The Sidebar Icon image name in OSX

Question

Is this icon included as part of the Cocoa API? What is the icon name?

I read the HIG but could not find a reference - https://developer.apple.com/library/mac/documentation/UserExperience/Conceptual/OSXHIGuidelines/SystemProvided.html#//apple_ref/doc/uid/20000957-CH92-SW1

Answer 1

It's undocumented. The image's name is NSImageNameSidebarTemplate. (NSSidebarTemplate in IB, though it's only visible at runtime).

I don't know though if this is off-limits and whether it will get you rejected.
