• CListCtrl使用技巧


    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      {

               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      {

               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;

          }

          void CTest6Dlg::AddFiles(LPCTSTR lpszFileName, BOOL bAddToDocument)

          {

               int nIcon = GetIconIndex(lpszFileName, FALSE, FALSE);

               CString strSize;

    CListCtrl使用详解

    1。先来介绍REPORT类型的CListCtrl:

    首先使用下面的语句设置CListCtrl的style:

     DWORD SetExtendedStyle( DWORD dwNewStyle );

    其中

     LVS_EX_CHECKBOXES 表示添加CheckBox

     LVS_EX_FULLROWSELECT 表示选择整行

     LVS_EX_GRIDLINES 表示添加表格线

    如果设置了LVS_EX_CHECKBOXES属性,则可以用

     BOOL GetCheck( int nItem ) const;

    来得到某一行是否Checked。

    可以先用下面的语句来删除以前的东西:

     for(int k=2;k>=0;k--) //注意要从后往前删,否则出错

      m_ListCtrl.DeleteColumn(k);

     m_ListCtrl.DeleteAllItems();

    用下面的语句新建列:

     m_ListCtrl.InsertColumn(0,_T("文件名"),LVCFMT_IMAGE|LVCFMT_LEFT);

     m_ListCtrl.InsertColumn(1,_T("仪器类别"));

     m_ListCtrl.InsertColumn(2,_T("项目类别"));

     

    其中LVCFMT_IMAGE表示可以在第一列加入图标。如果不要图标可以删去。

    然后设置列宽:

     for(j=0;j<3;j++)

      m_ListCtrl.SetColumnWidth(j ,100);

     

    以下为列表加入图标,如果不需要图标,可以跳过这一步。注意只在第一次加入,如果多次加入会出错!

    先在头文件中加入声明:

     CImageList m_ImageList;

    这是必要的,如果在cpp的某个函数中加入由于生命期结束,CImageList自动释放,则效果是列表中看不到图标,只看到一个白方块。

    下面生成CImageList,并将其绑定到CListCtrl中,这是CImageList中还没有图标,只是一个容器:

     static int flag=2;

     if(flag==2){//只调用一次SetImageList,否则出错

      m_ImageList.Create(128, 128, ILC_COLORDDB|ILC_MASK, 20, 1); 

      m_ListCtrl.SetImageList(&m_ImageList,LVSIL_SMALL);

     }

     flag=(flag+1)%2;

    如果CListCtrl已经用过,曾经加过图标进去,这时就要删除上次放进m_ImageList中的Image

     for(int kk=0;kk<m_ImageList.GetImageCount();kk++)

      m_ImageList.Remove(k);

     

    下面介绍如何向CListCtrl里面加入行,并同时为每一行动态加入图标:

    假设m_listRowCount为要加入的行数。

     CBitmap* bitmap;

     bitmap=new CBitmap[m_list1rowCount];

     HBITMAP hbitmap; 

     

     for(int i = 0; i < m_listRowCount; i++)

     {

      //为每一行插入相应的缩略图

      CFile f;

      CFileException e;  

      if( !f.Open(m_FileName, CFile::modeRead, &e )){ //m_FileName为bmp文件名,由你来定

       hbitmap = (HBITMAP)LoadImage(NULL,path+"blank.bmp",IMAGE_BITMAP,0,0,

        LR_CREATEDIBSECTION|LR_DEFAULTSIZE|LR_LOADFROMFILE);

      }else{

       f.Close();

       hbitmap = (HBITMAP)LoadImage(NULL,bmpFile,IMAGE_BITMAP,0,0,

        LR_CREATEDIBSECTION|LR_DEFAULTSIZE|LR_LOADFROMFILE);

      }

      bitmap[i].Attach(hbitmap);

      m_ImageList.Add(&bitmap[i], RGB(0, 128, 128));

      

      //插入行

      m_ListCtrl.InsertItem(i,m_FileName,i);

      m_ListCtrl.SetItemText(i,1,type);

      m_ListCtrl.SetItemText(i,2,m_Path);

     }

      

     //记得删除已经没用的临时文件

     if(m_list1rowCount!=0)

      delete[] bitmap;

    2。如果是ICON类型的CListCtrl,则要做一点点改动:

    把绑定图标集的代码由

     SetImageList(&m_ImageList,LVSIL_SMALL);

    改为

     SetImageList(&m_ImageList,LVSIL_NORMAL);

    插入行时只用

     InsertItem(i,mainSet.m_FileName,i);

    不用

     SetItemText(i,1,type);

    之类的代码。
