I'm wondering how I can set up a text field control so that when the user presses enter(and or return) it triggers some kind of event to let the application know that it can extract the data from the control and manipulate it's contents
Thanx in advance

</font><blockquote><font size="1" face="Geneva, Verdana, Arial, sans-serif">code:</font><hr /><pre style="font-size:x-small; font-family: monospace;">- (IBAction)catchTextFieldDidEndEditing  NSTextField *)sender
{
//do something
}</pre><hr /></blockquote><font size="1" face="Geneva, Verdana, Arial, sans-serif">Then, you need to set your textField's action method ot be catchTextFieldDidEndEditing: Hopefully the class that you put this method in is instantiated in IB (usually its your controller class). All you have to do is add this method to the set of action methods for the class that should catch the end editing event and then draw a connector from the text field to your instantiated object and select the appropriate action method (Is it control drag or option drag, I never remember).
If any of this lost you, I'd suggest reading the Currency Converter Cocoa tutorial.

There are plenty of examples online, and you can find a great walk-through in Aaron Hillegass's book "Cocoa Programming for Mac OS X" that takes you through the steps. Once you "get" how to do this, using any kind of control is pretty much the same procedure.
See <a href="http://www.bignerdranch.com" target="_blank">http://www.bignerdranch.com</a> for his book...but there are plenty of good programming sites around that have good examples and are free to boot.

I'm using c++ using the carbon frameworks but I think I follow the ObjC example. I'll give it a try
