As soon as we use the rcc file for the icons, we set an icon theme name. If you have an icon theme name set, QIcon::fromTheme will do: bool hasUserTheme = QIconLoader::instance()->hasUserTheme(); QIconEngine * const engine = (platformTheme && !hasUserTheme) ? platformTheme->createIconEngine(name) : new QIconLoaderEngine(name); This IMHO means no longer KIconLoader will be used at all. (On Windows it will never be used, as the platform theme doesn't use it there anyways I assume) But yes, packaging Breeze Dark icons in addition will not help to fix this :/ REPOSITORY R266 Breeze Icons REVISION DETAIL https://phabricator.kde.org/D25119 To: cullmann, #frameworks, vonreth, dfaure, rempt, ndavis, mart, alex-l Cc: davidedmundson, broulik, rempt, kde-frameworks-devel, LeGast00n, GB_2, michaelh, ngraham, bruns
