Either I'm misunderstanding your question, or you're misunderstanding the Geometries code. I think you want -widthForHeight:attributes:, with the height specified for three lines (could just take it from what IB sets for you, or first get a heightForWidth:reallyBig, then triple that). The demo program has a -heightForWidth:attributes: case, just flip it around. This code _does_ work for a multi-line height, and does allow for correct wrapping, font changes in mid fly, multibyte characters, and all the rest. -==- Jack Repenning [EMAIL PROTECTED] Project Owner SCPlugin http://scplugin.tigris.org Subversion for the rest of OS X ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: horizontal sizeToFit of NSTextView or NSTextField
Now I want to be able to calculate the optimal width of the view so that the entire text is visible. This worked wonders for me: http://www.cocoabuilder.com/archive/message/cocoa/2008/3/31/202752 This also does not solve my problem.

I don't think that there is really a way in Cocoa or Quartz that solves this problem. So I really have to try different widths, let the layout manager layout the text and see how much lines it needs. So I can do a binary search to get an ideal width. Even if Cocoa or Quartz would have a method for calculating the width, it would internally also have to do such a binary search. I don't think that it's possible to calculate the perfect width in one step. So I just do it myself and it works quite well.

Re: horizontal sizeToFit of NSTextView or NSTextField
If you wish to vary both the width and height to be a more pleasing set of dimensions, similar to what an alert does, try word wrapping your text into a golden ratio rectangle using the area measurement generated by your single-line text measurement. Of course, based on a strict interpretation of what I'm reading from you, with the height bounded, keep in mind that a square that is one foot high and 18 feet wide has the same area as a square that is three feet high and six feet wide. Of course, since we're talking about text that isn't cleanly broken at character positions, you'll probably need some ceiling breaks on the width area recalculation.
