，dxflowchart遇到有关问题？请大家帮忙！

求救，dxflowchart遇到问题？请大家帮忙！！！
大家好！
最近我在用第三方控件dxflowchart画流程图是遇到一个问题，烦请大家有空之余帮小弟看看：
问题是这样的：
我想对Tdxflowchart控件的连线（connection)画上箭头:
procedure TForm1.Button1Click(Sender: TObject);
var
  NewObject : TdxFcObject;
  NewConnection : TdxFcConnection;
begin
  NewObject := dxFlowChart1.CreateObject(5, 5, 25, 25, fcsEllipse);
  NewObject.Text := 'first object';
  NewObject:=dxFlowchart1.CreateObject(5,75,25,25,fcsEllipse);
  NewObject.Text:='last object';
  NewConnection :=dxfolwchart1.CreateConnection(dxflowchart1.Objects[0], dxflowchart1.Objects[1], 12, 2);
  dxflowchart1.connections[0].ArrowDest.ArrowType := fcaArrow;
end;
执行时没有箭头显示，若是连线是事先在窗体画好的，则有箭头。不知何解？请大家帮帮忙，指点一下我啊！！谢谢了！！

[解决办法]

Delphi(Pascal) code

procedure TForm1.Button1Click(Sender: TObject);var  NewObject:TdxFcObject;  NewConnection:TdxFcConnection;begin  NewObject:=dxFlowChart1.CreateObject(5,5,25,25,fcsEllipse);  NewObject.Text:='first object';  NewObject:=dxFlowchart1.CreateObject(5,75,25,25,fcsEllipse);  NewObject.Text:='last object';  NewConnection:=dxFlowChart1.CreateConnection(dxflowchart1.Objects[0],dxflowchart1.Objects[1],12,2);  dxflowchart1.connections[0].ArrowDest.ArrowType:=fcaArrow;  dxflowchart1.connections[0].ArrowDest.Width:=1 * 5 + 5;//定义箭头  dxflowchart1.connections[0].ArrowDest.Height:=1 * 5 + 5;//定义箭头end;
