Hello,

I'm pretty new to cocoa and I would like to know how you can insert an
Attributed string into a NSTextView ...
I was expecting the following to do some things but I does not do much
...

NSMutableString* s = [ NSMutableString stringWithFormat: @"0x%08lx:",
fh?foff:(unsigned long)p ];
foff += sizeof(ppc_word);
tempString = [tempString initWithString: s ];
[ tempString addAttribute: NSForegroundColorAttributeName
                   value: [NSColor blueColor]
                 range: NSMakeRange(0, [ s length ])];        
[ myRTFTxt replaceCharactersInRange: NSMakeRange(0, [ [ myRTFTxt string
] length ])
                       withString: tempString ];

I would appreciate any comments, pointer, samples ...

Many thanks,
Jéré.
