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:
//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; }
}
