Yes, and since it's a replacement for other non-Finder-icon-view type things 
(e.g. IKImageBrowserView), its the wrong behavior. That's why I said "matrix of 
items". Finder icon view is not that—they can be arranged with complete 
disregard to columns and rows.

You mean it selects like Finder icon views have since 1984? Like a collection 
of discrete items instead of a continuum?

NSCollectionView selection behavior is insanely bad

2017-04-26 Thread Steve Mills 
Since IKImageBrowserView is deprecated and buggy in recent versions of macOS, 
I've been switching to NSCollectionView. Holy crap, does its selection behavior 
suck. Instead of doing the right thing when shift-clicking (selecting a range 
from the anchor), it simply adds/removes the clicked item to/from the 
selection. That's unlike pretty much any Apple matrix-of-items selection 
behavior ever. I've been trying to make it right by subclassing 
NSCollectionView to override mouseDown:, mouseDragged:, mouseUp:, 
setSelectionIndexPaths:, selectItemsAtIndexPaths:scrollPosition:, 
deselectItemsAtIndexPaths:, selectAll:, and deselectAll:, as well as keyDown:, 
keyUp:, and tons of the moveUp/Down/Backward/Forward*: methods.

Has anybody done this, or just lived with the half-assed default 
implementation? Anybody know of a free public implementation or even a complete 
replacement for NSCollectionView that handles shift-key selection the right 
way? Coupled with the other bugs/problems I've asked about and not gotten any 
answers to, there's got to be something better out there than NSCollectionView.
