[solved]Invisible system tray icon
I created tray icon:
trayIcon = new QSystemTrayIcon(this);
But in tray it's invisible, only empty place, and instead of one, appears two 'icons\empty places' and if add events to show\hide window and click each empty place - appears two different windows and I can write different text in each.
I read something about creating .qrc file and adding 'icon' prefix and file, but I use visual studio qt addin and don't know what I shoulde do there.
It's because your path is absolute thus at run time it tries to find the file in C:/Resources/tryIcon.png. Here you have an explanation on how to handle resource with the Qt Addin.
Hope it helps
Finally i solved the problem. I just created usual notepad file, then renamed it to .qrc file and in VS it opened without any problems
