It's OS X.  I don't believe it's called a "System tray" in OS X, but as far as Qt is concerned, it's the area where QSystemTrayIcons go.  

I had initially thought that it was 2 icons as well, but that doesn't *appear* to be the case - the whole thing highlights on click & the menu always appears in the same place, regardless of where I click.  I suppose there could be quite a bit of trickery at play here, but I wanted to ask before I started investigating if it's worth trying to use two icons & make them appear as one.
