今天第一次用CListCtrl控件，遇到不少问题，查了许多资料，现将用到的一些东西总结如下：
以下未经说明，listctrl默认view 风格为report
相关类及处理函数
MFC：CListCtrl类
SDK：以 “ListView_”开头的一些宏。如 ListView_InsertColumn
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 ); 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); } }
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; }
17. 改变选中行的颜色 首先是添加以下消息
ON_NOTIFY( NM_CUSTOMDRAW, IDC_LIST1, OnDrawColorForMyList ) //为改变颜色添加的消息
再添加类成员函数,就OK了:
代码语言：javascript复制//改变 m_List 控件单行的颜色
void CSSDTDlg::OnDrawColorForMyList( NMHDR *pNmHdr, LRESULT *pResult )
{
NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>( pNmHdr );
*pResult = CDRF_DODEFAULT;
if ( CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage )
{
*pResult = CDRF_NOTIFYITEMDRAW;
}
else if ( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )
{
*pResult = CDRF_NOTIFYSUBITEMDRAW;
}
else if ( (CDDS_ITEMPREPAINT | CDDS_SUBITEM) == pLVCD->nmcd.dwDrawStage )
{
COLORREF clrNewTextColor, clrNewBkColor;
int nItem = static_cast<int>( pLVCD->nmcd.dwItemSpec );
//选中行显示字体为红色,否则为黑色
if(m_item == nItem) //设置为红色
{
clrNewTextColor = RGB( 255, 0, 0 );
}
else //设置为黑色
{
clrNewTextColor = RGB( 0, 0, 0 );
}
//设置背景色
if( nItem%2 ==0 )
{
clrNewBkColor = RGB( 240, 240, 240 ); //偶数行背景色为灰色
}
else
{
clrNewBkColor = RGB( 255, 255, 255 ); //奇数行背景色为白色
}
pLVCD->clrText = clrNewTextColor;
pLVCD->clrTextBk = clrNewBkColor;
*pResult = CDRF_DODEFAULT;
}
