Yes, it's a NSView subclass in the same spirit. It implements a layout  
management policy where subviews are dynamically arranged line by  
line. Each time a line is filled with subviews, a new line is started  
and filled with the remaining subviews and so on. When the view is  
resized, the subviews are dynamically reflowed line by line as needed.
Unlike a dynamic grid layout such as NSCollectionView (added in Mac OS  
10.5), there is no underlying grid that align or snap the subviews to  
specific locations.

I don't know where the name flow layout really comes from, but the  
first time I read about it, it was the FlowLayout class in Java AWT.

Great :-)
