I have a normal NSTextField which i need to ensure has no line
breaks in it. It works well since there is a default button that
traps the enter and return keys. but if i go into TextEdit and type
two lines
line 1
line 2
and copy both lines, and return to my app and paste the clip board
into the NSTextField, both lines are entered. you need to up arrow
to see the line 1 but it is there.
question: how do you stop the multi line input? NSTextFieldCell has
a set clip mode method but that is more about how the clipped text
is drawn. I need to stop it entering in the first place.
Does writing a custom NSFormatter help? See especially the
isPartialStringValid:... methods, though they talk about _typing_
input; possibly they wouldn't catch pasted text. I'm sorry I don't
have time to verify this.
