The solution was simpler than I thought.
something.h file a line like:
NSMutableAttributedString *theAS;
int charIndex = 0;
something.m file in an init method somewhere:
NSMutableAttributedString *theAS = [[NSMutableAttributedString alloc] initWithString:@"AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz"];
charIndex = 0;
something.m file in an action or message received method:
if ( charIndex < [ [ theAS string ] length ] ) {
NSRange nxt2Chars = NSMakeRange ( charIndex, 2 );
[ theAS beginEditing ];
[ theAS addAttribute: NSBackgroundColorAttributeName
value: [ NSColor orangeColor ]
range: nxt2Chars ];
[ theAS endEditing ];
[ currentDataTextBox setAttributedStringValue:theAS ];
}
charIndex += 2;
Depending on how you implement this you may have to turn off the previous selection as well in the NSMutableString.
Thanks again to all who assisted!
