Cocoa can't very well do *everything* for you. If it did, we'd all be
out of a job, for one.... Personally I find that Cocoa provides plenty
of facilities and building blocks for more. Just because it doesn't do
what you want in this one particular case certainly doesn't make it
generally deficient.
However in this case Cocoa is able to do what you want, using built-in
features and nothing more. Simply create an NSAttributedString
containing your image and your text, and using the available
attributes to control horizontal and vertical spacing. A plain
NSTextFieldCell can display an NSAttributedString with no
customization.
