If you mean -paddingCharacter and -setPaddingCharacter: these are  
only available with NSNumberFormatterBehavior10_4 and GNUstep's  
NSNumberFormatter doesn't implement that behaviour at all.  However  
you can do what you want in the 'original' NSNumberFormatter anyway:

        NSNumberFormatter *fmt=[[[NSNumberFormatter alloc] init] autorelease];
        [fmt setFormat:@"0000"];
        [[textField cell] setFormatter:fmt];

(warning: typed into Mail, lightly tested, blah) should put leading  
zeroes.

Cheers,
Graham.
