However, I don't seem to be able to change the selected item in the

runs the collection view, shows the values in the first object in
the collection view. But if I try to click on the second item,
nothing happens.
I read some stuff online that suggested I need to write my own
drawing code to show the selection highlight, but lacking that
shouldn't keep the collection view from handling clicks and
selecting different items, should it?
My NSCollectionItemView is an NSView containing a custom view and
two labels. All three of these show the correct values. The
CollectionView has "selectable" set.
What am I missing?
I never got it to work either.
Part of it, I think, is you have to override the view hit testing to
prevent clicks from being consumed by the individual views in the
collection. If you look at Apple's IconCollection sample code, you'll
see a hitTest: override that appears to serve this purpose.
But even after I tried to do something similar, I never got the
collection to select things using the mouse, so I gave up. (It does
work in IconCollection, but I couldn't find out why, or what was
different.) That was the 3rd time I gave up trying to use
NSCollectionView for something or other.
