Question

假设有一Listview已填充好数据，要求有一Edit,输入列名，相应的列即变色，如何做到？

Answer 1

调用ListView1CustomDrawSubItem事件
不过你要把listview重画一遍
procedure TfrmQueue.ListView1CustomDrawSubItem(Sender: TCustomListView;
  Item: TListItem; SubItem: Integer; State: TCustomDrawState;
  var DefaultDraw: Boolean);
begin
  //背景颜色处理用canvas
    if subitem=3 then begin
      case TurnId of //获得不同班次的颜色
        0:listview1.Canvas.Brush.Color:=clRed;//listitem.:=clBlue;//clWindow,clBlack,clDkGray,clGray,clGreen,clPurple,clRed,clSilver,clSkyBlue,clTeal,clWhite,clYellow
        1:listview1.Canvas.Brush.Color:=clBlue;
        2:listview1.Canvas.Brush.Color:=clTeal;
        3:listview1.Canvas.Brush.Color:=clGreen;
        4:listview1.Canvas.Brush.Color:=clGray;
        5:listview1.Canvas.Brush.Color:=clPurple;
        6:listview1.Canvas.Brush.Color:=clBlack;
      end;
    end;
end;
