Commit all capitals to NSTextField (Cocoa)

Question

Is there a way to force capitals into an NSTextField?

I want to create a text box for entering postal codes, and I want all postal codes to be entered in capital letters.

eg. N1 3ET instead: n1 3et

In addition, I use a regular expression that only accepts capitals (I know little about regular expressions, so I don’t want to change it)

Thank!

Answer 1

You can provide an NSTextField delegate with something like:

- (void)controlTextDidChange:(NSNotification *)aNotification{
    NSText *fieldEditor = [[aNotification userInfo] objectForKey:@"NSFieldEditor"];
    [fieldEditor setString:[[fieldEditor string] uppercaseString]];
}

It should catch notifications of text changes and write the text in uppercase.
