When I put PNG icon, it works, but not the SVG. @ttuegel please help! :) wrapQtProgram doesn't make any change.

You still need wrapQtProgram or your users will get segfaults randomly.

I see you did include qtsvg, but is the .pro linking against it? If the PNG works, but not the SVG, that suggests qmake is building the PNG into the executable by mistake; you can check the .pro for that too, I believe.

Can't get tray icon to show. The program uses the following code
src/views/mainWindow/MainWindow.cpp

  QIcon icon = QIcon(":/resource/pic/logo.svg");
  trayIcon->setIcon(icon);
  setWindowIcon(icon);

When I put PNG icon, it works, but not the SVG. @ttuegel please help! :) wrapQtProgram doesn't make any change. Maybe it's just because I'm on 17.03-beta channel, and the package is built with the stuff from master, dunno.

@ttuegel Thank you! It's linking:

$ ldd bin/mytetra | grep -i svg
        libQt5Svg.so.5 => /nix/store/mr1l6i5wnvi1jlnm5f439jxyx51lcmfn-qt-5.7.1/lib/libQt5Svg.so.5 (0x00007f7700c39000)

libpng too, since some UI elements are png images

libpng16.so.16 => /nix/store/lbq1pdql98h7xh25j4rx8k7gyrvy77fa-libpng-apng-1.6.28/lib/libpng16.so.16 (0x00007f1a60d60000)

Also this program uses a lot of svg icons in the UI, they are rendered correctly. But tray icon is not visible - again svg is used for that, if I swap it with other format like png - then tray icon becomes visible

What tray are you using? It might not support SVG icons. In any case, it doesn't sound like a problem on the Qt side, if the rest of the SVG icons render correctly.

@ttuegel Standard KDE Plasma 5 tray

@ttuegel
Most other programs use either png icon for tray or QSvgRenderer
To keep things simple, I'll just make it use png icon and mark this PR as ready
Thanks
