When I say "all" I mean "all", including the margins.
Considering the method is named -boundingRect…, I wouldn't expect this. What you're looking for is the line fragment rect, and I can understand why you would think passing NSStringDrawingUsesLineFragmentOrigin as an option would yield this information. Instead, it seems to offer the bounding rect of the glyph range in line fragment coordinates, which I would surmise is more useful information in NSStringDrawing's primary intended use cases. > Therefore I believe this is a bug.

I don't know if it's a bug, per se, because the text system documentation is pretty religious about boundingRect referring only to the bounds of glyphs, and using lineFragmentRect to refer to the value you're looking for. Perhaps you should file an enhancement request for a -lineFragmentRectWithSize:… method. In the meantime, it looks like you're going to have to drop down to Core Text. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
