Icons of qt -apps appear in E's system tray but for most of apps I tried, left or right -clicking them doesn't bring any menu as it should. Only cursor flashes briefly. I get error message to terminal: "QSystemTrayIcon::setVisible: No Icon set"
Apps that don't work (qt5): kopete 15.12.1, klipper (comes with kde plasma), konversation 1.6 (qt5), ktorrent 4.3.1, copyq5 2.5.0. Apps that work: clementine 1.2.3 (uses qt 4.8.7) and qbittorrent 3.3.3 (qt5). All apps' icons work with same machine when using kde plasma 5.5.3.
elementary_test with systray creates icon in systray and clicking it opens a menu as it should and selecting items gives output to terminal.
I'm using enlightenment-0.20.3 x86_64, opensuse tumbleweed, qt 5.5.1. I've got sni-qt, libappindicator(3-)1, libdbusmenu-[glib4|qt2|qt5-2] installed.
