[[qanda:topic_unsolved]] Is it possible to set a zoomFactor outside 0.25~5

I'm developing an SVG viewer. I tried QSvgRender+QGraphicsView, but it doesn't support text selection with the mouse. Finally, I find QWebEngineView works well. However, the zoomFactor range is 0.25~5 which is a shortcoming. I want to remove the limit and don't know if this thought is possible. Thanks!
