大家好,又见面了,我是你们的朋友全栈君。
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
-
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” -
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styleDWORD 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 -
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 -
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 -
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); -
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);
}
} -
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
}
} -
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 -
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++;
} -
使listctrl中一项可见,即滚动滚动条
m_list.EnsureVisible(i, FALSE); -
得到listctrl列数
int nHeadNum = m_list.GetHeaderCtrl()->GetItemCount(); -
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); -
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; }
-
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; }
-
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; }
-
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; }
