QSystemTrayIcon - how to make one?

[slava]

Thank you. I have converted my .ico file to .png
and did:

QIcon icon ("Envelop.png");
trayIcon->setIcon(icon);

QIcon icon ("Envelop.png");
trayIcon->setIcon(icon);

To copy to clipboard, switch view to plain text mode 

the Envelop.png is in the same directory as my program but that didn't work, the system tray still shows empty icon

Use QCoreApplication::applicationDirPath() or embed it as resource. You know, the current working directory depends on how the application is launched.

Thank you very much. I did it!
