macOS Detect when the radio buttons selection changed.

[joaop]

I want to detect which button is selected without the user pressing any button, is there a way to do it? Then, when the user pressed the button I want to change a Text Field text, which I also don't know how to do exactly. Thanks in advance.

With all the respect I don't see how this can help me. If it is because of 's documentation, I already make a search on it and still can't find out how to do what I want to.

I believe Sydde is telling you that you have a lot of work ahead of you.

For radio buttons, take a look at
http://developer.apple.com/library/...ns.html#//apple_ref/doc/uid/20000252-BCIBFHAA

For changing the text field, look at the documentation for NSText (?).

Patrick has a good point. I would recommend starting with the tutorials. Apple has put a couple in the developer section, and there's a few books on the subject in your local bookstore.

I don't understand, for text fields we can easily detects if the text was changed (without any button), and for radio buttons no. That's weird, I'll continue my research if I find anything important I'll keep you guys updated here, maybe I can help other folks.

OMG I made some test and then I figured out how to do it, since I was making 1 IBAction method to detect which check box was pressed, in interface builder I linked it up with the entire NSMatrix, but since each button is one button the correct code needs one IBAction per radio button, the rest was easy. Thank you guys for your help.
