svg item problem in qwt

I have a plot that contains some svg items with using QwtPlotSvgItem. And I also use mouseEvents on these svg items. But when I zooming with mouse wheel these svg items scale are changing. I want them stable. I mean they should not effect to zooming. I used this;

Source code

QwtPlotSvgItem *item = new QwtPlotItem;

and it didnt work. Secondly I added zoomAndPan = "disable" this tag to inside svg file. it didnt work again. I dont know what I am missing.
Is there any advice for it?
