This is possible, but the documentation does not say anything about
this being necessary.

Well, the documentation for setUpFieldEditorAttributes: says:
Sets up the field editor. You never invoke this method directly;
by
overriding it, however, you can customize the field editor.
I have no need to customize it...the default one it provides is just
fine.

I was thinking the same thing and this would likely be just fine in my
specific case (and I am about to see if I can use sizeToFit to solve
my problem), but I am now just as interested in the general question
of how to correctly and generally get metric information for a
NSTextField.
Thanks again for your comments. They are useful.
If anyone is interested, I've posted a sample application
demonstrating the problem at:
http://ericgorr.net/cocoadev/label/TextFieldMetric.zip
It uses the drawRect: as described below.
If this is indeed a cocoa bug, I will report it.
If not and if anyone has any ideas on a reliable way to get metric
information for a NSTextField, please let me know.
