Is there any way to get the size that -[NSControl sizeToFit] would
resize a control to without actually resizing the control?
The description of sizeToFit: indicates that it neither redisplays the
control nor flags it as needing redisplay. Neither does -[NSView
setFrameSize:]. So, you could store the current size of the control,
call sizeToFit:, check the new size, and then restore the old size.
Since neither sizeToFit: nor setFrameSize: automagically redisplay,
there shouldn't be any visible effects from all that.
I can't say how efficient it would be, though. It depends on how "heavy"
sizeToFit: and setFrameSize: are - if all they do is recalculate the
relevant attributes in preparation for drawing, and leave any heavy
lifting to drawRect:, then it should be fine.
