CTreeCtrl和CListCtrl落空核心时高亮选中项

    添加时间:2013-7-25 点击量:

    设置CTreeCtrl的Always Show Selection:True
    CListCtrl的Always Show Selection:False
    在NM_CUSTOMDRAW事务中添加如下代码:

    void CHighLightDlg::OnNMCustomdrawTree1(NMHDR pNMHDR, LRESULT pResult)
    {

    以下未经申明,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具体材料


          直观的懂得:windows资料经管器,&#8220;查看&#8221;标签下的&#8220;大图标,小图标,列表,具体材料&#8221;







    2. 设置listctrl 风格及扩大风格


          LONG lStyle;
          lStyle = GetWindowLong(m_list.m_hWnd, GWL_STYLE);//获取当前窗口style
          lStyle &= ~LVS_TYPEMASK; //清除显示体式格式位
          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(只实用与report风格的listctrl)
          dwStyle |= LVS_EX_GRIDLINES;//网格线(只实用与report风格的listctrl)
          dwStyle |= LVS_EX_CHECKBOXES;//item前生成checkbox控件
          m_list.SetExtendedStyle(dwStyle); //设置扩大风格
      
          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, &#8220;11&#8221;);//插入行
          m_list.SetItemText(nRow, 1, &#8220;jacky&#8221;);//设置数据


     





    4. 一向选中item

        选中style中的Show ion always,或者在上方第2点中设置LVS_SHOWSELALWAYS






    5. 选中和作废选中一行


        int nIndex = 0;
        //选中
        m_list.SetItemState(nIndex, LVIS_SELECTED|LVIS_FOCUSED, LVIS_SELECTED|LVIS_FOCUSED);
        //作废选中
        m_list.SetItemState(nIndex, 0, LVIS_SELECTED|LVIS_FOCUSED);
     





    6. 获得listctrl中所有行的checkbox的状况


          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为选中状况), i);
                    AfxMessageBox(str);
               }
          }







    7. 获得listctrl中所有选中行的序号




          办法一:
          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);
               }
          }


          办法二:
          POSITION pos = m_list.GetFirstSelectedItemPosition();
          if (pos == NULL)
               TRACE0(No items were ed!\n);
          else
          {
               while (pos)
               {
                    int nItem = m_list.GetNextSelectedItem(pos);
                    TRACE1(Item %d was ed!\n, nItem);
                    // you could do your own processing on nItem here
               }
          }







    8. 获得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);


          关于获得设置item的状况,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. 获得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,即迁移转变迁移转变条

        m_list.EnsureVisible(i, FALSE);





    11. 获得listctrl列数

        int nHeadNum = m_list.GetHeaderCtrl()->GetItemCount();





    12. 删除所有列


          办法一:
             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。


          办法二:
          int nColumns = 4;
          for (int i=nColumns-1; i>=0; i--)
              m_list.DeleteColumn (i);







    13. 获得单击的listctrl的行列号


          添加listctrl控件的NM_CLICK消息响应函数
          void CTest6Dlg::OnClickList1(NMHDR pNMHDR, LRESULT pResult)
          {
               // 办法一:
               /
               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);
               }
              /
       
              // 办法二:
              /
               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. 断定是否点击在listctrl的checkbox上


          添加listctrl控件的NM_CLICK消息响应函数
          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);
               //断定是否点在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消息响应函数
          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切换核心时(包含用键盘和鼠标切换item时),状况的一些变更次序


          添加listctrl控件的LVN_ITEMCHANGED消息响应函数
          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 ed,pNMListView->iItem);
               }
               else if((pNMListView->uOldState & LVIS_SELECTED) == 0 &&
                (pNMListView->uNewState & LVIS_SELECTED) == LVIS_SELECTED)
               {
                    sTemp.Format(%d got ed,pNMListView->iItem);
               }
        
               pResult = 0;
          }

          m_list.SetItem(..); //具体参数请参考msdn


     





    21. 在CListCtrl显示文件,并按照文件类型来显示图标


          网上找到的代码,share
          BOOL CTest6Dlg::OnInitDialog()

               return  -1;
          }







    22. listctrl内容进行大数据量更新时,避免闪烁


          m_list.SetRedraw(FALSE);
          //更新内容
          m_list.SetRedraw(TRUE);
          m_list.Invalidate();
