Most of Apple's own icons in the menubar have always been monochrome. This is not true for 3rd party applications. If those show an icon it's often their app icon (which I think is the general idea for icons put up through `KStatusNotifier`).

Beyond the fact that `setIsMask` was introduced only in Qt 5.6 I see that the actual icon-setting is done by `QSystemTrayIcon::setIcon()`. I'd propose that the decision whether or not to make a monochrome version of the icon can be left to Qt (esp. if one's supposed not to change Qt's native platform theme by default O:-) )

I'm not sure what to expect here, what effect is using `i18nc("!")` going to have? AFAIK the exclamation mark is pretty universal, and translating it might reduce the label's effectiveness. I've tried many options to label the Dock icon (that's what we're talking about here) and found no better alternative.

If you're referring to `overlaySize`: I'll need to initialise it to some value if the application doesn't have (or no longer has) an icon set. I don't remember exactly where the 22 comes from, that's probably the standard height for MenuExtra icons.
The `0.667` (2/3) value a bit further down is again a hand-tuned scale factor which I find a good compromise which puts a reasonably sized dot at an appropriate location on the icon.

Do you have a better suggestion?

Texted separators do not exist in menu items in the OS X "global" menubar (they become regular separators), and Qt will not provide a platform-specific implementation. Loss of the section title text is maybe not always an issue, but I think it is in the system tray menu. I therefore propose to emulate `QMenu::addSection` by replacing the texted separator with an inactive (disabled) menu item that shows the text, followed by a standard separator. Menus in the notification area are much less subject to interface guidelines, so the presence of an item icon is acceptable and IMO useful for the `titleAction`.

Adding a few qDebug statements shows that the `attentionIcon` is empty.
