I'm trying to code a custom toolbar panel, but I can't get an SVG to display on the toolbar button. I've tried everything I can think of, comparing with add-ons where they do work, but I just can't get my SVG to display. I did get it to work briefly before SU5, but since then. no.
It loads and displays fine in every other editor/viewer I've tried, just not in the toolbar.
Can anyone tell me how to get this to work?
I've attached my SVG file, if anyone can help it would be appreciated.
