Determine whether an NSMenu is opened

I have an NSMenu w开发者_高级运维hich opens when a user clicks an NSStatusItem in the status bar. How can I determine if the NSMenu is opened (expanded) or not?

Thank you!

You can use the NSMenuDelegate protocol to handle menuWillOpen and menuWillClose messages. Use menuWillOpen to set a boolean that states that the menu is open, and menuWillClose to turn it off.

Update: Looks like menuWillClose: is no longer an available delegate method. Use menuDidClose: instead.
