VS2010中新控件的编程------CMFCListCtrl列表控件的应用

CMFCListCtrl列表控件的应用

   首先建立以CMFCListCtrl为基类的CMyListCtrl，并重载OnGetCellTextColor以便设置文本颜色，重载OnGetCellBkColor以便设置背景颜色，重载OnGetCellFont以便设置字体，重载OnCompareItems以便按照一定规则排序。重载的关键函数如下：

COLORREF CMyListCtrl::OnGetCellTextColor(int nRow,int nColum)

{

         if (!m_bColor)

         {       

                   return CMFCListCtrl::OnGetCellTextColor(nRow,nColum);

         }

         if (m_bRowTextColorIsRed[nRow] == TRUE)

         {

            returnRGB(100, 0, 0);

         }

         if (nRow % 2 == 0)

         {

            returnRGB(40, 40, 40);

         }

         if (nRow % 2 !=0)

         {

            returnRGB(50, 50, 50);

         }

}

COLORREF CMyListCtrl::OnGetCellBkColor(int nRow,int nColum)

{

         if (!m_bColor)

         {

            returnCMFCListCtrl::OnGetCellBkColor(nRow, nColum);

         }

         COLORREFcolorRef;

         switch (m_nMyColorStyle)

         {

         case 0:

                   colorRef= (nRow % 2) == 0 ? RGB(167, 191, 222) : RGB(211, 223, 238);

             break;

         case 1:

                   colorRef= (nRow % 2) == 0 ? RGB(191, 177, 208) : RGB(223, 216, 232) ;

            break;

         case 2:

                   colorRef= (nRow % 2) == 0 ? RGB(205, 221, 172) : RGB(230, 238, 213) ;

                   break;

         }

         return colorRef;

}

HFONT CMyListCtrl::OnGetCellFont(int nRow,int nColum,DWORD dwData )

{

         if (!m_bModifyFont)

         {

            return NULL;

         }

         if (nRow == nCurrentSel)//

         {

            returnafxGlobalData.fontDefaultGUIBold;

         }

         return NULL;

}

intCMyListCtrl::OnCompareItems(LPARAM lParam1, LPARAM lParam2,int iColumn)

{

         CStringstrItem1 = GetItemText((int)(lParam1

         CStringstrItem2 = GetItemText((int)(lParam1

         if (iColumn == 0)

         {

            int nItem1 =_ttoi(strItem1);

            int nItem2 =_ttoi(strItem2);

            return(nItem1< nItem2 ? -1 : 1);

         }

         else

         {

            int iSort =_tcsicmp(strItem1, strItem2);

            return(iSort);

         }

}

对于CMyListCtrl的引用，添加数据后，可以得到相应颜色和底色的列表框，可以在列表框的双击消息中加入引用代码，使得双击后的行字体变黑。

         POSITION pos = m_List.GetFirstSelectedItemPosition();

         if(pos == NULL)

         {

                   TRACE(_T("No items were selected!\n"));

         }

         else

         {

                   while (pos)

                   {

                            int nItem = m_List.GetNextSelectedItem(pos);

                            TRACE(_T("Item %dwas selected!\n"), nItem);

                            m_List.nCurrentSel= nItem;

                   }

         }

         m_List.RedrawWindow();
