That's a good question, and I hope someone has a good answer.
In the meantime, here is my workaround/kludge. I've found that
-boundingRectForFont works better than -defaultLineHeightForFont; at least
it is consistently about 30% too much, 3-4 pixels for most font sizes, so I
do this:
int RowHeightForFont(NSFont* font)
{
int ans = (int)([font boundingRectForFont].size.height - 4) ;
if (ans < 11)
ans++ ;
return ans ;
}
