MFC编程CListCtrl控件用法归纳

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 );
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!
");
Else
{
    while (pos)
    {
        int nItem = m_list.GetNextSelectedItem(pos);
        TRACE1("Item %d was selected!
", 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

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;
}
