Highlight NSStatusItem when triggered programmatic

问题:

I have an NSStatusItem with an attached menu that I'm triggering with a global hotkey. If I click the menu item I get the highlight as usual, if I use the hotkey the highlight isn't triggered. Does anyone know a way to trigger the highlight?

I've tried overriding the view and drawing it myself in drawRect but if there is a nicer way to do it I'd love to hear. Thanks!

The reason I don't want to override the view is then I have to handle icon positioning, clicking to activate the menu, etc.

This does the magic in macOS 10.13.6 with Xcode 10.

guard let m = statusItem.menu else { return }
statusItem.button?.isHighlighted = true
statusItem.popUpMenu(m)
statusItem.button?.isHighlighted = false

Please note that last line is required to de-highlight the icon when the menu gets closed.

Use:

[[statusItem button] highlight:true];

As it turns out setHighlighted: and highlight don't do the same thing:
NSStatusBarButton keep highlighted
