NSStatusBar drag & drop with menu
===

I'm familiar with the technique described here: http://stackoverflow.com/questions/5663887/drag-and-drop-with-nsstatusitem to make an NSStatusBar item that can handle file drag & drop.

What is the proper method for having a status bar item that supports both drag & drop and regular menu interactions, much like the Cloudapp icon does.

I want users to be able to left click the NSStatusItem to see the normal menu listing as well as allow for file drag and drop functionality.
