MFC ListControl用法(转)

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<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);

}

}

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

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);

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);

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

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：

/*

DWORD dwPos = GetMessagePos();

CPoint point( LOWORD(dwPos), HIWORD(dwPos) );

m_list.ScreenToClient(&point);

LVHITTESTINFO lvinfo;

lvinfo.pt = point;

lvinfo.flags = LVHT_ABOVE;

int nItem = m_list.SubItemHitTest(&lvinfo);

if(nItem != -1)

{

CString strtemp;

strtemp.Format(" 单击的是第%d 行第%d 列", lvinfo.iItem, lvinfo.iSubItem);

AfxMessageBox(strtemp);

}

*/

// 方法二:

/*

NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;

if(pNMListView->iItem != -1)

{

CString strtemp;

strtemp.Format(" 单击的是第%d 行第%d 列",

pNMListView->iItem, pNMListView->iSubItem);

AfxMessageBox(strtemp);

}

*/

*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;

m_list.SetExtendedStyle(LVS_EX_SUBITEMIMAGES);

m_list.SetItem(..); // 具体参数请参考msdn
