list control 【转】

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;
      }

34. 以下为一些为实现各种自定义功能的listctrl派生类

(17) 改变ListCtrl高亮时的颜色(默认为蓝色)
处理 NM_CUSTOMDRAW http://www.codeproject.com/listctrl/lvcustomdraw.asp

另外介绍了一下五个小技巧：
1.让List Control有Check Box
2.让List Box有Check Box
3.Spin Control与Edit Control的绑定
4.可以设置背景和文字颜色的Static控件
5.在Static控件中显示BMP

1.让List Control有Check Box 用SetExtendedStyle方法可以设置，看代码：（CListCtrl m_ListCtrl;） DWORD dwStyle = m_ListCtrl.GetStyle(); dwStyle |= LVS_EX_CHECKBOXES; m_ListCtrl.SetExtendedStyle(dwStyle); 2.让List Box有Check Box 首先，声明Control变量的时候用CCheckListBox代替CListBox。然后，将List Box的Has Strings属性改为True；把Ower Draw属性改为Fixed。 3.Spin Control与Edit Control的绑定首先，要让Spin Control的Tap Order紧跟着Edit Control（就是说，Spin Control的Tap Order是Edit Control的Tap Order加1）。然后，设置Spin Control的Auto Buddy和Set Buddy Integer属性为True。 4.可以设置背景和文字颜色的Static控件从CStatic类继承一个自己的Static类，相应WM_CTLCOLOR消息。下面是代码： .h文件： class ClxStatic : public CStatic { DECLARE_DYNAMIC(ClxStatic) public: ClxStatic(); virtual ~ClxStatic(); afx_msg HBRUSH CtlColor(CDC* /*pDC*/, UINT /*nCtlColor*/); void SetBackColor(COLORREF clrBack); void SetTextColor(COLORREF clrText); protected: DECLARE_MESSAGE_MAP() CBrush m_brushBack; COLORREF m_clrBack; COLORREF m_clrText; }; .cpp文件： IMPLEMENT_DYNAMIC(ClxStatic, CStatic) ClxStatic::ClxStatic() { m_clrBack = ::GetSysColor(COLOR_BTNFACE); m_clrText = ::GetSysColor(COLOR_BTNTEXT); } ClxStatic::~ClxStatic() { } void ClxStatic::SetBackColor(COLORREF clrBack) { m_clrBack = clrBack; } void ClxStatic::SetTextColor(COLORREF clrText) { m_clrText = clrText; } BEGIN_MESSAGE_MAP(ClxStatic, CStatic) ON_WM_CTLCOLOR_REFLECT() END_MESSAGE_MAP() HBRUSH ClxStatic::CtlColor(CDC* pDC, UINT /*nCtlColor*/) { // TODO: Change any attributes of the DC here m_brushBack.Detach(); m_brushBack.CreateSolidBrush(m_clrBack); pDC->SetBkColor(m_clrBack); pDC->SetTextColor(m_clrText); // TODO: Return a non-NULL brush if the parent's handler should not be called //return NULL; return (HBRUSH)m_brushBack.GetSafeHandle(); } 5.在Static控件中显示BMP 首先，给Static控件添加一个Control变量（ID要改了以后才能添加变量，也就是说ID不能为IDC_STATIC），本例为m_staticTest。然后，用ModifyStyle函数修改Static控件的Style，让它可以显示图片： m_staticTest.ModifyStyle(0, SS_BITMAP | SS_CENTERIMAGE); 最后，就是Load文件显示出来： CRect rect; m_staticTest.GetWindowRect(&rect); // 下面的方法是按照Static控件的大小显示bmp，如果要安装图片实际大小显示，用这个方法Load图片： // HBITMAP hBmp = (HBITMAP)::LoadImage(0, _T("D:\\test.bmp"), IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE); HBITMAP hBmp = (HBITMAP)::LoadImage(0, _T("D:\\test.bmp"), IMAGE_BITMAP, rect.Width(), rect.Height(), LR_LOADFROMFILE); m_staticTest.SetBitmap(hBmp); DeleteObject(hBmp); url: http://blog.sina.com.cn/rss/sitanda.xml
