QSystemTrayIcon help

Hi, I have 4 different images that are used as tray icons depending on the application state(on,off,starting,stopping). I want to add a ? image on the icon if a certain event occurs. So when the event occurs the icon would change to the current icon with a ? on it. Do I have to create 4 different icons or is there another way to do it?
I strongly suspect its gonna be easier to create the different icons but I'm curious to know if there's another way.

You can use QImage. Note, to get an QIcon from a QImage:

Code:

---

QIcon icon(QPixmap::fromImage(img));

---

Thanks, I'll look into that.
