VC++ List Control 的具体用法实例

1. ListCtrl 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

--------------------------------------------------------------------------------

3. 插入数据

m_list.InsertColumn( 0, "ID", LVCFMT_LEFT, 40 );//插入列

m_list.InsertColumn( 1, "NAME", LVCFMT_LEFT, 50 );

int nRow = m_list.InsertItem(0, “11”);//插入行

m_list.SetItemText(nRow, 1, “jacky”);//设置数据

--------------------------------------------------------------------------------

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<m_list.GetItemCount(); 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);

}

}

CString strIns;

strIns="delete from tmpStatByGround";

m_pRs.CreateInstance(__uuidof(Recordset));

m_pRs->CursorLocation = adUseClient;

m_pRs->Open((LPCTSTR)strIns, vDispatch, adOpenKeyset,

adLockOptimistic, adCmdUnknown);

--------------------------------------------------------------------------------

7. 得到listctrl中所有选中行的序号

方法一：

CString str;

for(int i=0; i<m_list.GetItemCount(); 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);

--------------------------------------------------------------------------------

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);

--------------------------------------------------------------------------------

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;

}

--------------------------------------------------------------------------------

17. listctrl的 subitem 添加图标

注意: 首先要用 InsertItem() 插入一行的第一列, 然后才能用 SetItem 设置其他项

m_list.SetExtendedStyle(LVS_EX_SUBITEMIMAGES);

m_userlist.SetItem(..);

--------------------------------------------------------------------------------

18. 在CListCtrl显示文件，并根据文件类型来显示图标

网上找到的代码，自己试用并改正过, share

步骤1: 设置 list 的图像列表为 系统图像列表

BOOL SetSystemImageList( CListCtrl & list )

{

HIMAGELIST himlSmall;

HIMAGELIST himlLarge;

SHFILEINFO sfi;

char cSysDir[MAX_PATH];

CString strBuf;

memset(cSysDir, 0, MAX_PATH);

GetWindowsDirectory(cSysDir, MAX_PATH);

strBuf = cSysDir ;

// SHGetFileInfo:

// If uFlags contains SHGFI_SYSICONINDEX, the return value is a handle to

// an image list that contains the large icon images.

// If SHGFI_SMALLICON is included with SHGFI_SYSICONINDEX, the return value

// is the handle to an image list that contains the small icon images.

//

himlSmall = (HIMAGELIST)SHGetFileInfo ( (LPCSTR)cSysDir,

0,

&sfi,

sizeof(SHFILEINFO),

SHGFI_SYSICONINDEX | SHGFI_SMALLICON );

himlLarge = (HIMAGELIST)SHGetFileInfo((LPCSTR)cSysDir,

0,

&sfi,

sizeof(SHFILEINFO),

SHGFI_SYSICONINDEX | SHGFI_LARGEICON);

if (himlSmall && himlLarge)

{

::SendMessage(list.m_hWnd, LVM_SETIMAGELIST,

(WPARAM)LVSIL_SMALL, (LPARAM)himlSmall);

::SendMessage(list.m_hWnd, LVM_SETIMAGELIST,

(WPARAM)LVSIL_NORMAL, (LPARAM)himlLarge);

}

return TRUE;

}

步骤2: 给列表添加指定的文件, 同时获得该文件的的图标索引, 给 list 添加图标

int GetIconIndex(LPCTSTR lpszPath, BOOL bIsDir, BOOL bSelected) ; // 向前声明

void AddFiles(CListCtrl & list, LPCTSTR lpszFileName, BOOL bAddToDocument)

{

int nIcon = GetIconIndex(lpszFileName, FALSE, TRUE);

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 = list.GetItemCount();

//list.InsertItem(nItem, strFileName, nIcon);

//list.SetItemText(nItem, 1, strSize);

//

// 此处可以根据实际需要修改代码

//

}

--------------------------------------------------------------------------------

19. listctrl内容进行大数据量更新时，避免闪烁

m_list.SetRedraw(FALSE);

//更新内容

m_list.SetRedraw(TRUE);

m_list.Invalidate();

m_list.UpdateWindow();

20. 清除 ListCtrl 以重新初始化:

// 删除所有行

m_ctrllist.DeleteAllItems() ;

// 删除所有列

int iColCount = m_ctrllist.GetHeaderCtrl()->GetItemCount() ;

// 方法 1

// 原理: 删除第一列后, 其他列向前移动

while( m_ctrllist.DeleteColumn(0) ) ;

// 方法 2

for (int i=0; i < iColCount ; i )

{

m_ctrllist.DeleteColumn(0);

}

// 方法 3

for (int i=iColCount-1; i >= 0; i-- )

{

m_ctrllist.DeleteColumn( i );

}
