I notice that in Cocoa the NSNumberFormatter class has a method
for setting a "pad" so that numbers like "12" can look like
"0012" after formating. This seems to be missing from the
GNUstep version and I'm wondering if there is another way people
tend to do this. If I want to read a series of images uploaded
form a camera the zero-pad is very helpful.
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];
I didn't realize that, thank you. Will this work in a non-gui
situation as well? I have a command line tool where I submit start
and end frames as an argument but internally I want to pad them
out. It doesn't seem that the NSNumber class has a setFormatter:
method however.
No, it doesn't. In the case of Cocoa you would use NSNumberFormatter's:
-(NSString *)stringFromNumber:(NSNumber *)aNumber
or in gnustep-base you could call -(NSString *)stringForObjectValue:
(id)obj but until NSNumberFormatter is fully implemented in gnustep-
base that's kindof academic ;-)
Cheers,
Graham.
