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;

      }

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
