The biggest problem I've found is how NSCell works. The table
view only uses one NSCell to do its drawing. Rather than having a
cell for each row of the table, it has a single cell that is
copied and released as appropriate.
This is actually a feature! It makes tables have good performance.
NSCell objects in tables can also be a pain. We wanted to have a
small table that had cells with tracking rects so that we could have
rollover buttons that worked. We've managed to hack it to work
(without subclassing NSTableView) but it wasn't easy.
This is one of the specific things I will be talking about in the
"Beyond Buttons and Sliders" talk, since it can be tricky to get
right. The talk is subtitled "Advanced Controls in Cocoa".
It would be nice if NSCell objects had this support. It would also
be useful if NSTableView objects could support NSView objects (which
would suit when you only had a small table).
Yes -- this would be nice. Please do make your voice heard by logging
bugs and feature requests; that is the best way to let the Apple
developers know what particular things the developers want to do.
Thanks!
Corbin
