Re: NSCollectionView questions

I needed to put a pop up menu inside a view of a NSCollectionViewItem, 
then customize the contents of the menu using the representedObject.

I subclassed NSCollectionViewItem and augmented setView to cause 
"self" to be the delegate of the NSPopUpButton menu, obtained with 
[view ViewWithTag:n].

That subclass has a method for MenuNeedsUpdate which passes the 
message to its NSCollectionView along with a copy of the 
representedObject.

My subclass of NSCollectionView has an IBOutlet for the Window 
Controller, so it can pass the message there where the menu can be 
customized.

Hope that helps,
DC
