问个有关问题，dw中有一列数据很长，如果让设置成自动行高很影响版面美观，小弟我想实现用鼠标只上去就想tooltip一样显示其全部内容，可以实现吗

//================================================================================// Script - ue_display_column for u_dw_base // Reason: 显示列值//--------------------------------------------// Modified By: qin_phoenix        Date: 2009.10.15//--------------------------------------------////================================================================================If ii_DwId = 0 Then Return 0if lb_set_column_display then         if lower(dwo.type) = 'column' then                 Integer li_X, li_Y         String ls_Text                                                //根据数据窗口列的位置和名称设置ToolTip控件            If dwo.Type = "column" Then                            If String( dwo.Name ) <> is_ColName Then                                         li_X = UnitsToPixels( Integer( dwo.X ),XUnitsToPixels! )                    li_Y = UnitsToPixels( Integer( dwo.Y ), YUnitsToPixels! )                                        //更新ToolTip控件窗口                    inv_ToolTip.of_UpdatetipRect( This, ii_dwID, li_X, li_Y, &                                    li_X + UnitsToPixels( Integer( dwo.Width ), XUnitsToPixels! ), &                                            li_Y + UnitsToPixels( Integer( dwo.Height ), YUnitsToPixels! ) )                                    //引用各列的列名作为提示文本                    is_ColName = String( dwo.Name )                    ls_Text = This.Describe( is_ColName + "_t.Text" )                    inv_ToolTip.of_settiptext( This, ii_dwID, "请输入" + ls_Text )    End IfEnd IfReturn 0            end if                end if
------解决方案--------------------
主要是要解决在mousemove 事件中如何获取到该行的数据。
用行高和xpos 计算鼠标所在行试试。
