Probably because it (seems to be) is a weird thing to want to know. You can do it by getting down into the NSLayoutManager used by the text view and asking it for the glyph range for the first line fragment, then converting that to character indexes and then finally extracting that from the string in the view's text storage. Roughly (untested, typed in mail): NSLayoutManager* lm = [myTextView layoutManager]; NSRange glyphRange; NSRect lineFragmentRect = [lm lineFragmentRectForGlyphAtIndex:0 effectiveRange:&glyphRange]; NSRange characterRange = [lm characterRangeForGlyphRange:glyphRange actualGlyphRange:NULL]; NSString* text = [[lm textStorage] string]; NSString* firstLineOfText = [text substringWithRange:characterRange]; (might need some finessing to sanity check ranges, not found and so on) --Graham_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
