nodeIconButton size

Are images on nodeIconButton resizable?

I can’t seem to find the appropriate way to do this, setting the size of the button with width and height only resizes the button’s ui and it’s image remains the same size.

It looks like images are based on the size of the control, and it uses image1 image2 or image3 based on what size is most appropriate?

Follow up question, is it possible to use a QPixmap as the image for a button? Or is that mixing two UI frameworks that don’t work together?
