If you QIcon::pixmap() for an SVG-only icon, this should just create a painter itself and draw to it. Hence you might not see the debug output of the main painter, but the results should be identical. > But I think you should use QSvgRenderer, it works but it needs the filenames. I am not sure where the difference to using QIcon is and I suspect it uses QSvgRenderer internally. In any case, I do want to draw the platform-supplied icons which often are pixmaps and I use the SVG icons as fallbacks only. I'll look at the Qt source code what QIcon actually uses to draw onto a QPainter. Have you tried to use QSvgRenderer directly? (Maybe using a resource path like ":/icons/image-loading.svg".) > Best Regards, > Razi > Best regards, Adam. -- You received this question notification because you are a member of qpdfview, which is an answer contact for qpdfview. -- Mailing list: https://launchpad.net/~qpdfview Post to : [email protected] Unsubscribe : https://launchpad.net/~qpdfview More help : https://help.launchpad.net/ListHelp
