When plain NSTextFieldCell has been set with -

However, if the NSTextField is set to handle rich text through a
call to -setAllowsEditingTextAttributes:YES, the text no longer
wraps. A quick look at the -attributedStringValue: of the field
shows that this is because the NSParagraphStyle's LineBreakMode
attribute is ignoring NSTextField's -lineBreakMode: setting and
instead going with a default of NSLineBreakByClipping.
I've submitted a bug to Apple about this, but am looking for a work
around. I thought the solution would be to programatically fill the
text field with an NSAttributedString that already had
LineBreakMode set to NSLineBreakByTruncatingTail. This works as
long as my attributed string contains some text. But if I try to
specify a string with said attributes and no text (@""), all I get
returned reference to nil, which obviously doesn't contain any
attributes.
I also noticed that the field editor's -textStorage: defaults to
the incorrect LineBreakStyle of NSLineBreakByClipping. If I replace
it with the proper LineBreakMode, everything truncates as expected.
But I run into the same problem as above: I can't actually specify
attributes for the field editor unless I also specify text.
So I'm out of ideas. Does anyone else see a solution? An error in
my reasoning? Anything?
Add the attribute when the user has finished editing the text and
leaves the field.
