MFC ListControl用法
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
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;
