【VS开发】CListCtrl控件使用方法总结

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

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 );

}

else //设置为黑色

{

clrNewTextColor );

}

//设置背景色

)

{

clrNewBkColor ); //偶数行背景色为灰色

}

else

{

clrNewBkColor ); //奇数行背景色为白色

}

pLVCD->clrText = clrNewTextColor;

pLVCD->clrTextBk = clrNewBkColor;

*pResult = CDRF_DODEFAULT;

}
