How to add popup menu on NSToolbar item?

I've tried to 开发者_Python百科add NSPopupButton + CustomView, but it's not what I wanted. I would like to mimic "Tasks" on Xcode's toolbar.

You want to change the 'Type' of the NSPopUpButton to "Pull Down."

Here's a great video demonstration on precisely what you're looking for: http://www.youtube.com/watch?v=Qr6EX-JIZZU.

Hey Irwan, I have code that does this in my Fluidium project on GitHub.

Behavior: Standard NSToolbarItem that is an NSButton. When you click and hold on the button, it pops up an NSMenu after a short delay.

Basically identical to Xcode:
