Hi Riccardo:
The information you are looking for is not in the NSTextField
documentation, but in the NSControl documentation, NSTextField's
superclass. You can find it in the Cocoa Reference docs others have
sent links to. Welcome to the joys of subclasses!
FYI, the method you are looking for is stringValue. You can
retrieve the value of any control as a string by using this method:
[myControl stringValue]
Likewise, you can set the value of any control as a string by using
the method:
[myControl setStringValue: @"The String"] ;
This is a great aspect about Cocoa because it allows you to replace
controls with other controls without changing any code. I recently
changed a user interface widget on the program I am working on from a
stepper to a slider without changing any code...it was very exciting! :-)
Cheers,
-Charles

Hi everybody,
I'm new to COCOA, NexTStep and other things but I wanted started
programming with OS X using Cocoa and Objective - C.
The question is I wanted to create a very simple program : a cocoa app
in which by pressing a button you will see a string appearing on a
textfield... quite simple, isn't it ? :-))
I can't manage to get things work; here's the passages I've done...
1) Create the interface
2) create a subclass of NSObject with an outlet and an action in it
3) Istantiate the subclass
4) Made the connections in a correct way ( I used printf to check it)
Now in the developer docs I can't find the way to make my cocoa app
modify the inside of the textfield. What method have I to give it ?
Where can I find it on the documentation on my hard disk (tidy X and
developer tools installation) ?
Thank you for your help .
