NSTextField vertical sizeToFit
-
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.
