I have seen one other post asking this question so I will throw it
out here and see if anyone has experienced: I have an NSTableView
with 3 NSButtonCells on it. Two are checkbox style one is bevel
style (aping the iTunes arrow link.) The bevel style cell works
swimmingly and gives me no grief (other than clicky text) but the
checkbox style cells slow the scrolling in my table. Any time they
are involved in a paint operation the scrolling gets very jerky. I
have turned them off and changed their style and can confirm that
either operation returns the scrolling to smooth and normal. I am
not doing anything with these cells in code or using value
formatters. They are simply dropped onto a column with a 1 or a 0.
Has anybody else experienced this and/or know a solution?
It's a known issue. Select the cell in IB and set the scaling to "None".
Also, in the future, if you have a performance issue, take a
'sample' (from the command line) and a Shark trace. Post that info
along with your description, and it will greatly help people in
determining the source of your problem.
thanks!
