Snippets

Testing chars entered by users in NSTextField

(just for the case if someone else has the same problem)

1. Subclass NSTextField

2. In your subclass adopt the

        - (BOOL) textView: (NSTextView*) textView
        shouldChangeTextInRange: (NSRange) range
        replacementString: (NSString*) replacementString

method.

3. In this method you can access to the replacementString as char with the following line:

        char c = *([replacementString cString) + 0];  

4. Then you are free to examinate the conditions...
