Hi,
I'm attempting to recreate something kind of like iPhoto's mechanism
for refining face autodetection, like here:
http://news.cnet.com/i/bto/20090130/nicoleleeconfirm_610x381.png
In my situation, I'd like to have two NSCollectionView instances. One
on top, one on the bottom. The entries on top are the ones which my
batch processor will act on, and the ones on the bottom are the
entries which my algorithm has decided aren't candidates for the image
processing. The idea is that the user can pick entries from the bottom
and override the automatic detection and thus "move" them to the top.
And visa versa.
The trouble is, to do this I need to take the NSCollectionViews out of
their enclosing scroll views and put them both into one scroll view --
and I'd write code that queries how tall they want to be and would lay
the two of them out one over the other. That would be fine if I could
find a way to determine how tall the NSCollectionView wants to be to
display its contents. Trouble is that all the internal properties of
NSCollectionView appear to be private.
There doesn't seem to be any way to ask an NSCollectionView how tall
it wants to be, or how many rows its showing, etc etc.
Obviously, in the end I'm willing to just write a custom view that
does this manually but NSCollectionView is pretty nice in that I can
perform my bindings in IB and I get animation for free...
