If this is possible with the Qt HDPI approach (i.e., if it does not requires those @2x icon bitmap files). I have not checked that, but if I understand this correctly, it should be possible: http://blog.qt.digia.com/blog/2013/04/25/retina-display-support-for-mac-os-ios-and-x11/ Quote: "As we have seen, raster content won’t look nice when scaled and high-resolution content should be provided. As an app developer you have two options: (ignoring the “do-nothing” option) - Replace existing raster content with a high-resolution version - Provide separate high-resolution content The first option is convenient since there is only one version of each resource. However, you may find (or your designer will tell you) that resources like icons look best when created for a specific resolution. To facilitate this, Qt as adopted the “@2x” convention for image filenames:" SVG would be "first option", no? Jürgen > > JMarc > >
