NSTextField vertical sizeToFit

• Jeff NSTextField vertical sizeToFit Apr 13 2008, 10:38
  Any way to take an NSTextField containing some amount of text, and resize it
  vertically so all the text fits within the frame? The sizeToFit message
  seems to do this, except on the horizontal axis.
  Thank you!

  If you mean one line of text, there was [NSFont
  defaultLineHeightForFont] but that's depracated in 10.4 and you're
  supposed to use a layout manager (NSLayoutManager).
  
  If you mean multiple lines of text, you must calculate it using a
  layout manager.  But I could never find a typesetter behavior which
  gave a reliably accurate answer for an NSTextField.  The closest is
  NSTypesetterBehavior_10_2_WithCompatibility.  It seems to me that
  Apple discourages multi-line NSTextFields.  (You can't make one in
  Interface Builder).  My advice: If it's more than one line, use
  NSTextView instead.  A few months ago I put together a demo which
  explains these issues.  You might want to run it, read the comments at
  the top of NS(Attributed)String+Geometrics.h, and/or check out the
  references.

  Let me know if I made any conceptual errors in that thing.

  It's a little easier to do this with an NSTextView:
  
  NSRect frame = NSMakeRect(0, 0, someWidth, MAXFLOAT);
  NSTextView *tv = [[NSTextView alloc] initWithFrame:frame];
  [[tv textStorage] setAttributedString:someAttributedString];
  [tv setHorizontallyResizable:NO];
  [tv sizeToFit];
  
  You can do a similar process with an NSTextField, but you have to set
  the NSParagraphStyle to word wrap, and I find it easier to just
  configure an NSTextView. If you need an NSTextField, I can walk
  through that.
