi.mask = LVIF_TEXT;
lvi.pszText = szBuf;
lvi.cchTextMax = 1024;
m_list.GetItem(&lvi);
关于得到设置item的状态,还可以参考msdn文章
Q173242: Use Masks to Set/Get Item States in ClistCtrl
http://support.microsoft.com/kb/173242/en-us
--------------------------------------------------------------------------------
9. 得到listctrl的所有列的header字符串内容
LVCOLUMN lvcol;
char str[256];
int nColNum;
CString strColumnName[4];//假如有4列
nColNum = 0;
lvcol.mask = LVCF_TEXT;
lvcol.pszText = str;
lvcol.cchTextMax = 256;
while(m_list.GetColumn(nColNum, &lvcol))
{
strColumnName[nColNum] = lvcol.pszText;
nColNum++;
}
--------------------------------------------------------------------------------
10. 使listctrl中一项可见,即滚动滚动条
m_list.EnsureVisible(i, FALSE);
--------------------------------------------------------------------------------
11. 得到listctrl列数
int nHeadNum = m_list.GetHeaderCtrl()->GetItemCount();
--------------------------------------------------------------------------------
12. 删除所有列
方法一:
while ( m_list.DeleteColumn (0))
因为你删除了第一列后,后面的列会依次向上移动。
方法二:
int nColumns = 4;
for (int i=nColumns-1; i>=0; i--)
m_list.DeleteColumn (i);

删除所有行
直接用第7点的方法得到所有选中的行号,然后用DeleteItem(i)想删除所有行,这样是行不通的。因为ListCtrl的行号是从上往下排列的,你删除了上面的行后,下面的行号也随之改变,所以用此方法无法删除所有行。正确的方法是从下往上删除行。如下所示:
for(int i=m_list.GetItemCount()-1; i>=0;i--)
{
if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED )
{
m_list.DeleteItem(i);
}
}
--------------------------------------------------------------------------------
13. 得到单击的listctrl的行列号
添加listctrl控件的NM_CLICK消息相应函数
void CTest6Dlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)
{
// 方法一:

// 方法二:

*pResult = 0;
}
--------------------------------------------------------------------------------
14. 判断是否点击在listctrl的checkbox上
添加listctrl控件的NM_CLICK消息相应函数
void CTest6Dlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)
{
DWORD dwPos = GetMessagePos();
CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
m_list.ScreenToClient(&point);
LVHITTESTINFO lvinfo;
lvinfo.pt = point;
lvinfo.flags = LVHT_ABOVE;
UINT nFlag;
int nItem = m_list.HitTest(point, &nFlag);
//判断是否点在checkbox上
if(nFlag == LVHT_ONITEMSTATEICON)
{
AfxMessageBox("点在listctrl的checkbox上");
}
*pResult = 0;
}
--------------------------------------------------------------------------------
15. 右键点击listctrl的item弹出菜单
添加listctrl控件的NM_RCLICK消息相应函数
void CTest6Dlg::OnRclickList1(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
if(pNMListView->iItem != -1)
{
DWORD dwPos = GetMessagePos();
CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
CMenu menu;
VERIFY( menu.LoadMenu( IDR_MENU1 ) );
CMenu* popup = menu.GetSubMenu(0);
ASSERT( popup != NULL );
popup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y, this );
}
*pResult = 0;
}

16. item切换焦点时(包括用键盘和鼠标切换item时),状态的一些变化顺序
添加listctrl控件的LVN_ITEMCHANGED消息相应函数
void CTest6Dlg::OnItemchangedList1(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
// TODO: Add your control notification handler code here
CString sTemp;
if((pNMListView->uOldState & LVIS_FOCUSED) == LVIS_FOCUSED && (pNMListView->uNewState & LVIS_FOCUSED) == 0)
{
sTemp.Format("%d losted focus",pNMListView->iItem);
}
else if((pNMListView->uOldState & LVIS_FOCUSED) == 0 &&
(pNMListView->uNewState & LVIS_FOCUSED) == LVIS_FOCUSED)
{
sTemp.Format("%d got focus",pNMListView->iItem);
}
if((pNMListView->uOldState & LVIS_SELECTED) == LVIS_SELECTED &&
(pNMListView->uNewState & LVIS_SELECTED) == 0)
{
sTemp.Format("%d losted selected",pNMListView->iItem);
}
else if((pNMListView->uOldState & LVIS_SELECTED) == 0 && (pNMListView->uNewState & LVIS_SELECTED) == LVIS_SELECTED)
{
sTemp.Format("%d got selected",pNMListView->iItem);
}
*pResult = 0;

(WPARAM)LVSIL_NORMAL, (LPARAM)himlLarge);
}
return TRUE; // return TRUE unless you set the focus to a control
}

void CTest6Dlg::AddFiles(LPCTSTR lpszFileName, BOOL bAddToDocument)
{
int nIcon = GetIconIndex(lpszFileName, FALSE, FALSE);
CString strSize;
CFileFind filefind;

// get file size
if (filefind.FindFile(lpszFileName))
{
filefind.FindNextFile();
strSize.Format("%d", filefind.GetLength());
}
else
strSize = "0";

// split path and filename
CString strFileName = lpszFileName;
CString strPath;

int nPos = strFileName.ReverseFind('//');
if (nPos != -1)
{
strPath = strFileName.Left(nPos);
strFileName = strFileName.Mid(nPos + 1);
}

// insert to list
int nItem = m_list.GetItemCount();
m_list.InsertItem(nItem, strFileName, nIcon);
m_list.SetItemText(nItem, 1, strSize);
m_list.SetItemText(nItem, 2, strFileName.Right(3));
m_list.SetItemText(nItem, 3, strPath);
}

int CTest6Dlg::GetIconIndex(LPCTSTR lpszPath, BOOL bIsDir, BOOL bSelected)
{
SHFILEINFO sfi;
memset(&sfi, 0, sizeof(sfi));

if (bIsDir)
{
SHGetFileInfo(lpszPath,
FILE_ATTRIBUTE_DIRECTORY,
&sfi,
sizeof(sfi),
SHGFI_SMALLICON | SHGFI_SYSICONINDEX |
SHGFI_USEFILEATTRIBUTES |(bSelected ? SHGFI_OPENICON : 0));
return sfi.iIcon;
}
else
{
SHGetFileInfo (lpszPath,
FILE_ATTRIBUTE_NORMAL,
&sfi,
sizeof(sfi),
SHGFI_SMALLICON | SHGFI_SYSICONINDEX |
SHGFI_USEFILEATTRIBUTES | (bSelected ? SHGFI_OPENICON : 0));
return sfi.iIcon;
}
return -1;
}

处理NM_CUSTOMDRAW
http://www.codeproject.com/listctrl/lvcustomdraw.asp

 

//--------------------------------------------------------------------------------------------------------

开发环境:visual studio 2008 sp1

1、新建一个基于对话框的MFC应用程序。在对话框上拖放一个listcontrol控件和一个button控件,给listcontrol控件添加一个名为m_StoreItems的变量。添加button的点击响应函数。

void CDepartmentStoreDlg::OnBnClickedNewitem()

{

          // TODO: 在此添加控件通知处理程序代码

          srand((unsigned)time(NULL));

          TCHAR strNumber[20];//这里不要定义为char或者CString类型,不然后面 lvItem.pszText会报错。

          int number1 = rand() % 100;

          int number2 = rand() % 100;

          wsprintf(strNumber,_T("%d-%d"), number1, number2);

          LVITEM lvItem;

          lvItem.mask = LVIF_TEXT;

          lvItem.iItem = 0;

          lvItem.iSubItem = 0;

          lvItem.pszText = strNumber;

          m_StoreItems.InsertItem(&lvItem);

}

运行效果如下,效果相当于listbox控件,就是一个列表,一行一行的:

现在设置为报表视图,显示成表格形式。

在初始化函数里添加:

BOOL CDepartmentStoreDlg::OnInitDialog()

{

          CDialog::OnInitDialog();

             // TODO: 在此添加额外的初始化代码

          m_StoreItems.SetView(LVS_REPORT);//如果在属性里面设置了listview的view是report,这里就没必要了,默认的是icon

          LVCOLUMN lvColumn;

          lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;    //掩码设置了fmt值、显示列标题和指定宽度

          lvColumn.fmt = LVCFMT_LEFT;                     //设置作对其模式

          lvColumn.cx = 120;                                         //设置标题的宽度为120个像素

          lvColumn.pszText = _T("Full Name");             //设置标题(列名)

          m_StoreItems.InsertColumn(0, &lvColumn);   //添加列,索引为0

          lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;

          lvColumn.fmt = LVCFMT_LEFT;

          lvColumn.cx = 100;

          lvColumn.pszText = _T("Profession");

          m_StoreItems.InsertColumn(1, &lvColumn);

          lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;

          lvColumn.fmt = LVCFMT_LEFT;

          lvColumn.cx = 80;

          lvColumn.pszText = _T("Fav Sport");

          m_StoreItems.InsertColumn(2, &lvColumn);

          lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;

          lvColumn.fmt = LVCFMT_LEFT;

          lvColumn.cx = 75;

          lvColumn.pszText = _T("Hobby");

          m_StoreItems.InsertColumn(3, &lvColumn);

}

下面给报表添加点实际的内容。

继续在初始化函数里添加:

LVITEM lvItem;

int nItem;

lvItem.mask = LVIF_TEXT;//这里的掩码设置一定要注意,因为item和column的掩码值很像,例如LVIF_TEXT和LVCF_TEXT,I对应的item,C对应的column,不然的话会显示不出来的,这个地方害死我了,因为有插件自动补全代码,补全后没注意看,结果没有对应,郁闷了好一会

lvItem.iItem = 0;//行号(索引,从0开始),报表相当于二维数组的模式,添加行内容时要指定行号和列号

lvItem.iSubItem = 0;//列号(索引,从0开始)

lvItem.pszText = _T("Sandra C. Anschwitz");//内容

nItem = m_StoreItems.InsertItem(&lvItem);//插入这一行,返回行号(索引)

m_StoreItems.SetItemText(nItem, 1, _T("Singer"));//设置行索引(行号)和列索引(列号)的值

m_StoreItems.SetItemText(nItem, 2, _T("HandBall"));

m_StoreItems.SetItemText(nItem, 3, _T("Beach"));

lvItem.mask = LVIF_TEXT;

lvItem.iItem = 1;

lvItem.iSubItem = 0;

lvItem.pszText = _T("Roger A. Miller");

nItem = m_StoreItems.InsertItem(&lvItem);

m_StoreItems.SetItemText(nItem, 1, _T("Footballer"));

m_StoreItems.SetItemText(nItem, 2, _T("Tennis"));

m_StoreItems.SetItemText(nItem, 3, _T("Teaching"));

lvItem.mask = LVIF_TEXT;

lvItem.iItem = 2;

lvItem.iSubItem = 0;

lvItem.pszText = _T("Marie-Julie W. Gross");

nItem = m_StoreItems.InsertItem(&lvItem);

m_StoreItems.SetItemText(nItem, 1, _T("Student"));

m_StoreItems.SetItemText(nItem, 2, _T("Boxing"));

m_StoreItems.SetItemText(nItem, 3, _T("Programming"));

lvItem.mask = LVIF_TEXT;

lvItem.iItem = 3;

lvItem.iSubItem = 0;

lvItem.pszText = _T("Ella Pius Roger");

nItem = m_StoreItems.InsertItem(&lvItem);

m_StoreItems.SetItemText(nItem, 1, _T("Architect"));

m_StoreItems.SetItemText(nItem, 2, _T("Ping-Pong"));

m_StoreItems.SetItemText(nItem, 3, _T("Songo"));

中途小结:

在报表视图中,要做的主要有下面几步:

1)确保当前视图为报表视图,在属性窗口设置view或者在代码中设置为view模式

2)添加列:用到的数据结构是LVCOLUMN (就是list view column,对应的掩码也是LVCF_,list view column format)

3)添加行:用到的数据结构是LVITEM      (list view item,对应的掩码是LVIF_,list view item format)

           添加行的时候先添加第一个元素,即行索引为nItem,列索引为0,然后InsertItem,返回当前行的索引,之后就是设置该行的其他元素了,指定行、列索引和设置值即可。

4)删除行:BOOL DeleteItem(int nItem);删除指定的索引为nItem的行内容。有时候我们会先选中某行,然后删除,这个时候需要用到函数int GetNextItem(int nItem, int nFlags);从指定的索引nItem(不包括该索引,如果要包括该行的话,设置nItem -1即可)开始寻找满足nFlags条件的Item,成功则返回找到的Item的索引(如果有多个,则返回第一个),失败返回-1.这样的话如果要删除选中的某行,则可以这样实现 m_StoreItems.DeleteItem(m_StoreItems.GetNextItem(-1,LVNI_SELECTED));(建议设置扩展风格时,把整行选中设置进来this->m_StoreItems.SetExtendedStyle( LVS_EX_FULLROWSELECT);这样选中的时候就是一行了,否则会是一格)。如果要删除多行选中的,则可以用下面的代码:

int nIndex;

do

{

nIndex = m_StoreItems.GetNextItem(-1,LVNI_SELECTED);

m_StoreItems.DeleteItem(nIndex);

} while (nIndex != -1);

这里添加一点调整列宽的,以下代码可供参考(摘自CSDN):

voidCMyListView::AutoAdjustColumnWidth()

{

          CHeaderCtrl*pHeaderCtrl=m_pListCtrl->GetHeaderCtrl();

          m_pListCtrl->SetRedraw(FALSE);//防止闪烁

          pHeaderCtrl->SetRedraw(FALSE);//防止闪烁

          intnColumnCount=pHeaderCtrl->GetItemCount(); //获取列数

         for(inti=0; i<nColumnCount; i++)

          {

                 m_pListCtrl->SetColumnWidth(i, LVSCW_AUTOSIZE);

                 intnColumnWidth=m_pListCtrl->GetColumnWidth(i);

                 m_pListCtrl->SetColumnWidth(i, LVSCW_AUTOSIZE_USEHEADER);

                 intnHeaderWidth=m_pListCtrl->GetColumnWidth(i);

                 m_pListCtrl->SetColumnWidth(i, max(nColumnWidth, nHeaderWidth)+10);

          }

          pHeaderCtrl->SetRedraw(TRUE);//此处开启刷新,避免闪烁

          m_pListCtrl->SetRedraw(TRUE);

          pHeaderCtrl->Invalidate();//Update Window to redraw.

          pHeaderCtrl->UpdateWindow();

}

下面就开始设置图片了。

新建两个bitmap资源,大小为16*16,ID分别为IDB_UP和IDB_LOSANGE,初始化函数CDepartmentStoreDlg::OnInitDialog()改为如下:

m_StoreItems.SetView(LVS_REPORT);

LVCOLUMN lvColumn;

CBitmap bmpUP, bmpLosange;

bmpUP.LoadBitmap(IDB_UP);

bmpLosange.LoadBitmap(IDB_LOSANGE);

CImageList *ImgHeaders = new CImageList();

ImgHeaders->Create(16, 16, ILC_MASK, 1, 1);

ImgHeaders->Add(&bmpUP, RGB(0, 0, 0));

ImgHeaders->Add(&bmpLosange, RGB(0, 0, 0));

m_StoreItems.SetImageList(ImgHeaders, LVSIL_SMALL);

lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH | LVCF_IMAGE;

lvColumn.fmt = LVCFMT_LEFT | LVCFMT_IMAGE;

lvColumn.cx = 120;

lvColumn.pszText = _T("Full Name");

lvColumn.iImage = 0;

m_StoreItems.InsertColumn(0, &lvColumn);

lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;

lvColumn.fmt = LVCFMT_LEFT;

lvColumn.cx = 100;

lvColumn.pszText = _T("Profession");

m_StoreItems.InsertColumn(1, &lvColumn);

lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH | LVCF_IMAGE;

lvColumn.fmt = LVCFMT_LEFT | LVCFMT_IMAGE;

lvColumn.iImage = 1;

lvColumn.cx = 80;

lvColumn.pszText = _T("Fav Sport");

m_StoreItems.InsertColumn(2, &lvColumn);

lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;

lvColumn.fmt = LVCFMT_LEFT;

lvColumn.cx = 75;

lvColumn.pszText = _T("Hobby");

m_StoreItems.InsertColumn(3, &lvColumn);


继续完善。给CDepartmentStoreDlg类添加变量:

CImageList m_SmallImg;

CImageList m_LargeImg;

函数:

DWORD GetViewType(void);

void SetViewType(DWORD dwViewType);

cpp中的实现:

DWORD CDepartmentStoreDlg::GetViewType(void)

{

             return (GetStyle() & LVS_TYPEMASK);

}

void CDepartmentStoreDlg::SetViewType(DWORD dwViewType)

{

             DWORD dwCurType;

             HWND hWnd;

             hWnd = this->m_StoreItems;

            GetSafeHwnd();

            dwCurType = ::GetWindowLong(hWnd, GWL_STYLE);

            dwCurType &= ~LVS_TYPEMASK;

            dwViewType |= dwCurType;

           ::SetWindowLong(hWnd, GWL_STYLE, dwViewType);

}

窗体上添加Large、Small、List、Details四个button,添加鼠标点击事件的响应函数,如下:

void CDepartmentStoreDlg::OnBnClickedLarge()

{

         // TODO: 在此添加控件通知处理程序代码

           SetViewType(LVS_ICON);

}

void CDepartmentStoreDlg::OnBnClickedSmall()

{

             // TODO: 在此添加控件通知处理程序代码

              if( GetViewType() != LVS_SMALLICON)

                     SetViewType(LVS_SMALLICON);

}

void CDepartmentStoreDlg::OnBnClickedDetail()

{

            // TODO: 在此添加控件通知处理程序代码

              if( GetViewType() != LVS_REPORT)

                      SetViewType(LVS_REPORT);

}

void CDepartmentStoreDlg::OnBnClickedList()

{

             // TODO: 在此添加控件通知处理程序代码

            if( GetViewType() != LVS_LIST)

                      SetViewType(LVS_LIST);

}

窗体上的New Item按钮调用的窗体如下,用来添加数据, 给窗体创建类,并给控件添加相应变量。

添加2个位图资源,属性为ID:IDB_Larging Weight:162 Height:32,ID:IDB_Smalling Weight:80 Height:16


初始化函数代码:

m_StoreItems.SetView(LVS_REPORT);

LVCOLUMN lvColumn;

lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;

lvColumn.fmt = LVCFMT_CENTER;

lvColumn.cx = 60;

lvColumn.pszText = _T("Item #");

this->m_StoreItems.InsertColumn(0, &lvColumn);

lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;

lvColumn.fmt = LVCFMT_LEFT;

lvColumn.cx = 100;

lvColumn.pszText = _T("Category");

this->m_StoreItems.InsertColumn(1, &lvColumn);

lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;

lvColumn.fmt = LVCFMT_LEFT;

lvColumn.cx = 160;

lvColumn.pszText = _T("Item Name");

this->m_StoreItems.InsertColumn(2, &lvColumn);

lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;

lvColumn.fmt = LVCFMT_LEFT;

lvColumn.cx = 80;

lvColumn.pszText = _T("Size");

this->m_StoreItems.InsertColumn(3, &lvColumn);

lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;

lvColumn.fmt = LVCFMT_RIGHT;

lvColumn.cx = 60;

lvColumn.pszText = _T("Unit Price");

this->m_StoreItems.InsertColumn(4, &lvColumn);

lvColumn.mask = LVCF_FMT | LVCF_TEXT | LVCF_WIDTH;

lvColumn.fmt = LVCFMT_RIGHT;

lvColumn.cx = 30;

lvColumn.pszText = _T("Qty");

this->m_StoreItems.InsertColumn(5, &lvColumn);

this->m_StoreItems.SetExtendedStyle(LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES);//设置扩展风格

m_SmallImg.Create(IDB_Smalling, 16, 1, RGB(255, 255, 255));

m_LargeImg.Create(IDB_Larging, 32, 1, RGB(255, 255, 245));

m_StoreItems.SetImageList(&m_SmallImg, LVSIL_SMALL);

m_StoreItems.SetImageList(&m_LargeImg, LVSIL_NORMAL);

New Item按钮的响应函数为(将添加item的类include进来):

void CDepartmentStoreDlg::OnBnClickedNewitem()

{

        // TODO: 在此添加控件通知处理程序代码

         CNewItemDlg dlg;//这个是添加新数据的窗体类

         srand((unsigned)time(NULL));

        TCHAR strNumber[20];

        int number1 = rand() % 100;

        int number2 = rand() % 100;

        wsprintf(strNumber,_T("%d-%d"), number1, number2);

        dlg.m_ItemNumber = strNumber;

         if (dlg.DoModal())

        {

                LVITEM lvItem;

               int nItem;

               int imgNbr;

              if( dlg.m_Category == "Babies" )

                      imgNbr = 0;

              else if( dlg.m_Category == "Teens" )

                     imgNbr = 1;

              else if( dlg.m_Category == "Women" )

                     imgNbr = 2;

             else if( dlg.m_Category == "Men" )

                     imgNbr = 3;

             else

                    imgNbr = 4;

            lvItem.mask = LVIF_IMAGE | LVIF_TEXT;

            lvItem.iItem = 0;

            lvItem.iSubItem = 0;

            lvItem.pszText = strNumber;

            lvItem.iImage = imgNbr;

            nItem = this->m_StoreItems.InsertItem(&lvItem);

            this->m_StoreItems.SetItemText(nItem, 1, dlg.m_Category);

            this->m_StoreItems.SetItemText(nItem, 2, dlg.m_ItemName);

            this->m_StoreItems.SetItemText(nItem, 3, dlg.m_ItemSize);

            this->m_StoreItems.SetItemText(nItem, 4, dlg.m_UnitPrice);

            this->m_StoreItems.SetItemText(nItem, 5, dlg.m_Quantity);

        }

}
